# Using Docker
|
||||
|
||||
To quickly get started, run the command `make docker`.
|
||||
|
||||
If docker is installed the Makefile will export extra targets in the fomrat `docker.*` to build and run the docker image. Type `make` for a list of available tasks.
|
||||
|
||||
There is a basic `docker-compose.yml` in the docker directory.
|
||||
|
||||
## Building the development image
|
||||
|
||||
Using `make docker` will build the dev image if it does not exist, then drops
|
||||
you inside the container with the langchain environment available in the shell.
|
||||
|
||||
### Customizing the image and installed dependencies
|
||||
|
||||
The image is built with a default python version and all extras and dev
|
||||
dependencies. It can be customized by changing the variables in the [.env](/docker/.env)
|
||||
file.
|
||||
|
||||
If you don't need all the `extra` dependencies a slimmer image can be obtained by
|
||||
commenting out `POETRY_EXTRA_PACKAGES` in the [.env](docker/.env) file.
|
||||
|
||||
### Image caching
|
||||
|
||||
The Dockerfile is optimized to cache the poetry install step. A rebuild is triggered when there a change to the source code.
|
||||
|
||||
## Example Usage
|
||||
|
||||
All commands from langchain's python environment are available by default in the container.
|
||||
|
||||
A few examples:
|
||||
```bash
|
||||
# run jupyter notebook
|
||||
docker run --rm -it IMG jupyter notebook
|
||||
|
||||
# run ipython
|
||||
docker run --rm -it IMG ipython
|
||||
|
||||
# start web server
|
||||
docker run --rm -p 8888:8888 IMG python -m http.server 8888
|
||||
```
|
||||
|
||||
## Testing / Linting
|
||||
|
||||
Tests and lints are run using your local source directory that is mounted on the volume /src.
|
||||
|
||||
Run unit tests in the container with `make docker.test`.
|
||||
|
||||
Run the linting and formatting checks with `make docker.lint`.
|
||||
|
||||
Note: this task can run in parallel using `make -j4 docker.lint`.

# 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.
|
||||
|
||||

### VectorStore
|
||||
|
||||
There exists a wrapper around the Atlas neural database, allowing you to use it as a vectorstore.
|
||||
This vectorstore also gives you full access to the underlying AtlasProject object, which will allow you to use the full range of Atlas map interactions, such as bulk tagging and automatic topic modeling.

# Banana
|
||||
|
||||
This page covers how to use the Banana ecosystem within LangChain.
|
||||
It is broken into two parts: installation and setup, and then references to specific Banana wrappers.
|
||||
|
||||
## Installation and Setup
|
||||
|
||||
- Install with `pip3 install banana-dev`
|
||||
- Get an Banana api key and set it as an environment variable (`BANANA_API_KEY`)
|
||||
|
||||
## Define your Banana Template
|
||||
|
||||
If you want to use an available language model template you can find one [here](https://app.banana.dev/templates/conceptofmind/serverless-template-palmyra-base).
|
||||
This template uses the Palmyra-Base model by [Writer](https://writer.com/product/api/).
|
||||
You can check out an example Banana repository [here](https://github.com/conceptofmind/serverless-template-palmyra-base).
|
||||
|
||||
## Build the Banana app
|
||||
|
||||
Banana Apps must include the "output" key in the return json.
|
||||
There is a rigid response structure.
|
||||
|
||||
```python
|
||||
# Return the results as a dictionary
|
||||
result = {'output': result}
|
||||
```
|
||||
|
||||
An example inference function would be:
|
||||
|
||||
```python
|
||||
def inference(model_inputs:dict) -> dict:
|
||||
global model
|
||||
global tokenizer
|
||||
|
||||
# Parse out your arguments
|
||||
prompt = model_inputs.get('prompt', None)
|
||||
if prompt == None:
|
||||
return {'message': "No prompt provided"}
|
||||
|
||||
# Run the model
|
||||
input_ids = tokenizer.encode(prompt, return_tensors='pt').cuda()
|
||||
output = model.generate(
|
||||
input_ids,
|
||||
max_length=100,
|
||||
do_sample=True,
|
||||
top_k=50,
|
||||
top_p=0.95,
|
||||
num_return_sequences=1,
|
||||
temperature=0.9,
|
||||
early_stopping=True,
|
||||
no_repeat_ngram_size=3,
|
||||
num_beams=5,
|
||||
length_penalty=1.5,
|
||||
repetition_penalty=1.5,
|
||||
bad_words_ids=[[tokenizer.encode(' ', add_prefix_space=True)[0]]]
|
||||
)
|
||||
|
||||
result = tokenizer.decode(output[0], skip_special_tokens=True)
|
||||
# Return the results as a dictionary
|
||||
result = {'output': result}
|
||||
return result
|
||||
```
|
||||
|
||||

||||
|
||||
This page covers how to use the [Serper](https://serper.dev) Google Search API within LangChain. Serper is a low-cost Google Search API that can be used to add answer box, knowledge graph, and organic results data from Google Search.
|
||||
It is broken into two parts: setup, and then references to the specific Google Serper wrapper.
|
||||
|
||||
## Setup
|
||||
- Go to [serper.dev](https://serper.dev) to sign up for a free account
|
||||
- Get the api key and set it as an environment variable (`SERPER_API_KEY`)
|
||||
|
||||
## Wrappers
|
||||
|
||||
### Utility
|
||||
|
||||
There exists a GoogleSerperAPIWrapper utility which wraps this API. To import this utility:
|
||||
|
||||
```python
|
||||
from langchain.utilities import GoogleSerperAPIWrapper
|
||||
```
|
||||
|
||||
You can use it as part of a Self Ask chain:
|
||||
|
||||
```python
|
||||
from langchain.utilities import GoogleSerperAPIWrapper
|
||||
from langchain.llms.openai import OpenAI
|
||||
from langchain.agents import initialize_agent, Tool
|
||||
|
||||
import os
|
||||
|
||||
os.environ["SERPER_API_KEY"] = ""
|
||||
os.environ['OPENAI_API_KEY'] = ""
|
||||
|
||||
llm = OpenAI(temperature=0)
|
||||
search = GoogleSerperAPIWrapper()
|
||||
tools = [
|
||||
Tool(
|
||||
name="Intermediate Answer",
|
||||
func=search.run
|
||||
)
|
||||
]
|
||||
|
||||
self_ask_with_search = initialize_agent(tools, llm, agent="self-ask-with-search", verbose=True)
|
||||
self_ask_with_search.run("What is the hometown of the reigning men's U.S. Open champion?")
|
||||
```
|
||||
|
||||
#### Output
|
||||
```
|
||||
Entering new AgentExecutor chain...
|
||||
Yes.
|
||||
Follow up: Who is the reigning men's U.S. Open champion?
|
||||
Intermediate answer: Current champions Carlos Alcaraz, 2022 men's singles champion.
|
||||
Follow up: Where is Carlos Alcaraz from?
|
||||
Intermediate answer: El Palmar, Spain
|
||||
So the final answer is: El Palmar, Spain
|
||||
|
||||
> Finished chain.
|
||||
|
||||
'El Palmar, Spain'
|
||||
```
|
||||
|
||||
For a more detailed walkthrough of this wrapper, see [this notebook](../modules/utils/examples/google_serper.ipynb).
|
||||
|
||||
### Tool
|
||||
|
||||
You can also easily 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(["google-serper"])
|
||||
```

# Graphsignal
|
||||
|
||||
This page covers how to use the Graphsignal to trace and monitor LangChain.
|
||||
|
||||
## Installation and Setup
|
||||
|
||||
- Install the Python library with `pip install graphsignal`
|
||||
- Create free Graphsignal account [here](https://graphsignal.com)
|
||||
- Get an API key and set it as an environment variable (`GRAPHSIGNAL_API_KEY`)
|
||||
|
||||
## Tracing and Monitoring
|
||||
|
||||
Graphsignal automatically instruments and starts tracing and monitoring chains. Traces, metrics and errors are then available in your [Graphsignal dashboard](https://app.graphsignal.com/). No prompts or other sensitive data are sent to Graphsignal cloud, only statistics and metadata.
|
||||
|
||||
Initialize the tracer by providing a deployment name:
|
||||
|
||||
```python
|
||||
import graphsignal
|
||||
|
||||
graphsignal.configure(deployment='my-langchain-app-prod')
|
||||
```
|
||||
|
||||
In order to trace full runs and see a breakdown by chains and tools, you can wrap the calling routine or use a decorator:
|
||||
|
||||
```python
|
||||
with graphsignal.start_trace('my-chain'):
|
||||
chain.run("some initial text")
|
||||
```
|
||||
|
||||
Optionally, enable profiling to record function-level statistics for each trace.
|
||||
|
||||
```python
|
||||
with graphsignal.start_trace(
|
||||
'my-chain', options=graphsignal.TraceOptions(enable_profiling=True)):
|
||||
chain.run("some initial text")
|
||||
```
|
||||
|
||||

# Runhouse
|
||||
|
||||
This page covers how to use the [Runhouse](https://github.com/run-house/runhouse) ecosystem within LangChain.
|
||||
It is broken into three parts: installation and setup, LLMs, and Embeddings.
|
||||
|
||||
## Installation and Setup
|
||||
- Install the Python SDK with `pip install runhouse`
|
||||
- If you'd like to use on-demand cluster, check your cloud credentials with `sky check`
|
||||
|
||||
## Self-hosted LLMs
|
||||
For a basic self-hosted LLM, you can use the `SelfHostedHuggingFaceLLM` class. For more
|
||||
custom LLMs, you can use the `SelfHostedPipeline` parent class.
|
||||
|
||||
```python
|
||||
from langchain.llms import SelfHostedPipeline, SelfHostedHuggingFaceLLM
|
||||
```
|
||||
|
||||
For a more detailed walkthrough of the Self-hosted LLMs, see [this notebook](../modules/llms/integrations/self_hosted_examples.ipynb)
|
||||
|
||||
## Self-hosted Embeddings
|
||||
There are several ways to use self-hosted embeddings with LangChain via Runhouse.
|
||||
|
||||
For a basic self-hosted embedding from a Hugging Face Transformers model, you can use
|
||||
the `SelfHostedEmbedding` class.
|
||||
```python
|
||||
from langchain.llms import SelfHostedPipeline, SelfHostedHuggingFaceLLM
|
||||
```
|
||||
|
||||
For a more detailed walkthrough of the Self-hosted Embeddings, see [this notebook](../modules/indexes/examples/embeddings.ipynb)

# 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
|
||||
from langchain.agents import load_tools
|
||||
tools = load_tools(["searx-search"], searx_host="https://searx.example.com")
|
||||
```

# Unstructured
|
||||
|
||||
This page covers how to use the [`unstructured`](https://github.com/Unstructured-IO/unstructured)
|
||||
ecosystem within LangChain. The `unstructured` package from
|
||||
[Unstructured.IO](https://www.unstructured.io/) extracts clean text from raw source documents like
|
||||
PDFs and Word documents.
|
||||
|
||||
|
||||
This page is broken into two parts: installation and setup, and then references to specific
|
||||
`unstructured` wrappers.
|
||||
|
||||
## Installation and Setup
|
||||
- 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`
|
||||
- `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@v0.6#egg=detectron2"`
|
||||
|
||||
## Wrappers
|
||||
|
||||
### Data Loaders
|
||||
|
||||
The primary `unstructured` wrappers within `langchain` are data loaders. The following
|
||||
shows how to use the most basic unstructured data loader. There are other file-specific
|
||||
data loaders available in the `langchain.document_loaders` module.
|
||||
|
||||
```python
|
||||
from langchain.document_loaders import UnstructuredFileLoader
|
||||
|
||||
loader = UnstructuredFileLoader("state_of_the_union.txt")
|
||||
loader.load()
|
||||
```
|
||||
|
||||
If you instantiate the loader with `UnstructuredFileLoader(mode="elements")`, the loader
|
||||
will track additional metadata like the page number and text type (i.e. title, narrative text)
|
||||
when that information is available.

# Core Concepts
|
||||
|
||||
This section goes over the core concepts of LangChain.
|
||||
Understanding these will go a long way in helping you understand the codebase and how to construct chains.
|
||||
|
||||
## PromptTemplates
|
||||
PromptTemplates generically have a `format` method that takes in variables and returns a formatted string.
|
||||
The most simple implementation of this is to have a template string with some variables in it, and then format it with the incoming variables.
|
||||
More complex iterations dynamically construct the template string from few shot examples, etc.
|
||||
|
||||
For a more detailed explanation of how LangChain approaches prompts and prompt templates, see [here](/examples/prompts/prompt_management).
|
||||
|
||||
## LLMs
|
||||
Wrappers around Large Language Models (in particular, the `generate` ability of large language models) are some of the core functionality of LangChain.
|
||||
These wrappers are classes that are callable: they take in an input string, and return the generated output string.
|
||||
|
||||
## Embeddings
|
||||
These classes are very similar to the LLM classes in that they are wrappers around models,
|
||||
but rather than return a string they return an embedding (list of floats). This are particularly useful when
|
||||
implementing semantic search functionality. They expose separate methods for embedding queries versus embedding documents.
|
||||
|
||||
## Vectorstores
|
||||
These are datastores that store documents. They expose a method for passing in a string and finding similar documents.
|
||||
|
||||
## Chains
|
||||
These are pipelines that combine multiple of the above ideas.
|
||||
They vary greatly in complexity and are combination of generic, highly configurable pipelines and more narrow (but usually more complex) pipelines.
|
||||
|
||||
## Agents
|
||||
As opposed to a chain, whether the steps to be taken are known ahead of time, agents
|
||||
use an LLM to determine which tools to call and in what order.

# Setting up your environment
|
||||
|
||||
Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
|
||||
There are two components to setting this up, installing the correct python packages and setting the right environment variables.
|
||||
|
||||
## Python packages
|
||||
The python package needed varies based on the integration. See the list of integrations for details.
|
||||
There should also be helpful error messages raised if you try to run an integration and are missing any required python packages.
|
||||
|
||||
## Environment Variables
|
||||
The environment variable needed varies based on the integration. See the list of integrations for details.
|
||||
There should also be helpful error messages raised if you try to run an integration and are missing any required environment variables.
|
||||
|
||||
You can set the environment variable in a few ways.
|
||||
If you are trying to set the environment variable `FOO` to value `bar`, here are the ways you could do so:
|
||||
- From the command line:
|
||||
```
|
||||
export FOO=bar
|
||||
```
|
||||
- From the python notebook/script:
|
||||
```python
|
||||
import os
|
||||
os.environ["FOO"] = "bar"
|
||||
```
|
||||
|
||||
For the Getting Started example, we will be using OpenAI's APIs, so we will first need to install their SDK:
|
||||
|
||||
```
|
||||
pip install openai
|
||||
```
|
||||
|
||||
We will then need to set the environment variable. Let's do this from inside the Jupyter notebook (or Python script).
|
||||
|
||||
```python
|
||||
import os
|
||||
os.environ["OPENAI_API_KEY"] = "..."
|

# Quickstart Guide
|
||||
|
||||
|
||||
This tutorial gives you a quick walkthrough about building an end-to-end language model application with LangChain.
|
||||
|
||||
## Installation
|
||||
|
||||
To get started, install LangChain with the following command:
|
||||
|
||||
```bash
|
||||
pip install langchain
|
||||
```
|
||||
|
||||
|
||||
## Environment Setup
|
||||
|
||||
Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
|
||||
|
||||
For this example, we will be using OpenAI's APIs, so we will first need to install their SDK:
|
||||
|
||||
```bash
|
||||
pip install openai
|
||||
```
|
||||
|
||||
We will then need to set the environment variable in the terminal.
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY="..."
|
||||
```
|
||||
|
||||
Alternatively, you could do this from inside the Jupyter notebook (or Python script):
|
||||
|
||||
```python
|
||||
import os
|
||||
os.environ["OPENAI_API_KEY"] = "..."
|
||||
```
|
||||
|
||||
|
||||
## Building a Language Model Application
|
||||
|
||||
Now that we have installed LangChain and set up our environment, we can start building our language model application.
|
||||
|
||||
LangChain provides many modules that can be used to build language model applications. Modules can be combined to create more complex applications, or be used individually for simple applications.
|
||||
|
||||
|
||||
|
||||
`````{dropdown} LLMs: Get predictions from a language model
|
||||
|
||||
The most basic building block of LangChain is calling an LLM on some input.
|
||||
Let's walk through a simple example of how to do this.
|
||||
For this purpose, let's pretend we are building a service that generates a company name based on what the company makes.
|
||||
|
||||
In order to do this, we first need to import the LLM wrapper.
|
||||
|
||||
```python
|
||||
from langchain.llms import OpenAI
|
||||
```
|
||||
|
||||
We can then initialize the wrapper with any arguments.
|
||||
In this example, we probably want the outputs to be MORE random, so we'll initialize it with a HIGH temperature.
|
||||
|
||||
```python
|
||||
llm = OpenAI(temperature=0.9)
|
||||
```
|
||||
|
||||
We can now call it on some input!
|
||||
|
||||
```python
|
||||
text = "What would be a good company name a company that makes colorful socks?"
|
||||
print(llm(text))
|
||||
```
|
||||
|
||||
```pycon
|
||||
Feetful of Fun
|
||||
```
|
||||
|
||||
For more details on how to use LLMs within LangChain, see the [LLM getting started guide](../modules/llms/getting_started.ipynb).
|
||||
`````
|
||||
|
||||
|
||||
`````{dropdown} Prompt Templates: Manage prompts for LLMs
|
||||
|
||||
Calling an LLM is a great first step, but it's just the beginning.
|
||||
Normally when you use an LLM in an application, you are not sending user input directly to the LLM.
|
||||
Instead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.
|
||||
|
||||
For example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.
|
||||
In this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.
|
||||
|
||||
This is easy to do with LangChain!
|
||||
|
||||
First lets define the prompt template:
|
||||
|
||||
```python
|
||||
from langchain.prompts import PromptTemplate
|
||||
|
||||
prompt = PromptTemplate(
|
||||
input_variables=["product"],
|
||||
template="What is a good name for a company that makes {product}?",
|
||||
)
|
||||
```
|
||||
|
||||
Let's now see how this works! We can call the `.format` method to format it.
|
||||
|
||||
```python
|
||||
print(prompt.format(product="colorful socks"))
|
||||
```
|
||||
|
||||
```pycon
|
||||
What is a good name for a company that makes colorful socks?
|
||||
```
|
||||
|
||||
|
||||
[For more details, check out the getting started guide for prompts.](../modules/prompts/getting_started.ipynb)
|
||||
|
||||
`````
|
||||
|
||||
|
||||
|
||||
`````{dropdown} Chains: Combine LLMs and prompts in multi-step workflows
|
||||
|
||||
Up until now, we've worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.
|
||||
|
||||
A chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.
|
||||
|
||||
The most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.
|
||||
|
||||
Extending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.
|
||||
|
||||
```python
|
||||
from langchain.prompts import PromptTemplate
|
||||
from langchain.llms import OpenAI
|
||||
|
||||
llm = OpenAI(temperature=0.9)
|
||||
prompt = PromptTemplate(
|
||||
input_variables=["product"],
|
||||
template="What is a good name for a company that makes {product}?",
|
||||
)
|
||||
```
|
||||
|
||||
We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:
|
||||
|
||||
```python
|
||||
from langchain.chains import LLMChain
|
||||
chain = LLMChain(llm=llm, prompt=prompt)
|
||||
```
|
||||
|
||||
Now we can run that chain only specifying the product!
|
||||
|
||||
```python
|
||||
chain.run("colorful socks")
|
||||
# -> '\n\nSocktastic!'
|
||||
```
|
||||
|
||||
There we go! There's the first chain - an LLM Chain.
|
||||
This is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.
|
||||
|
||||
[For more details, check out the getting started guide for chains.](../modules/chains/getting_started.ipynb)
|
||||
|
||||
`````
|
||||
|
||||
|
||||
`````{dropdown} Agents: Dynamically call chains based on user input
|
||||
|
||||
So far the chains we've looked at run in a predetermined order.
|
||||
|
||||
Agents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.
|
||||
|
||||
When used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.
|
||||
|
||||
|
||||
In order to load agents, you should understand the following concepts:
|
||||
|
||||
- Tool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.
|
||||
- LLM: The language model powering the agent.
|
||||
- Agent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).
|
||||
|
||||
**Agents**: For a list of supported agents and their specifications, see [here](../modules/agents/agents.md).
|
||||
|
||||
**Tools**: For a list of predefined tools and their specifications, see [here](../modules/agents/tools.md).
|
||||
|
||||
For this example, you will also need to install the SerpAPI Python package.
|
||||
|
||||
```bash
|
||||
pip install google-search-results
|
||||
```
|
||||
|
||||
And set the appropriate environment variables.
|
||||
|
||||
```python
|
||||
import os
|
||||
os.environ["SERPAPI_API_KEY"] = "..."
|
||||
```
|
||||
|
||||
Now we can get started!
|
||||
|
||||
```python
|
||||
from langchain.agents import load_tools
|
||||
from langchain.agents import initialize_agent
|
||||
from langchain.llms import OpenAI
|
||||
|
||||
# First, let's load the language model we're going to use to control the agent.
|
||||
llm = OpenAI(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.
|
||||
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, llm, agent="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...
|
||||
I need to find out who Olivia Wilde's boyfriend is and then calculate his age raised to the 0.23 power.
|
||||
Action: Search
|
||||
Action Input: "Olivia Wilde boyfriend"
|
||||
Observation: Jason Sudeikis
|
||||

`````{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/).
|
||||
|
||||
LangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the `ConversationChain`) with two different types of memory.
|
||||
|
||||
By default, the `ConversationChain` has a simple type of memory that remembers all previous inputs/outputs and adds them to the context that is passed. Let's take a look at using this chain (setting `verbose=True` so we can see the prompt).
|
||||
|
||||
```python
|
||||
from langchain import OpenAI, ConversationChain
|
||||
|
||||
llm = OpenAI(temperature=0)
|
||||
conversation = ConversationChain(llm=llm, verbose=True)
|
||||
|
||||
conversation.predict(input="Hi there!")
|
||||
```
|
||||
|
||||
```pycon
|
||||
> Entering new chain...
|
||||
Prompt after formatting:
|
||||
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.
