Fix issue#1712: Update BaseQAWithSourcesChain to handle space & newline after SOURCES: (#2118)
Fix the issue outlined in #1712 to ensure the `BaseQAWithSourcesChain`
can properly separate the sources from an agent response even when they
are delineated by a newline.

This will ensure the `BaseQAWithSourcesChain` can reliably handle both
of these agent outputs:

* `"This Agreement is governed by English law.\nSOURCES: 28-pl"` ->
`"This Agreement is governed by English law.\n`, `"28-pl"`
* `"This Agreement is governed by English law.\nSOURCES:\n28-pl"` ->
`"This Agreement is governed by English law.\n`, `"28-pl"`

I couldn't find any unit tests for this but please let me know if you'd
like me to add any test coverage.

Improve ConversationKGMemory and its function load_memory_variables (#1999)
1. Removed the `summaries` dictionary in favor of directly appending to
the summary_strings list, which avoids the unnecessary double-loop.
2. Simplified the logic for populating the `context` variable.

add token reduction to ConversationalRetrievalChain (#2075)
This worked for me, but I'm not sure if its the right way to approach
something like this, so I'm open to suggestions.

Adds class properties `reduce_k_below_max_tokens: bool` and
`max_tokens_limit: int` to the `ConversationalRetrievalChain`. The code
is basically copied from
[`RetreivalQAWithSourcesChain`](46d141c6cb/langchain/chains/qa_with_sources/retrieval.py (L24))

fix(llms): update default AI21 model to j2, as j1 being deprecated (#2108)
the j1-* models are marked as [Legacy] in the docs and are expected to
be deprecated in 2023-06-01 according to
https://docs.ai21.com/docs/jurassic-1-models-legacy

ensured `tests/integration_tests/llms/test_ai21.py` pass.

empirically observed that `j2-jumbo-instruct` works better the
`j2-jumbo` in various simple agent chains, as also expected given the
prompt templates are mostly zero shot.

include the tool name for on_tool_end callback (#2000)
This is useful if you rely on the `on_tool_end` callback to detect which
tool has finished in a multi agents scenario.

For example, I'm working on a project where I consume the `on_tool_end`
event where the event could be emitted by many agents or tools. Right
now the only way to know which tool has finished would be set a marker
on the `on_tool_start` and catch it on `on_tool_end`.

I didn't want to break the signature of the function, but what would
have been cleaner would be to pass the same details as in
`on_tool_start`

fix: numerous broken documentation links (#2070)
seems linkchecker isn't catching them because it runs on generated html.
at that point the links are already missing.
the generation process seems to strip invalid references when they can't
be re-written from md to html.

I used https://github.com/tcort/markdown-link-check to check the doc
source directly.

There are a few false positives on localhost for development.

Improve chat tool prompt (#1989)
I have found that when the user has not asked an explicit question the
agent might have trouble answering the latest comment and might instead
try to answer a question that came before in the conversation which
would not be what is desired.

I also found that the agent might get confused with the current prompt
and talk about the tools themselves instead of the results obtained from
them.

I added two changes to the tool prompt so that the agent answers only
the last comment/question and only returns information from tool
results.

UnstructuredURLLoader: allow url failures, keep processing (#1954)
By default, UnstructuredURLLoader now continues processing remaining
`urls` if encountering an error for a particular url.

If failure of the entire loader is desired as was previously the case,
use `continue_on_failure=False`.

E.g., this fails splendidly, courtesy of the 2nd url:

```
from langchain.document_loaders import UnstructuredURLLoader
urls = [
    "https://www.understandingwar.org/backgrounder/russian-offensive-campaign-assessment-february-8-2023",
    "https://doesnotexistithinkprobablynotverynotlikely.io",
    "https://www.understandingwar.org/backgrounder/russian-offensive-campaign-assessment-february-9-2023",
]
loader = UnstructuredURLLoader(urls=urls, continue_on_failure=False)
data = loader.load()
```

I guess Olivia Wilde's dating life is too tough to keep track of for

so users who are running their agent for the first time are less likely
to be confused by a result that doesn't match that which is on the docs.

fix import error of bs4 (#1952)
Ran into a broken build if bs4 wasn't installed in the project.

Minor tweak to follow the other doc loaders optional package-loading
conventions.

Also updated html docs to include reference to this new html loader.

side note: Should there be 2 different html-to-text document loaders?
This new one only handles local files, while the existing unstructured
html loader handles HTML from local and remote. So it seems like the
improvement was adding the title to the metadata, which is useful but
could also be added to `html.py`

Propagate "filter" arg in Chroma similarity_search (#1869)
Technically a duplicate fix to #1619 but with unit tests and a small
documentation update
- Propagate `filter` arg in Chroma `similarity_search` to delegated call
to `similarity_search_with_score`
- Add `filter` arg to `similarity_search_by_vector`
- Clarify doc strings on FakeEmbeddings

Remove redundant .docx loader (closes #1716) + update how_to_guides.rst (#1891)
In https://github.com/hwchase17/langchain/issues/1716 , it was
identified that there were two .py files performing similar tasks. As a
resolution, one of the files has been removed, as its purpose had
already been fulfilled by the other file. Additionally, the init has
been updated accordingly.

Furthermore, the how_to_guides.rst file has been updated to include
links to documentation that was previously missing. This was deemed
necessary as the existing list on
https://langchain.readthedocs.io/en/latest/modules/document_loaders/how_to_guides.html
was incomplete, causing confusion for users who rely on the full list of
documentation on the left sidebar of the website.

Fix minor bug in opensearch vector store add_texts function (#1878)
In the langchain.vectorstores.opensearch_vector_search.py, in the
add_texts function, around line 247, we have the following code

```python
embeddings = [
     self.embedding_function.embed_documents(list(text))[0] for text in texts
]
```

the goal of the `list(text)` part I believe is to pass a list to the
embed_documents list instead of a a str. However, `list(text)` is a
subtle bug

`list(text)` would convert the string text into an array, where each
element of the array is a character of the string

<img width="937" alt="Screenshot 2023-03-22 at 1 27 18 PM"
src="https://user-images.githubusercontent.com/88190553/226836470-384665a1-2f13-46bc-acfc-9a37417cd918.png">

The correct way should be to change the code to 

```python
embeddings = [
      self.embedding_function.embed_documents([text])[0] for text in texts
]
```
Which wraps the string inside a list.

docs: update gpt index references to LlamaIndex (#1856)
The GPT Index project is transitioning to the new project name,
LlamaIndex.

I've updated a few files referencing the old project name and repository
URL to the current ones.

From the [LlamaIndex repo](https://github.com/jerryjliu/llama_index):
> NOTE: We are rebranding GPT Index as LlamaIndex! We will carry out
this transition gradually.
>
> 2/25/2023: By default, our docs/notebooks/instructions now reference
"LlamaIndex" instead of "GPT Index".
>
> 2/19/2023: By default, our docs/notebooks/instructions now use the
llama-index package. However the gpt-index package still exists as a
duplicate!
>
> 2/16/2023: We have a duplicate llama-index pip package. Simply replace
all imports of gpt_index with llama_index if you choose to pip install
llama-index.

I'm not associated with LlamaIndex in any way. I just noticed the
discrepancy when studying the lanchain documentation.

[Embeddings] Add SageMaker Endpoint Embedding class (#1859)
# What does this PR do? 

This PR adds similar to `llms` a SageMaker-powered `embeddings` class.
This is helpful if you want to leverage Hugging Face models on SageMaker
for creating your indexes.

I added a example into the
[docs/modules/indexes/examples/embeddings.ipynb](https://github.com/hwchase17/langchain/compare/master...philschmid:add-sm-embeddings?expand=1#diff-e82629e2894974ec87856aedd769d4bdfe400314b03734f32bee5990bc7e8062)
document. The example currently includes some `_### TEMPORARY: Showing
how to deploy a SageMaker Endpoint from a Hugging Face model ###_ ` code
showing how you can deploy a sentence-transformers to SageMaker and then
run the methods of the embeddings class.

@hwchase17 please let me know if/when i should remove the `_###
TEMPORARY: Showing how to deploy a SageMaker Endpoint from a Hugging
Face model ###_` in the description i linked to a detail blog on how to
deploy a Sentence Transformers so i think we don't need to include those
steps here.

I also reused the `ContentHandlerBase` from
`langchain.llms.sagemaker_endpoint` and changed the output type to `any`
since it is depending on the implementation.

Use the following code to test:

```python
import os
from langchain.llms import OpenAI
from langchain.chains.api import podcast_docs
from langchain.chains import APIChain

# Get api key here: https://openai.com/pricing
os.environ["OPENAI_API_KEY"] = "sk-xxxxx"

# Get api key here: https://www.listennotes.com/api/pricing/
listen_api_key = 'xxx'

llm = OpenAI(temperature=0)
headers = {"X-ListenAPI-Key": listen_api_key}
chain = APIChain.from_llm_and_api_docs(llm, podcast_docs.PODCAST_DOCS, headers=headers, verbose=True)
chain.run("Search for 'silicon valley bank' podcast episodes, audio length is more than 30 minutes, return only 1 results")
```

Known issues: the api response data might be too big, and we'll get such
error:

Use embedding instead of embedding function in ElasticVectorStore (#1692)
While it might be a bit more restrictive, I find that using the
Embedding interface as an input for the vector store creation is better
than an embedding function because we can use bulk requests and possibly
the retry logic if needed.

I have seen that some vector store implementations use Embedding while
others use embedding function so I don't know what is the criteria to
have one or the other, in my opinion they should all just be Embedding
or have a way more complex embedding function that accepts multiple
texts instead of one by one.

Fix Document & Expose StringPromptTemplate as a custom-prompt-template. (#1753)

the document [Creating a custom prompt

To address this, I have made the following changes:

1. Updated the guide in the document to use `StringPromptTemplate`
instead of `BasePromptTemplate`.
2. Exposed `StringPromptTemplate` in `prompts/__init__.py` for easier
importing.

fix: agent json parser fails with text in suffix (#1734)
While testing out `VectorDBQA` as a `Tool` for one of the conversation,
I happened to get a response from LLM (OpenAI) like this

<code>
Could not parse LLM output: Here's a response using the Product Search
tool:

```json
{
    "action": "Product Search",
    "action_input": "pots for plants"
}
```

This will allow you to search for pots for your plants and find a
variety of options that are available for purchase. You can use this
information to choose the pots that best fit your needs and preferences.
</code>

i.e. The response had a text before & *after* the expected JSON, leading
to `JSONDecodeError`. It's fixed now, by removing text after '```' to
remove unwanted text.

The error I encountered in this Jupyter Notebook -

class Joke(BaseModel):

joke_query = "Tell me a joke."

# Or, an example with compound type fields.
#class FloatArray(BaseModel):
#    values: List[float] = Field(description="list of floats")
#
#float_array_query = "Write out a few terms of fiboacci."

model = OpenAI(model_name='text-davinci-003', temperature=0.0)

prompt = PromptTemplate(
    template="Answer the user query.\n{format_instructions}\n{query}\n",

output = model(_input.to_string())
print("Completion:\n", output)
parsed_output = parser.parse(output)
print("Parsed completion:\n", parsed_output)
```

```
Prompt:
 Answer the user query.
The output should be formatted as a JSON instance that conforms to the JSON schema below.  For example, the object {"foo":  ["bar", "baz"]} conforms to the schema {"foo": {"description": "a list of strings field", "type": "string"}}.

Here is the output schema:
---
{"setup": {"description": "question to set up a joke", "type": "string"}, "punchline": {"description": "answer to resolve the joke", "type": "string"}}
---

Tell me a joke.

Completion:
 {"setup": "Why don't scientists trust atoms?", "punchline": "Because they make up everything!"}

Parsed completion:
 setup="Why don't scientists trust atoms?" punchline='Because they make up everything!'
```

Ofc, works only with LMs of sufficient capacity. DaVinci is reliable but
not always.

fallback to {} for None metadata from Chroma (#1714)

feat: allow the unstructured kwargs to be passed in to Unstructured document loaders (#1667)
### Summary

Allows users to pass in `**unstructured_kwargs` to Unstructured document
loaders. Implemented with the `strategy` kwargs in mind, but will pass
in other kwargs like `include_page_breaks` as well. The two currently
supported strategies are `"hi_res"`, which is more accurate but takes
longer, and `"fast"`, which processes faster but with lower accuracy.
The `"hi_res"` strategy is the default. For PDFs, if `detectron2` is not
available and the user selects `"hi_res"`, the loader will fallback to
using the `"fast"` strategy.


### Testing

#### Make sure the `strategy` kwarg works

Run the following in iPython to verify that the `"fast"` strategy is
indeed faster.

```python
from langchain.document_loaders import UnstructuredFileLoader

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")
%timeit loader.load()

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")
%timeit loader.load()
```

On my system I get:

```python
In [3]: from langchain.document_loaders import UnstructuredFileLoader

In [4]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")

In [5]: %timeit loader.load()
247 ms ± 369 µs per loop (mean ± std. dev. of 7 runs, 1 loop each)

In [6]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")

In [7]: %timeit loader.load()
2.45 s ± 31 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
```

#### Make sure older versions of `unstructured` still work

Run `pip install unstructured==0.5.3` and then verify the following runs
without error:

```python
from langchain.document_loaders import UnstructuredFileLoader

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf",  mode="elements")
loader.load()
```

sql: do not hard code the LIMIT clause in the table_info section (#1563)
Seeing a lot of issues in Discord in which the LLM is not using the
correct LIMIT clause for different SQL dialects. ie, it's using `LIMIT`
for mssql instead of `TOP`, or instead of `ROWNUM` for Oracle, etc.
I think this could be due to us specifying the LIMIT statement in the
example rows portion of `table_info`. So the LLM is seeing the `LIMIT`
statement used in the prompt.
Since we can't specify each dialect's method here, I think it's fine to
just replace the `SELECT... LIMIT 3;` statement with `3 rows from
table_name table:`, and wrap everything in a block comment directly
following the `CREATE` statement. The Rajkumar et al paper wrapped the
example rows and `SELECT` statement in a block comment as well anyway.
Thoughts @fpingham?

cleanup: unify 3 different pdf loaders, rename PagedPDFSplitter (#1615)
`OnlinePDFLoader` and `PagedPDFSplitter` lived separate from the rest of
the pdf loaders.

Because they're all similar, I propose moving all to `pdy.py` and the
same docs/examples page.

Additionally, `PagedPDFSplitter` naming doesn't match the pattern the
rest of the loaders follow, so I renamed to `PyPDFLoader` and had it
inherit from `BasePDFLoader` so it can now load from remote file
sources.

Add regex dict: (#1616)
This class enables us to send a dictionary containing an output key and
the expected format, which in turn allows us to retrieve the result of
the matching formats and extract specific information from it.

To exclude irrelevant information from our return dictionary, we can
prompt the LLM to use a specific command that notifies us when it
doesn't know the answer. We refer to this variable as the
"no_update_value".

Regarding the updated regular expression pattern
(r"{}:\s?([^.'\n']*).?"), it enables us to retrieve a format as 'Output
Key':'value'.

We have improved the regex by adding an optional space between ':' and
'value' with "s?", and by excluding points and line jumps from the
matches using "[^.'\n']*".

Add read only shared memory (#1491)
Provide shared memory capability for the Agent.
Inspired by #1293 .

## Problem

If both Agent and Tools (i.e., LLMChain) use the same memory, both of
them will save the context. It can be annoying in some cases.


## Solution

Create a memory wrapper that ignores the save and clear, thereby
preventing updates from Agent or Tools.

[bugfix] Fix persisted chromadb vectorstore (#1444)
If a `persist_directory` param was set, chromadb would throw a warning
that ""No embedding_function provided, using default embedding function:
SentenceTransformerEmbeddingFunction". and would error with a `Illegal
instruction: 4` error.

This is on a MBP M1 13.2.1, python 3.9.

I'm not entirely sure why that error happened, but when using
`get_or_create_collection` instead of `list_collection` on our end, the
error and warning goes away and chroma works as expected.

Added bonus this is cleaner and likely more efficient.
`list_collections` builds a new `Collection` instance for each collect,
then `Chroma` would just use the `name` field to tell if the collection
existed.

Add optional base_url arg to GitbookLoader (#1552)
First of all, big kudos on what you guys are doing, langchain is
enabling some really amazing usecases and I'm having lot's of fun
playing around with it. It's really cool how many data sources it
supports out of the box.

However, I noticed some limitations of the current `GitbookLoader` which
this PR adresses:

The main change is that I added an optional `base_url` arg to
`GitbookLoader`. This enables use cases where one wants to crawl docs
from a start page other than the index page, e.g., the following call
would scrape all pages that are reachable via nav bar links from
"https://docs.zenml.io/v/0.35.0":

```python
GitbookLoader(
    web_page="https://docs.zenml.io/v/0.35.0", 
    load_all_paths=True,
    base_url="https://docs.zenml.io",
)
```

Previously, this would fail because relative links would be of the form
`/v/0.35.0/...` and the full link URLs would become
`docs.zenml.io/v/0.35.0/v/0.35.0/...`.

I also fixed another issue of the `GitbookLoader` where the link URLs
were constructed incorrectly as `website//relative_url` if the provided
`web_page` had a trailing slash.

Added other evaluation metrics for data-augmented QA (#1521)
This PR adds additional evaluation metrics for data-augmented QA,
resulting in a report like this at the end of the notebook:

![Screen Shot 2023-03-08 at 8 53 23
AM](https://user-images.githubusercontent.com/398875/223731199-8eb8e77f-5ff3-40a2-a23e-f3bede623344.png)

The score calculation is based on the
[Critique](https://docs.inspiredco.ai/critique/) toolkit, an API-based
toolkit (like OpenAI) that has minimal dependencies, so it should be
easy for people to run if they choose.

The code could further be simplified by actually adding a chain that
calls Critique directly, but that probably should be saved for another
PR if necessary. Any comments or change requests are welcome!

from langchain.vectorstores import Chroma

chroma_settings = Settings(chroma_api_impl="rest",

Support S3 Object keys with / in S3FileLoader (#1517)
Resolves https://github.com/hwchase17/langchain/issues/1510

### Problem
When loading S3 Objects with `/` in the object key (eg.
`folder/some-document.txt`) using `S3FileLoader`, the objects are
downloaded into a temporary directory and saved as a file.

This errors out when the parent directory does not exist within the
temporary directory.

See
https://github.com/hwchase17/langchain/issues/1510#issuecomment-1459583696
on how to reproduce this bug

### What this pr does
Creates parent directories based on object key. 

This also works with deeply nested keys:
`folder/subfolder/some-document.txt`

Change method to calculate number of tokens for OpenAIChat (#1457)
Solves https://github.com/hwchase17/langchain/issues/1412

Currently `OpenAIChat` inherits the way it calculates the number of
tokens, `get_num_token`, from `BaseLLM`.
In the other hand `OpenAI` inherits from `BaseOpenAI`. 

`BaseOpenAI` and `BaseLLM` uses different methodologies for doing this.
The first relies on `tiktoken` while the second on `GPT2TokenizerFast`.

The motivation of this PR is:

1. Bring consistency about the way of calculating number of tokens
`get_num_token` to the `OpenAI` family, regardless of `Chat` vs `non
Chat` scenarios.
2. Give preference to the `tiktoken` method as it's serverless friendly.
It doesn't require downloading models which might make it incompatible
with `readonly` filesystems.

Fix type hint of 'vectorstore_cls' arg in SemanticSimilarityExampleSelector (#1427)
Hello! Thank you for the amazing library you've created!

While following the tutorial at [the link(`Using an example
selector`)](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/few_shot_examples.html#using-an-example-selector),
I noticed that passing Chroma as an argument to from_examples results in
a type hint error.

Error message(mypy):
```
Argument 3 to "from_examples" of "SemanticSimilarityExampleSelector" has incompatible type "Type[Chroma]"; expected "VectorStore"  [arg-type]mypy(error)
```

This pull request fixes the type hint and allows the VectorStore class
to be specified as an argument.

`LIKE 'asdf%'` will result in a value error with mysql, mariadb, and
maybe some others. This is one way to fix it - the alternative is to
simply double up %, like `LIKE 'asdf%%'` but this seemed cleaner in
terms of output.
Fixes #1383

Minor documentation update in initialize_agent (#1397)
Updating documentation in initialize_agent.

One thing that could benefit from further clarification is the
responsibility
breakdown by between an AgentExecutor vs. an Agent. The documentation
for an
AgentExecutor does not clarify that. From the class attributes, it
appears that
executor has access to the tools, while the agent is only aware of the
tool
names. Anyway, additional clarification would be beneficial on the
AgentExecutor class.

Return Cohere embeddings as lists of floats (#1394)
This PR fixes the types returned by Cohere embeddings. Currently, Cohere
client returns instances of `cohere.embeddings.Embeddings`. Since the
transport layer relies on JSON, some numbers might be represented as
ints, not floats, which happens quite often. While that doesn't seem to
be an issue, it breaks some pydantic models if they require strict
floats.

Update examples to prevent confusing missing _type warning (#1391)
The YAML and JSON examples of prompt serialization now give a strange
`No '_type' key found, defaulting to 'prompt'` message when you try to
run them yourself or copy the format of the files. The reason for this
harmless warning is that the _type key was not in the config files,
which means they are parsed as a standard prompt.

This could be confusing to new users (like it was confusing to me after
upgrading from 0.0.85 to 0.0.86+ for my few_shot prompts that needed a
_type added to the example_prompt config), so this update includes the
_type key just for clarity.

Obviously this is not critical as the warning is harmless, but it could
be confusing to track down or be interpreted as an error by a new user,
so this update should resolve that.

add option to use user-defined SQL table info (#1347)
Currently, table information is gathered through SQLAlchemy as complete
table DDL and a user-selected number of sample rows from each table.
This PR adds the option to use user-defined table information instead of
automatically collecting it. This will use the provided table
information and fall back to the automatic gathering for tables that the
user didn't provide information for.

Off the top of my head, there are a few cases where this can be quite
useful:
- The first n rows of a table are uninformative, or very similar to one
another. In this case, hand-crafting example rows for a table such that
they provide the good, diverse information can be very helpful. Another
approach we can think about later is getting a random sample of n rows
instead of the first n rows, but there are some performance
considerations that need to be taken there. Even so, hand-crafting the
sample rows is useful and can guarantee the model sees informative data.
- The user doesn't want every column to be available to the model. This
is not an elegant way to fulfill this specific need since the user would
have to provide the table definition instead of a simple list of columns
to include or ignore, but it does work for this purpose.
- For the developers, this makes it a lot easier to compare/benchmark
the performance of different prompting structures for providing table
information in the prompt.

These are cases I've run into myself (particularly cases 1 and 3) and
I've found these changes useful. Personally, I keep custom table info
for a few tables in a yaml file for versioning and easy loading.

Definitely open to other opinions/approaches though!

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

noise, what's wrong with it?" can yield significantly better responses
than context free response from LLMs.

This page covers how to use the Postgres [PGVector](https://github.com/pgvector/pgvector) ecosystem within LangChain
It is broken into two parts: installation and setup, and then references to specific PGVector wrappers.
## Installation
- Install the Python package with `pip install pgvector`
## Setup
1. The first step is to create a database with the `pgvector` extension installed.
Follow the steps at [PGVector Installation Steps](https://github.com/pgvector/pgvector#installation) to install the database and the extension. The docker image is the easiest way to get started.
## Wrappers
### VectorStore
There exists a wrapper around Postgres vector databases, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
```python
from langchain.vectorstores.pgvector import PGVector
```
### Usage
For a more detailed walkthrough of the PGVector Wrapper, see [this notebook](../modules/indexes/vectorstores/examples/pgvector.ipynb)

llm = PromptLayerOpenAI(pl_tags=["langchain-requests", "chatbot"]) llm = PromptLayerOpenAI(pl_tags=["langchain-requests", "chatbot"])
``` ```
This LLM is identical to the [OpenAI LLM](./openai), except that To get the PromptLayer request id, use the argument `return_pl_id` when instanializing the LLM
```python
from langchain.llms import PromptLayerOpenAI
llm = PromptLayerOpenAI(return_pl_id=True)
```
This will add the PromptLayer request ID in the `generation_info` field of the `Generation` returned when using `.generate` or `.agenerate`
For example:
```python
llm_results = llm.generate(["hello world"])
for res in llm_results.generations:
print("pl request id: ", res[0].generation_info["pl_request_id"])
```
You can use the PromptLayer request ID to add a prompt, score, or other metadata to your request. [Read more about it here](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9).
This LLM is identical to the [OpenAI LLM](./openai.md), except that
- all your requests will be logged to your PromptLayer account - all your requests will be logged to your PromptLayer account
- you can add `pl_tags` when instantializing to tag your requests on PromptLayer - you can add `pl_tags` when instantializing to tag your requests on PromptLayer
- you can add `return_pl_id` when instantializing to return a PromptLayer request id to use [while tracking requests](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9).
PromptLayer also provides native wrappers for [`PromptLayerChatOpenAI`](../modules/models/chat/integrations/promptlayer_chatopenai.ipynb) and `PromptLayerOpenAIChat`

# 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 [flan-t5 model](https://replicate.com/daanelson/flan-t5), click on the API tab. The model name/version would be: `daanelson/flan-t5:04e422a9b85baed86a4f24981d7f9953e20c5fd82f6103b74ebc431588e1cec8`
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="daanelson/flan-t5:04e422a9b85baed86a4f24981d7f9953e20c5fd82f6103b74ebc431588e1cec8")
```
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")
```

- 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. instances](https://searx.space/) these instances frequently do not permit API
- To run a self-hosted instance see [this page](https://searxng.github.io/searxng/admin/installation.html) for more information. access (see note on output format below) and have limitations on the frequency
- To use the tool you need to provide the searx host url by: of requests. It is recommended to opt for a self-hosted instance instead.
1. passing the named parameter `searx_host` when creating the instance.
2. exporting the environment variable `SEARXNG_HOST`. ### 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.

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/). So far, all the chains and agents we've gone through have been stateless.

## 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.
`````{dropdown} 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="Translate this sentence from English to French. 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="Translate this sentence from English to French. I love programming.")
],
[
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="Translate this sentence from English to French. 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': 71, 'completion_tokens': 18, 'total_tokens': 89}})
```
You can recover things like token usage from this LLMResult:
```
result.llm_output['token_usage']
# -> {'prompt_tokens': 71, 'completion_tokens': 18, 'total_tokens': 89}
```
`````
`````{dropdown} 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 convience, 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={})
```
`````
`````{dropdown} 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."
```
`````
`````{dropdown} Agents with Chat Models
Agents can also be used with chat models, you can initialize one using `"chat-zero-shot-react-description"` as the agent type.
```python
from langchain.agents import load_tools
from langchain.agents import initialize_agent
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="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.

> Finished chain.
'2.169459462491557'
```
`````
`````{dropdown} 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 Welcome to LangChain
========================== ==========================
Large language models (LLMs) are emerging as a transformative technology, enabling 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 via an API, but will also:
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.
This library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include: - *Be data-aware*: connect a language model to other sources of data
- *Be agentic*: allow a language model to interact with its environment
**❓ Question Answering over specific documents** The LangChain framework is designed with the above principles in mind.
- `Documentation <./use_cases/question_answering.html>`_ 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/>`_.

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.
- `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. - `Personal Assistants <./use_cases/personal_assistants.html>`_: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.
- `Question Answering <./use_cases/question_answering.html>`_: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.

Agents use an LLM to determine which actions to take and in what order. Agents 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. An action can either be using a tool and observing its output, or returning a response to the user.
For a list of easily loadable tools, see [here](tools.md).

"# Serialization\n",
"\n",
"This notebook goes over how to serialize agents. For this notebook, it is important to understand the distinction we draw between `agents` and `tools`. An agent is the LLM powered decision maker that decides which actions to take and in which order. Tools are various instruments (functions) an agent has access to, through which an agent can interact with the outside world. When people generally use agents, they primarily talk about using an agent WITH tools. However, when we talk about serialization of agents, we are talking about the agent by itself. We plan to add support for serializing an agent WITH tools sometime in the future.\n",

# Key Concepts
## Agents
Agents use an LLM to determine which actions to take and in what order.
For more detailed information on agents, and different types of agents in LangChain, see [this documentation](agents.md).
## Tools
Tools are functions that agents can use to interact with the world.
These tools can be generic utilities (e.g. search), other chains, or even other agents.
For more detailed information on tools, and different types of tools in LangChain, see [this documentation](tools.md).

Tools
=============
.. note::
`Conceptual Guide <https://docs.langchain.com/docs/components/agents/tool>`_
Tools are ways that an agent can use to interact with the outside world.
For an overview of what a tool is, how to use them, and a full list of examples, please see the getting started documentation
.. toctree::
:maxdepth: 1
:glob:
./tools/getting_started.md
Next, we have some examples of customizing and generically working with tools
.. toctree::
:maxdepth: 1
:glob:
./tools/custom_tools.ipynb
./tools/multi_input_tool.ipynb
In this documentation we cover generic tooling functionality (eg how to create your own)
as well as examples of tools and how to use them.
.. toctree::
:maxdepth: 1

"# Zapier Natural Language Actions API\n",
"\\\n",
"Full docs here: https://nla.zapier.com/api/v1/docs\n",
"\n",
"**Zapier Natural Language Actions** gives you access to the 5k+ apps, 20k+ actions on Zapier's platform through a natural language API interface.\n",
"\n",
"NLA supports apps like Gmail, Salesforce, Trello, Slack, Asana, HubSpot, Google Sheets, Microsoft Teams, and thousands more apps: https://zapier.com/apps\n",
"\n",
"Zapier NLA handles ALL the underlying API auth and translation from natural language --> underlying API call --> return simplified output for LLMs. The key idea is you, or your users, expose a set of actions via an oauth-like setup window, which you can then query and execute via a REST API.\n",
"\n",
"NLA offers both API Key and OAuth for signing NLA API requests.\n",
"\n",
"1. Server-side (API Key): for quickly getting started, testing, and production scenarios where LangChain will only use actions exposed in the developer's Zapier account (and will use the developer's connected accounts on Zapier.com)\n",
"\n",
"2. User-facing (Oauth): for production scenarios where you are deploying an end-user facing application and LangChain needs access to end-user's exposed actions and connected accounts on Zapier.com\n",
"\n",
"This quick start will focus on the server-side use case for brevity. Review [full docs](https://nla.zapier.com/api/v1/docs) or reach out to nla@zapier.com for user-facing oauth developer support.\n",
"\n",
"This example goes over how to use the Zapier integration with a `SimpleSequentialChain`, then an `Agent`.\n",

Generic Chains
--------------
A chain is made up of links, which can be either primitives or other chains.
Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains.
The examples here are all generic end-to-end chains that are meant to be used to construct other chains rather than serving a specific purpose.
**LLMChain**
- **Links Used**: PromptTemplate, LLM
- **Notes**: This chain is the simplest chain, and is widely used by almost every other chain. This chain takes arbitrary user input, creates a prompt with it from the PromptTemplate, passes that to the LLM, and then returns the output of the LLM as the final output.
- `Example Notebook <./generic/llm_chain.html>`_
**Transformation Chain**
- **Links Used**: TransformationChain
- **Notes**: This notebook shows how to use the Transformation Chain, which takes an arbitrary python function and applies it to inputs/outputs of other chains.
- `Example Notebook <./generic/transformation.html>`_
**Sequential Chain**
- **Links Used**: Sequential
- **Notes**: This notebook shows how to combine calling multiple other chains in sequence.
- `Example Notebook <./generic/sequential_chains.html>`_

Primitives can be either `prompts <../prompts.html>`_, `llms <../llms.html>`_, `utils <../utils.html>`_, or other chains. Primitives can be either `prompts <../prompts.html>`_, `models <../models.html>`_, arbitrary functions, or other chains.
The examples here are all end-to-end chains for specific applications. The examples here are broken up into three sections:
They are broken up into three categories:
1. `Generic Chains <./generic_how_to.html>`_: Generic chains, that are meant to help build other chains rather than serve a particular purpose. **Generic Functionality**
2. `Utility Chains <./utility_how_to.html>`_: Chains consisting of an LLMChain interacting with a specific util.
3. `Asynchronous <./async_chain.html>`_: Covering asynchronous functionality. Covers both generic chains (that are useful in a wide variety of applications) as well as generic functionality related to those chains.
