f1dc03d0cc docker development image and helper makefile
separate makefile and build env:

- separate makefile for docker
- only show docker commands when docker detected in system
- only rebuild container on change
- use an unpriviliged user

builder image and base dev image:

- fully isolated environment inside container.
- all venv installed inside container shell and available as commands.
    - ex: `docker run IMG jupyter notebook` to launch notebook.
- pure python based container without poetry.
- custom motd to add a message displayed to users when they connect to
container.
- print environment versions (git, package, python) on login
- display help message when starting container

d22651d82a Add new iFixit document loader (#1333)
iFixit is a wikipedia-like site that has a huge amount of open content
on how to fix things, questions/answers for common troubleshooting and
"things" related content that is more technical in nature. All content
is licensed under CC-BY-SA-NC 3.0

Adding docs from iFixit as context for user questions like "I dropped my
phone in water, what do I do?" or "My macbook pro is making a whining
noise, what's wrong with it?" can yield significantly better responses
than context free response from LLMs.

### Testing

Run the following using the example document from the [`unstructured`
repo](https://github.com/Unstructured-IO/unstructured/tree/main/example-docs).

```python
from langchain.document_loaders.image import UnstructuredImageLoader

loader = UnstructuredImageLoader("layout-parser-paper-fast.jpg")
loader.load()

201ecdc9ee fix run and exec_run default commands, actually use gVisor
- run and exec_run need a separate default command. Run usually executes
  a script while exec_run simulates an interactive session. The image
  templates and run funcs have been upgraded to handle both
  types of commands.

- test: make docker tests run when docker is installed and docker lib
  avaialble.
  - test that runsc runtime is used by default when gVisor is installed.
    (manually removing gVisor skips the test)

Hi there! Thank you for even being interested in contributing to LangChain.
As an open source project in a rapidly developing field, we are extremely open
to contributions, whether they be in the form of new features, improved infra, better documentation, or bug fixes.
## 🗺️ Guidelines
### 👩‍💻 Contributing Code
to contributions, whether it be in the form of a new feature, improved infra, or better documentation.
To contribute to this project, please follow a ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow.
Please do not try to push directly to this repo unless you are maintainer.
Please follow the checked-in pull request template when opening pull requests. Note related issues and tag relevant
maintainers.
Pull requests cannot land without passing the formatting, linting and testing checks first. See
[Common Tasks](#-common-tasks) for how to run these checks locally.
It's essential that we maintain great documentation and testing. If you:
- Fix a bug
- Add a relevant unit or integration test when possible. These live in `tests/unit_tests` and `tests/integration_tests`.
- Make an improvement
- Update any affected example notebooks and documentation. These lives in `docs`.
- Update unit and integration tests when relevant.
- Add a feature
- Add a demo notebook in `docs/modules`.
- Add unit and integration tests.
We're a small, building-oriented team. If there's something you'd like to add or change, opening a pull request is the
best way to get our attention.
## 🗺Contributing Guidelines
### 🚩GitHub Issues
Our [issues](https://github.com/hwchase17/langchain/issues) page is kept up to date
with bugs, improvements, and feature requests.
with bugs, improvements, and feature requests. There is a taxonomy of labels to help
with sorting and discovery of issues of interest. These include:

- llms: related to LLM wrappers/tooling/infra.
- chains
- utilities: related to different types of utilities to integrate with (Python, SQL, etc.).
- agents
- memory
- applications: related to example applications to build
If you start working on an issue, please assign it to yourself.
If you are adding an issue, please try to keep it focused on a single, modular bug/improvement/feature.
If two issues are related, or blocking, please link them rather than combining them.
If you are adding an issue, please try to keep it focused on a single modular bug/improvement/feature.
If the two issues are related, or blocking, please link them rather than keep them as one single one.
We will try to keep these issues as up to date as possible, though
with the rapid rate of develop in this field some may get out of date.
If you notice this happening, please let us know.

### 🙋Getting Help
Our goal is to have the simplest developer setup possible. Should you experience any difficulty getting setup, please
contact a maintainer! Not only do we want to help get you unblocked, but we also want to make sure that the process is
smooth for future contributors.
Although we try to have a developer setup to make it as easy as possible for others to contribute (see below)
it is possible that some pain point may arise around environment setup, linting, documentation, or other.
Should that occur, please contact a maintainer! Not only do we want to help get you unblocked,
but we also want to make sure that the process is smooth for future contributors.
In a similar vein, we do enforce certain linting, formatting, and documentation standards in the codebase.
If you are finding these difficult (or even just annoying) to work with, feel free to contact a maintainer for help -
we do not want these to get in the way of getting good code into the codebase.

## 🚀 Quick Start
### 🏭Release process
As of now, LangChain has an ad hoc release process: releases are cut with high frequency via by
a developer and published to [PyPI](https://pypi.org/project/langchain/).
LangChain follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).
If your contribution has made its way into a release, we will want to give you credit on Twitter (only if you want though)!
If you have a Twitter account you would like us to mention, please let us know in the PR or in another manner.
## 🚀Quick Start
This project uses [Poetry](https://python-poetry.org/) as a dependency manager. Check out Poetry's [documentation on how to install it](https://python-poetry.org/docs/#installation) on your system before proceeding.

This will install all requirements for running the package, examples, linting, formatting, tests, and coverage. Note the `-E all` flag will install all optional dependencies necessary for integration testing.
❗Note: If you're running Poetry 1.4.1 and receive a `WheelFileValidationError` for `debugpy` during installation, you can try either downgrading to Poetry 1.4.0 or disabling "modern installation" (`poetry config installer.modern-installation false`) and re-install requirements.

## 🏭 Release Process
As of now, LangChain has an ad hoc release process: releases are cut with high frequency by
a developer and published to [PyPI](https://pypi.org/project/langchain/).
LangChain follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).
### 🌟 Recognition
If your contribution has made its way into a release, we will want to give you credit on Twitter (only if you want though)!
If you have a Twitter account you would like us to mention, please let us know in the PR or in another manner.

# 🦜️🔗 LangChain
# 🦜️🔗 LangChain - Docker
⚡ Building applications with LLMs through composability ⚡
WIP: This is a fork of langchain focused on implementing a docker warpper and
toolchain. The goal is to make it easy to use LLM chains running inside a
container, build custom docker based tools and let agents run arbitrary
untrusted code inside.

- Creating a toolchain for building docker based LLM tools.
- Building agents that can run arbitrary untrusted code inside a container.
## Quick Install
`pip install langchain`
or
`conda install langchain -c conda-forge`
## 🤔 What is this?
Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. However, using these LLMs in isolation is often insufficient for creating a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.

# Deployments
So, you've created a really cool chain - now what? How do you deploy it and make it easily shareable with the world?
This section covers several options for that. Note that these options are meant for quick deployment of prototypes and demos, not for production systems. If you need help with the deployment of a production system, please contact us directly.
What follows is a list of template GitHub repositories designed to be easily forked and modified to use your chain. This list is far from exhaustive, and we are EXTREMELY open to contributions here.
## [Streamlit](https://github.com/hwchase17/langchain-streamlit-template)
This repo serves as a template for how to deploy a LangChain with Streamlit.
It implements a chatbot interface.
It also contains instructions for how to deploy this app on the Streamlit platform.
## [Gradio (on Hugging Face)](https://github.com/hwchase17/langchain-gradio-template)
This repo serves as a template for how deploy a LangChain with Gradio.
It implements a chatbot interface, with a "Bring-Your-Own-Token" approach (nice for not wracking up big bills).
It also contains instructions for how to deploy this app on the Hugging Face platform.
This is heavily influenced by James Weaver's [excellent examples](https://huggingface.co/JavaFXpert).
## [Beam](https://github.com/slai-labs/get-beam/tree/main/examples/langchain-question-answering)
This repo serves as a template for how deploy a LangChain with [Beam](https://beam.cloud).
It implements a Question Answering app and contains instructions for deploying the app as a serverless REST API.
## [Vercel](https://github.com/homanp/vercel-langchain)
A minimal example on how to run LangChain on Vercel using Flask.
## [FastAPI + Vercel](https://github.com/msoedov/langcorn)
A minimal example on how to run LangChain on Vercel using FastAPI and LangCorn/Uvicorn.
## [Kinsta](https://github.com/kinsta/hello-world-langchain)
A minimal example on how to deploy LangChain to [Kinsta](https://kinsta.com) using Flask.
## [Fly.io](https://github.com/fly-apps/hello-fly-langchain)
A minimal example of how to deploy LangChain to [Fly.io](https://fly.io/) using Flask.
## [Digitalocean App Platform](https://github.com/homanp/digitalocean-langchain)
A minimal example on how to deploy LangChain to DigitalOcean App Platform.
## [Google Cloud Run](https://github.com/homanp/gcp-langchain)
A minimal example on how to deploy LangChain to Google Cloud Run.
## [SteamShip](https://github.com/steamship-core/steamship-langchain/)
This repository contains LangChain adapters for Steamship, enabling LangChain developers to rapidly deploy their apps on Steamship. This includes: production-ready endpoints, horizontal scaling across dependencies, persistent storage of app state, multi-tenancy support, etc.
## [Langchain-serve](https://github.com/jina-ai/langchain-serve)
This repository allows users to serve local chains and agents as RESTful, gRPC, or WebSocket APIs, thanks to [Jina](https://docs.jina.ai/). Deploy your chains & agents with ease and enjoy independent scaling, serverless and autoscaling APIs, as well as a Streamlit playground on Jina AI Cloud.
## [BentoML](https://github.com/ssheng/BentoChain)
This repository provides an example of how to deploy a LangChain application with [BentoML](https://github.com/bentoml/BentoML). BentoML is a framework that enables the containerization of machine learning applications as standard OCI images. BentoML also allows for the automatic generation of OpenAPI and gRPC endpoints. With BentoML, you can integrate models from all popular ML frameworks and deploy them as microservices running on the most optimal hardware and scaling independently.
## [Databutton](https://databutton.com/home?new-data-app=true)
These templates serve as examples of how to build, deploy, and share LangChain applications using Databutton. You can create user interfaces with Streamlit, automate tasks by scheduling Python code, and store files and data in the built-in store. Examples include a Chatbot interface with conversational memory, a Personal search engine, and a starter template for LangChain apps. Deploying and sharing is just one click away.

# Deployments
So you've made a really cool chain - now what? How do you deploy it and make it easily sharable with the world?
This section covers several options for that.
Note that these are meant as quick deployment options for prototypes and demos, and not for production systems.
If you are looking for help with deployment of a production system, please contact us directly.
What follows is a list of template GitHub repositories aimed that are intended to be
very easy to fork and modify to use your chain.
This is far from an exhaustive list of options, and we are EXTREMELY open to contributions here.
## [Streamlit](https://github.com/hwchase17/langchain-streamlit-template)
This repo serves as a template for how to deploy a LangChain with Streamlit.
It implements a chatbot interface.
It also contains instructions for how to deploy this app on the Streamlit platform.
## [Gradio (on Hugging Face)](https://github.com/hwchase17/langchain-gradio-template)
This repo serves as a template for how deploy a LangChain with Gradio.
It implements a chatbot interface, with a "Bring-Your-Own-Token" approach (nice for not wracking up big bills).
It also contains instructions for how to deploy this app on the Hugging Face platform.
This is heavily influenced by James Weaver's [excellent examples](https://huggingface.co/JavaFXpert).
## [Beam](https://github.com/slai-labs/get-beam/tree/main/examples/langchain-question-answering)
This repo serves as a template for how deploy a LangChain with [Beam](https://beam.cloud).
It implements a Question Answering app and contains instructions for deploying the app as a serverless REST API.
## [Vercel](https://github.com/homanp/vercel-langchain)
A minimal example on how to run LangChain on Vercel using Flask.
## [SteamShip](https://github.com/steamship-core/steamship-langchain/)
This repository contains LangChain adapters for Steamship, enabling LangChain developers to rapidly deploy their apps on Steamship.
This includes: production ready endpoints, horizontal scaling across dependencies, persistant storage of app state, multi-tenancy support, etc.

# SearxNG Search API
This page covers how to use the SearxNG search API within LangChain.
It is broken into two parts: installation and setup, and then references to the specific SearxNG API wrapper.
## Installation and Setup
- You can find a list of public SearxNG instances [here](https://searx.space/).
- It recommended to use a self-hosted instance to avoid abuse on the public instances. Also note that public instances often have a limit on the number of requests.
- To run a self-hosted instance see [this page](https://searxng.github.io/searxng/admin/installation.html) for more information.
- To use the tool you need to provide the searx host url by:
1. passing the named parameter `searx_host` when creating the instance.
2. exporting the environment variable `SEARXNG_HOST`.
## Wrappers
### Utility
You can use the wrapper to get results from a SearxNG instance.
```python
from langchain.utilities import SearxSearchWrapper
```
### Tool
You can also easily load this wrapper as a Tool (to use with an Agent).
You can do this with:
```python

`unstructured` wrappers.
## Installation and Setup
If you are using a loader that runs locally, use the following steps to get `unstructured` and
its dependencies running locally.
- Install the Python SDK with `pip install "unstructured[local-inference]"`
- Install the following system dependencies if they are not already available on your system.
Depending on what document types you're parsing, you may not need all of these.
- `libmagic-dev` (filetype detection)
- `poppler-utils` (images and PDFs)
- `tesseract-ocr`(images and PDFs)
- `libreoffice` (MS Office docs)
- `pandoc` (EPUBs)
- If you are parsing PDFs using the `"hi_res"` strategy, run the following to install the `detectron2` model, which
- `libmagic-dev`
- `poppler-utils`
- `tesseract-ocr`
- `libreoffice`
- If you are parsing PDFs, run the following to install the `detectron2` model, which
`unstructured` uses for layout detection:
- `pip install "detectron2@git+https://github.com/facebookresearch/detectron2.git@e2ce8dc#egg=detectron2"`
- If `detectron2` is not installed, `unstructured` will fallback to processing PDFs
using the `"fast"` strategy, which uses `pdfminer` directly and doesn't require
`detectron2`.
If you want to get up and running with less set up, you can
simply run `pip install unstructured` and use `UnstructuredAPIFileLoader` or
`UnstructuredAPIFileIOLoader`. That will process your document using the hosted Unstructured API.
Note that currently (as of 1 May 2023) the Unstructured API is open, but it will soon require
an API. The [Unstructured documentation page](https://unstructured-io.github.io/) will have
instructions on how to generate an API key once they're available. Check out the instructions
[here](https://github.com/Unstructured-IO/unstructured-api#dizzy-instructions-for-using-the-docker-image)
if you'd like to self-host the Unstructured API or run it locally.

## Memory: Add State to Chains and Agents
`````{dropdown} Memory: Add state to chains and agents
So far, all the chains and agents we've gone through have been stateless. But often, you may want a chain or agent to have some concept of "memory" so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of "short-term memory". On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of "long-term memory". For more concrete ideas on the latter, see this [awesome paper](https://memprompt.com/).

## Building a Language Model Application: Chat Models
Similarly, you can use chat models instead of LLMs. Chat models are a variation on language models. While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a "text in, text out" API, they expose an interface where "chat messages" are the inputs and outputs.
Chat model APIs are fairly new, so we are still figuring out the correct abstractions.
## Get Message Completions from a Chat Model
You can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are `AIMessage`, `HumanMessage`, `SystemMessage`, and `ChatMessage` -- `ChatMessage` takes in an arbitrary role parameter. Most of the time, you'll just be dealing with `HumanMessage`, `AIMessage`, and `SystemMessage`.
```python
from langchain.chat_models import ChatOpenAI
from langchain.schema import (
AIMessage,
HumanMessage,
SystemMessage
)
chat = ChatOpenAI(temperature=0)
```
You can get completions by passing in a single message.
```python
chat([HumanMessage(content="Translate this sentence from English to French. I love programming.")])
# -> AIMessage(content="J'aime programmer.", additional_kwargs={})
```
You can also pass in multiple messages for OpenAI's gpt-3.5-turbo and gpt-4 models.
```python
messages = [
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="I love programming.")
]
chat(messages)
# -> AIMessage(content="J'aime programmer.", additional_kwargs={})
```
You can go one step further and generate completions for multiple sets of messages using `generate`. This returns an `LLMResult` with an additional `message` parameter:
```python
batch_messages = [
[
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="I love programming.")
],
[
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="I love artificial intelligence.")
],
]
result = chat.generate(batch_messages)
result
# -> LLMResult(generations=[[ChatGeneration(text="J'aime programmer.", generation_info=None, message=AIMessage(content="J'aime programmer.", additional_kwargs={}))], [ChatGeneration(text="J'aime l'intelligence artificielle.", generation_info=None, message=AIMessage(content="J'aime l'intelligence artificielle.", additional_kwargs={}))]], llm_output={'token_usage': {'prompt_tokens': 57, 'completion_tokens': 20, 'total_tokens': 77}})
```
You can recover things like token usage from this LLMResult:
```
result.llm_output['token_usage']
# -> {'prompt_tokens': 57, 'completion_tokens': 20, 'total_tokens': 77}
```
## Chat Prompt Templates
Similar to LLMs, you can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplate`s. You can use `ChatPromptTemplate`'s `format_prompt` -- this returns a `PromptValue`, which you can convert to a string or `Message` object, depending on whether you want to use the formatted value as input to an llm or chat model.
For convenience, there is a `from_template` method exposed on the template. If you were to use this template, this is what it would look like:
```python
from langchain.chat_models import ChatOpenAI
from langchain.prompts.chat import (
ChatPromptTemplate,
SystemMessagePromptTemplate,
HumanMessagePromptTemplate,
)
chat = ChatOpenAI(temperature=0)
template = "You are a helpful assistant that translates {input_language} to {output_language}."
system_message_prompt = SystemMessagePromptTemplate.from_template(template)
human_template = "{text}"
human_message_prompt = HumanMessagePromptTemplate.from_template(human_template)
chat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, human_message_prompt])
# get a chat completion from the formatted messages
chat(chat_prompt.format_prompt(input_language="English", output_language="French", text="I love programming.").to_messages())
# -> AIMessage(content="J'aime programmer.", additional_kwargs={})
```
## Chains with Chat Models
The `LLMChain` discussed in the above section can be used with chat models as well:
```python
from langchain.chat_models import ChatOpenAI
from langchain import LLMChain
from langchain.prompts.chat import (
ChatPromptTemplate,
SystemMessagePromptTemplate,
HumanMessagePromptTemplate,
)
chat = ChatOpenAI(temperature=0)
template = "You are a helpful assistant that translates {input_language} to {output_language}."
system_message_prompt = SystemMessagePromptTemplate.from_template(template)
human_template = "{text}"
human_message_prompt = HumanMessagePromptTemplate.from_template(human_template)
chat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, human_message_prompt])
chain = LLMChain(llm=chat, prompt=chat_prompt)
chain.run(input_language="English", output_language="French", text="I love programming.")
# -> "J'aime programmer."
```
## Agents with Chat Models
Agents can also be used with chat models, you can initialize one using `AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION` as the agent type.
```python
from langchain.agents import load_tools
from langchain.agents import initialize_agent
from langchain.agents import AgentType
from langchain.chat_models import ChatOpenAI
from langchain.llms import OpenAI
# First, let's load the language model we're going to use to control the agent.
chat = ChatOpenAI(temperature=0)
# Next, let's load some tools to use. Note that the `llm-math` tool uses an LLM, so we need to pass that in.
llm = OpenAI(temperature=0)
tools = load_tools(["serpapi", "llm-math"], llm=llm)
# Finally, let's initialize an agent with the tools, the language model, and the type of agent we want to use.
agent = initialize_agent(tools, chat, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True)
# Now let's test it out!
agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
```
```pycon
> Entering new AgentExecutor chain...
Thought: I need to use a search engine to find Olivia Wilde's boyfriend and a calculator to raise his age to the 0.23 power.
Action:
{
"action": "Search",
"action_input": "Olivia Wilde boyfriend"
}
Observation: Sudeikis and Wilde's relationship ended in November 2020. Wilde was publicly served with court documents regarding child custody while she was presenting Don't Worry Darling at CinemaCon 2022. In January 2021, Wilde began dating singer Harry Styles after meeting during the filming of Don't Worry Darling.
Thought:I need to use a search engine to find Harry Styles' current age.
Action:
{

"action_input": "Harry Styles age"

"action_input": "29^0.23"
}

Thought:I now know the final answer.
Final Answer: 2.169459462491557
> Finished chain.
'2.169459462491557'
```
## Memory: Add State to Chains and Agents
You can use Memory with chains and agents initialized with chat models. The main difference between this and Memory for LLMs is that rather than trying to condense all previous messages into a string, we can keep them as their own unique memory object.
```python
from langchain.prompts import (
ChatPromptTemplate,
MessagesPlaceholder,
SystemMessagePromptTemplate,
HumanMessagePromptTemplate
)
from langchain.chains import ConversationChain
from langchain.chat_models import ChatOpenAI
from langchain.memory import ConversationBufferMemory
prompt = ChatPromptTemplate.from_messages([
SystemMessagePromptTemplate.from_template("The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know."),
MessagesPlaceholder(variable_name="history"),
HumanMessagePromptTemplate.from_template("{input}")
])
llm = ChatOpenAI(temperature=0)
memory = ConversationBufferMemory(return_messages=True)
conversation = ConversationChain(memory=memory, prompt=prompt, llm=llm)
conversation.predict(input="Hi there!")
# -> 'Hello! How can I assist you today?'
conversation.predict(input="I'm doing well! Just having a conversation with an AI.")
# -> "That sounds like fun! I'm happy to chat with you. Is there anything specific you'd like to talk about?"
conversation.predict(input="Tell me about yourself.")
# -> "Sure! I am an AI language model created by OpenAI. I was trained on a large dataset of text from the internet, which allows me to understand and generate human-like language. I can answer questions, provide information, and even have conversations like this one. Is there anything else you'd like to know about me?"

Welcome to LangChain
==========================
| **LangChain** is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call out to a language model, but will also be:
1. *Data-aware*: connect a language model to other sources of data
2. *Agentic*: allow a language model to interact with its environment
Large language models (LLMs) are emerging as a transformative technology, enabling
developers to build applications that they previously could not.
But using these LLMs in isolation is often not enough to
create a truly powerful app - the real power comes when you are able to
combine them with other sources of computation or knowledge.
| The LangChain framework is designed around these principles.
This library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include:
| This is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see `here <https://docs.langchain.com/docs/>`_. For the JavaScript documentation, see `here <https://js.langchain.com/docs/>`_.
**❓ Question Answering over specific documents**
- `Documentation <./use_cases/question_answering.html>`_
- End-to-end Example: `Question Answering over Notion Database <https://github.com/hwchase17/notion-qa>`_
**💬 Chatbots**

Modules
-----------
| These modules are the core abstractions which we view as the building blocks of any LLM-powered application.
For each module LangChain provides standard, extendable interfaces. LangChain also provides external integrations and even end-to-end implementations for off-the-shelf use.
There are several main modules that LangChain provides support for.
For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.
These modules are, in increasing order of complexity:
| The docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.
| The modules are (from least to most complex):
- `Prompts <./modules/prompts.html>`_: This includes prompt management, prompt optimization, and prompt serialization.
- `Models <./modules/models.html>`_: Supported model types and integrations.
- `LLMs <./modules/llms.html>`_: This includes a generic interface for all LLMs, and common utilities for working with LLMs.
- `Prompts <./modules/prompts.html>`_: Prompt management, optimization, and serialization.
- `Document Loaders <./modules/document_loaders.html>`_: This includes a standard interface for loading documents, as well as specific integrations to all types of text data sources.
- `Memory <./modules/memory.html>`_: Memory refers to state that is persisted between calls of a chain/agent.
- `Utils <./modules/utils.html>`_: Language models are often more powerful when interacting with other sources of knowledge or computation. This can include Python REPLs, embeddings, search engines, and more. LangChain provides a large collection of common utils to use in your application.
- `Indexes <./modules/indexes.html>`_: Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.
- `Chains <./modules/chains.html>`_: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.
- `Chains <./modules/chains.html>`_: Chains are structured sequences of calls (to an LLM or to a different utility).
- `Indexes <./modules/indexes.html>`_: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.
- `Agents <./modules/agents.html>`_: An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.
- `Agents <./modules/agents.html>`_: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.
- `Memory <./modules/memory.html>`_: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.
- `Callbacks <./modules/callbacks/getting_started.html>`_: Callbacks let you log and stream the intermediate steps of any chain, making it easy to observe, debug, and evaluate the internals of an application.

Use Cases
----------
| Best practices and built-in implementations for common LangChain use cases:
The above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.
- `Autonomous Agents <./use_cases/autonomous_agents.html>`_: Autonomous agents are long-running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.
- `Agents <./use_cases/agents.html>`_: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.
- `Agent Simulations <./use_cases/agent_simulations.html>`_: Putting agents in a sandbox and observing how they interact with each other and react to events can be an effective way to evaluate their long-range reasoning and planning abilities.
- `Chatbots <./use_cases/chatbots.html>`_: Since language models are good at producing text, that makes them ideal for creating chatbots.
- `Personal Assistants <./use_cases/personal_assistants.html>`_: One of the primary LangChain use cases. Personal assistants need to take actions, remember interactions, and have knowledge about your data.
- `Data Augmented Generation <./use_cases/combine_docs.html>`_: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.
- `Question Answering <./use_cases/question_answering.html>`_: Another common LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.
- `Question Answering <./use_cases/question_answering.html>`_: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.
- `Chatbots <./use_cases/chatbots.html>`_: Language models love to chat, making this a very natural use of them.
- `Summarization <./use_cases/summarization.html>`_: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
- `Querying Tabular Data <./use_cases/tabular.html>`_: Recommended reading if you want to use language models to query structured data (CSVs, SQL, dataframes, etc).
- `Evaluation <./use_cases/evaluation.html>`_: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
- `Code Understanding <./use_cases/code.html>`_: Recommended reading if you want to use language models to analyze code.
- `Generate similar examples <./use_cases/generate_examples.html>`_: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.
- `Interacting with APIs <./use_cases/apis.html>`_: Enabling language models to interact with APIs is extremely powerful. It gives them access to up-to-date information and allows them to take actions.
- `Compare models <./use_cases/model_laboratory.html>`_: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.
- `Extraction <./use_cases/extraction.html>`_: Extract structured information from text.
- `Summarization <./use_cases/summarization.html>`_: Compressing longer documents. A type of Data-Augmented Generation.
- `Evaluation <./use_cases/evaluation.html>`_: Generative models are hard to evaluate with traditional metrics. One promising approach is to use language models themselves to do the evaluation.

# AnalyticDB
This page covers how to use the AnalyticDB ecosystem within LangChain.
### VectorStore
There exists a wrapper around AnalyticDB, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import AnalyticDB
```
For a more detailed walkthrough of the AnalyticDB wrapper, see [this notebook](../modules/indexes/vectorstores/examples/analyticdb.ipynb)

# Anyscale
This page covers how to use the Anyscale ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Anyscale wrappers.
## Installation and Setup
- Get an Anyscale Service URL, route and API key and set them as environment variables (`ANYSCALE_SERVICE_URL`,`ANYSCALE_SERVICE_ROUTE`, `ANYSCALE_SERVICE_TOKEN`).
- Please see [the Anyscale docs](https://docs.anyscale.com/productionize/services-v2/get-started) for more details.
## Wrappers
### LLM
There exists an Anyscale LLM wrapper, which you can access with
```python
from langchain.llms import Anyscale
```

# Apify
This page covers how to use [Apify](https://apify.com) within LangChain.
## Overview
Apify is a cloud platform for web scraping and data extraction,
which provides an [ecosystem](https://apify.com/store) of more than a thousand
ready-made apps called *Actors* for various scraping, crawling, and extraction use cases.
[![Apify Actors](../_static/ApifyActors.png)](https://apify.com/store)
This integration enables you run Actors on the Apify platform and load their results into LangChain to feed your vector
indexes with documents and data from the web, e.g. to generate answers from websites with documentation,
blogs, or knowledge bases.
## Installation and Setup
- Install the Apify API client for Python with `pip install apify-client`
- Get your [Apify API token](https://console.apify.com/account/integrations) and either set it as
an environment variable (`APIFY_API_TOKEN`) or pass it to the `ApifyWrapper` as `apify_api_token` in the constructor.
## Wrappers
### Utility
You can use the `ApifyWrapper` to run Actors on the Apify platform.
```python
from langchain.utilities import ApifyWrapper
```
For a more detailed walkthrough of this wrapper, see [this notebook](../modules/agents/tools/examples/apify.ipynb).
### Loader
You can also use our `ApifyDatasetLoader` to get data from Apify dataset.
```python
from langchain.document_loaders import ApifyDatasetLoader
```
For a more detailed walkthrough of this loader, see [this notebook](../modules/indexes/document_loaders/examples/apify_dataset.ipynb).

# Deep Lake
This page covers how to use the Deep Lake ecosystem within LangChain.
## Why Deep Lake?
- More than just a (multi-modal) vector store. You can later use the dataset to fine-tune your own LLM models.
- Not only stores embeddings, but also the original data with automatic version control.
- Truly serverless. Doesn't require another service and can be used with major cloud providers (AWS S3, GCS, etc.)

## Installation and Setup
- Install the Python package with `pip install deeplake`
## Wrappers
### VectorStore
There exists a wrapper around Deep Lake, a data lake for Deep Learning applications, allowing you to use it as a vector store (for now), whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import DeepLake
```

# Docugami
This page covers how to use [Docugami](https://docugami.com) within LangChain.
## What is Docugami?
Docugami converts business documents into a Document XML Knowledge Graph, generating forests of XML semantic trees representing entire documents. This is a rich representation that includes the semantic and structural characteristics of various chunks in the document as an XML tree.
## Quick start
1. Create a Docugami workspace: <a href="http://www.docugami.com">http://www.docugami.com</a> (free trials available)
2. Add your documents (PDF, DOCX or DOC) and allow Docugami to ingest and cluster them into sets of similar documents, e.g. NDAs, Lease Agreements, and Service Agreements. There is no fixed set of document types supported by the system, the clusters created depend on your particular documents, and you can [change the docset assignments](https://help.docugami.com/home/working-with-the-doc-sets-view) later.
3. Create an access token via the Developer Playground for your workspace. Detailed instructions: https://help.docugami.com/home/docugami-api
4. Explore the Docugami API at <a href="https://api-docs.docugami.com">https://api-docs.docugami.com</a> to get a list of your processed docset IDs, or just the document IDs for a particular docset.
6. Use the DocugamiLoader as detailed in [this notebook](../modules/indexes/document_loaders/examples/docugami.ipynb), to get rich semantic chunks for your documents.
7. Optionally, build and publish one or more [reports or abstracts](https://help.docugami.com/home/reports). This helps Docugami improve the semantic XML with better tags based on your preferences, which are then added to the DocugamiLoader output as metadata. Use techniques like [self-querying retriever](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query_retriever.html) to do high accuracy Document QA.
# Advantages vs Other Chunking Techniques
Appropriate chunking of your documents is critical for retrieval from documents. Many chunking techniques exist, including simple ones that rely on whitespace and recursive chunk splitting based on character length. Docugami offers a different approach:
1. **Intelligent Chunking:** Docugami breaks down every document into a hierarchical semantic XML tree of chunks of varying sizes, from single words or numerical values to entire sections. These chunks follow the semantic contours of the document, providing a more meaningful representation than arbitrary length or simple whitespace-based chunking.
2. **Structured Representation:** In addition, the XML tree indicates the structural contours of every document, using attributes denoting headings, paragraphs, lists, tables, and other common elements, and does that consistently across all supported document formats, such as scanned PDFs or DOCX files. It appropriately handles long-form document characteristics like page headers/footers or multi-column flows for clean text extraction.
3. **Semantic Annotations:** Chunks are annotated with semantic tags that are coherent across the document set, facilitating consistent hierarchical queries across multiple documents, even if they are written and formatted differently. For example, in set of lease agreements, you can easily identify key provisions like the Landlord, Tenant, or Renewal Date, as well as more complex information such as the wording of any sub-lease provision or whether a specific jurisdiction has an exception section within a Termination Clause.
4. **Additional Metadata:** Chunks are also annotated with additional metadata, if a user has been using Docugami. This additional metadata can be used for high-accuracy Document QA without context window restrictions. See detailed code walk-through in [this notebook](../modules/indexes/document_loaders/examples/docugami.ipynb).

# GPT4All
This page covers how to use the `GPT4All` wrapper within LangChain. The tutorial is divided into two parts: installation and setup, followed by usage with an example.
## Installation and Setup
- Install the Python package with `pip install pyllamacpp`
- Download a [GPT4All model](https://github.com/nomic-ai/pyllamacpp#supported-model) and place it in your desired directory
## Usage
### GPT4All
To use the GPT4All wrapper, you need to provide the path to the pre-trained model file and the model's configuration.
```python
from langchain.llms import GPT4All
# Instantiate the model. Callbacks support token-wise streaming
model = GPT4All(model="./models/gpt4all-model.bin", n_ctx=512, n_threads=8)
# Generate text
response = model("Once upon a time, ")
```
You can also customize the generation parameters, such as n_predict, temp, top_p, top_k, and others.
To stream the model's predictions, add in a CallbackManager.
```python
from langchain.llms import GPT4All
from langchain.callbacks.streaming_stdout import StreamingStdOutCallbackHandler
# There are many CallbackHandlers supported, such as
# from langchain.callbacks.streamlit import StreamlitCallbackHandler
callbacks = [StreamingStdOutCallbackHandler()]
model = GPT4All(model="./models/gpt4all-model.bin", n_ctx=512, n_threads=8)
# Generate text. Tokens are streamed through the callback manager.
model("Once upon a time, ", callbacks=callbacks)
```
## Model File
You can find links to model file downloads in the [pyllamacpp](https://github.com/nomic-ai/pyllamacpp) repository.

# Qdrant
This page covers how to use the Qdrant ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Qdrant wrappers.
## Installation and Setup
- Install the Python SDK with `pip install qdrant-client`
## Wrappers
### VectorStore
There exists a wrapper around Qdrant indexes, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import Qdrant
```
For a more detailed walkthrough of the Qdrant wrapper, see [this notebook](../modules/indexes/vectorstores/examples/qdrant.ipynb)

# Redis
This page covers how to use the [Redis](https://redis.com) ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Redis wrappers.
## Installation and Setup
- Install the Redis Python SDK with `pip install redis`
## Wrappers
### Cache
The Cache wrapper allows for [Redis](https://redis.io) to be used as a remote, low-latency, in-memory cache for LLM prompts and responses.
#### Standard Cache
The standard cache is the Redis bread & butter of use case in production for both [open source](https://redis.io) and [enterprise](https://redis.com) users globally.
To import this cache:
```python
from langchain.cache import RedisCache
```
To use this cache with your LLMs:
```python
import langchain
import redis
redis_client = redis.Redis.from_url(...)
langchain.llm_cache = RedisCache(redis_client)
```
#### Semantic Cache
Semantic caching allows users to retrieve cached prompts based on semantic similarity between the user input and previously cached results. Under the hood it blends Redis as both a cache and a vectorstore.
To import this cache:
```python
from langchain.cache import RedisSemanticCache
```
To use this cache with your LLMs:
```python
import langchain
import redis
# use any embedding provider...
from tests.integration_tests.vectorstores.fake_embeddings import FakeEmbeddings
redis_url = "redis://localhost:6379"
langchain.llm_cache = RedisSemanticCache(
embedding=FakeEmbeddings(),
redis_url=redis_url
)
```
### VectorStore
The vectorstore wrapper turns Redis into a low-latency [vector database](https://redis.com/solutions/use-cases/vector-database/) for semantic search or LLM content retrieval.
To import this vectorstore:
```python
from langchain.vectorstores import Redis
```
For a more detailed walkthrough of the Redis vectorstore wrapper, see [this notebook](../modules/indexes/vectorstores/examples/redis.ipynb).
### Retriever
The Redis vector store retriever wrapper generalizes the vectorstore class to perform low-latency document retrieval. To create the retriever, simply call `.as_retriever()` on the base vectorstore class.
### Memory
Redis can be used to persist LLM conversations.
#### Vector Store Retriever Memory
For a more detailed walkthrough of the `VectorStoreRetrieverMemory` wrapper, see [this notebook](../modules/memory/types/vectorstore_retriever_memory.ipynb).
#### Chat Message History Memory
For a detailed example of Redis to cache conversation message history, see [this notebook](../modules/memory/examples/redis_chat_message_history.ipynb).

# Replicate
This page covers how to run models on Replicate within LangChain.
## Installation and Setup
- Create a [Replicate](https://replicate.com) account. Get your API key and set it as an environment variable (`REPLICATE_API_TOKEN`)
- Install the [Replicate python client](https://github.com/replicate/replicate-python) with `pip install replicate`
## Calling a model
Find a model on the [Replicate explore page](https://replicate.com/explore), and then paste in the model name and version in this format: `owner-name/model-name:version`
For example, for this [dolly model](https://replicate.com/replicate/dolly-v2-12b), click on the API tab. The model name/version would be: `"replicate/dolly-v2-12b:ef0e1aefc61f8e096ebe4db6b2bacc297daf2ef6899f0f7e001ec445893500e5"`
Only the `model` param is required, but any other model parameters can also be passed in with the format `input={model_param: value, ...}`
For example, if we were running stable diffusion and wanted to change the image dimensions:
```
Replicate(model="stability-ai/stable-diffusion:db21e45d3f7023abc2a46ee38a23973f6dce16bb082a930b0c49861f96d1e5bf", input={'image_dimensions': '512x512'})
```
*Note that only the first output of a model will be returned.*
From here, we can initialize our model:
```python
llm = Replicate(model="replicate/dolly-v2-12b:ef0e1aefc61f8e096ebe4db6b2bacc297daf2ef6899f0f7e001ec445893500e5")
```
And run it:
```python
prompt = """
Answer the following yes/no question by reasoning step by step.
Can a dog drive a car?
"""
llm(prompt)
```
We can call any Replicate model (not just LLMs) using this syntax. For example, we can call [Stable Diffusion](https://replicate.com/stability-ai/stable-diffusion):
```python
text2image = Replicate(model="stability-ai/stable-diffusion:db21e45d3f7023abc2a46ee38a23973f6dce16bb082a930b0c49861f96d1e5bf", input={'image_dimensions':'512x512'})
image_output = text2image("A cat riding a motorcycle by Picasso")
```

# RWKV-4
This page covers how to use the `RWKV-4` wrapper within LangChain.
It is broken into two parts: installation and setup, and then usage with an example.
## Installation and Setup
- Install the Python package with `pip install rwkv`
- Install the tokenizer Python package with `pip install tokenizer`
- Download a [RWKV model](https://huggingface.co/BlinkDL/rwkv-4-raven/tree/main) and place it in your desired directory
- Download the [tokens file](https://raw.githubusercontent.com/BlinkDL/ChatRWKV/main/20B_tokenizer.json)
## Usage
### RWKV
To use the RWKV wrapper, you need to provide the path to the pre-trained model file and the tokenizer's configuration.
```python
from langchain.llms import RWKV
# Test the model
```python
def generate_prompt(instruction, input=None):
if input:
return f"""Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
# Instruction:
{instruction}
# Input:
{input}
# Response:
"""
else:
return f"""Below is an instruction that describes a task. Write a response that appropriately completes the request.
# Instruction:
{instruction}
# Response:
"""
model = RWKV(model="./models/RWKV-4-Raven-3B-v7-Eng-20230404-ctx4096.pth", strategy="cpu fp32", tokens_path="./rwkv/20B_tokenizer.json")
response = model(generate_prompt("Once upon a time, "))
```
## Model File
You can find links to model file downloads at the [RWKV-4-Raven](https://huggingface.co/BlinkDL/rwkv-4-raven/tree/main) repository.
### Rwkv-4 models -> recommended VRAM
```
RWKV VRAM
Model | 8bit | bf16/fp16 | fp32
14B | 16GB | 28GB | >50GB
7B | 8GB | 14GB | 28GB
3B | 2.8GB| 6GB | 12GB
1b5 | 1.3GB| 3GB | 6GB
```
See the [rwkv pip](https://pypi.org/project/rwkv/) page for more information about strategies, including streaming and cuda support.

# SearxNG Search API
This page covers how to use the SearxNG search API within LangChain.
It is broken into two parts: installation and setup, and then references to the specific SearxNG API wrapper.
## Installation and Setup
While it is possible to utilize the wrapper in conjunction with [public searx
instances](https://searx.space/) these instances frequently do not permit API
access (see note on output format below) and have limitations on the frequency
of requests. It is recommended to opt for a self-hosted instance instead.
### Self Hosted Instance:
See [this page](https://searxng.github.io/searxng/admin/installation.html) for installation instructions.
When you install SearxNG, the only active output format by default is the HTML format.
You need to activate the `json` format to use the API. This can be done by adding the following line to the `settings.yml` file:
```yaml
search:
formats:
- html
- json
```
You can make sure that the API is working by issuing a curl request to the API endpoint:
`curl -kLX GET --data-urlencode q='langchain' -d format=json http://localhost:8888`
This should return a JSON object with the results.
## Wrappers
### Utility
To use the wrapper we need to pass the host of the SearxNG instance to the wrapper with:
1. the named parameter `searx_host` when creating the instance.
2. exporting the environment variable `SEARXNG_HOST`.
You can use the wrapper to get results from a SearxNG instance.
```python
from langchain.utilities import SearxSearchWrapper
s = SearxSearchWrapper(searx_host="http://localhost:8888")
s.run("what is a large language model?")
```
### Tool
You can also load this wrapper as a Tool (to use with an Agent).
You can do this with:
```python
from langchain.agents import load_tools
tools = load_tools(["searx-search"],
searx_host="http://localhost:8888",
engines=["github"])
```
Note that we could _optionally_ pass custom engines to use.
If you want to obtain results with metadata as *json* you can use:
```python
tools = load_tools(["searx-search-results-json"],
searx_host="http://localhost:8888",
num_results=5)
```
For more information on tools, see [this page](../modules/agents/tools/getting_started.md)

# Tair
This page covers how to use the Tair ecosystem within LangChain.
## Installation and Setup
Install Tair Python SDK with `pip install tair`.
## Wrappers
### VectorStore
There exists a wrapper around TairVector, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import Tair
```
For a more detailed walkthrough of the Tair wrapper, see [this notebook](../modules/indexes/vectorstores/examples/tair.ipynb)

# Yeager.ai
This page covers how to use [Yeager.ai](https://yeager.ai) to generate LangChain tools and agents.
## What is Yeager.ai?
Yeager.ai is an ecosystem designed to simplify the process of creating AI agents and tools.
It features yAgents, a No-code LangChain Agent Builder, which enables users to build, test, and deploy AI solutions with ease. Leveraging the LangChain framework, yAgents allows seamless integration with various language models and resources, making it suitable for developers, researchers, and AI enthusiasts across diverse applications.
## yAgents
Low code generative agent designed to help you build, prototype, and deploy Langchain tools with ease.
### How to use?
```
pip install yeagerai-agent
yeagerai-agent
```
Go to http://127.0.0.1:7860
This will install the necessary dependencies and set up yAgents on your system. After the first run, yAgents will create a .env file where you can input your OpenAI API key. You can do the same directly from the Gradio interface under the tab "Settings".
`OPENAI_API_KEY=<your_openai_api_key_here>`
We recommend using GPT-4,. However, the tool can also work with GPT-3 if the problem is broken down sufficiently.
### Creating and Executing Tools with yAgents
yAgents makes it easy to create and execute AI-powered tools. Here's a brief overview of the process:
1. Create a tool: To create a tool, provide a natural language prompt to yAgents. The prompt should clearly describe the tool's purpose and functionality. For example:
`create a tool that returns the n-th prime number`
2. Load the tool into the toolkit: To load a tool into yAgents, simply provide a command to yAgents that says so. For example:
`load the tool that you just created it into your toolkit`
3. Execute the tool: To run a tool or agent, simply provide a command to yAgents that includes the name of the tool and any required parameters. For example:
`generate the 50th prime number`
You can see a video of how it works [here](https://www.youtube.com/watch?v=KA5hCM3RaWE).
As you become more familiar with yAgents, you can create more advanced tools and agents to automate your work and enhance your productivity.
For more information, see [yAgents' Github](https://github.com/yeagerai/yeagerai-agent) or our [docs](https://yeagerai.gitbook.io/docs/general/welcome-to-yeager.ai)

# Zilliz
This page covers how to use the Zilliz Cloud ecosystem within LangChain.
Zilliz uses the Milvus integration.
It is broken into two parts: installation and setup, and then references to specific Milvus wrappers.
## Installation and Setup
- Install the Python SDK with `pip install pymilvus`
## Wrappers
### VectorStore
There exists a wrapper around Zilliz indexes, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores import Milvus
```
For a more detailed walkthrough of the Miluvs wrapper, see [this notebook](../modules/indexes/vectorstores/examples/zilliz.ipynb)
