SQLDatabase: adding security disclamer (#7710)
It might be obvious to most engineers, but I think everybody should be
cautious when using such a chain.

Simplify GraphQL Tool Initialization documentation by Removing 'llm' Argument (#7651)
This PR is aimed at enhancing the clarity of the documentation in the
langchain project.

**Description**:
In the graphql.ipynb file, I have removed the unnecessary 'llm' argument
from the initialization process of the GraphQL tool (of type
_EXTRA_OPTIONAL_TOOLS). The 'llm' argument is not required for this
process. Its presence could potentially confuse users. This modification
simplifies the understanding of tool initialization and minimizes
potential confusion.

**Issue**: Not applicable, as this is a documentation improvement.

**Dependencies**: None.

**I kindly request a review from the following maintainer**: @hinthornw,
who is responsible for Agents / Tools / Toolkits.

No new integration is being added in this PR, hence no need for a test
or an example notebook.

Please see the changes for more detail and let me know if any further
modification is necessary.

WhyLabsCallbackHandler updates (#7621)
Updates to the WhyLabsCallbackHandler and example notebook
- Update dependency to langkit 0.0.6 which defines new helper methods
for callback integrations
- Update WhyLabsCallbackHandler to use the new `get_callback_instance`
so that the callback is mostly defined in langkit
- Remove much of the implementation of the WhyLabsCallbackHandler here
in favor of the callback instance

This does not change the behavior of the whylabs callback handler
implementation but is a reorganization that moves some of the
implementation externally to our optional dependency package, and should
make future updates easier.

Fix make docs_build and related scripts (#7276)
**Description: a description of the change**

Fixed `make docs_build` and related scripts which caused errors. There
are several changes.

First, I made the build of the documentation and the API Reference into
two separate commands. This is because it takes less time to build. The
commands for documents are `make docs_build`, `make docs_clean`, and
`make docs_linkcheck`. The commands for API Reference are `make
api_docs_build`, `api_docs_clean`, and `api_docs_linkcheck`.

It looked like `docs/.local_build.sh` could be used to build the
documentation, so I used that. Since `.local_build.sh` was also building
API Rerefence internally, I removed that process. `.local_build.sh` also
added some Bash options to stop in error or so. Futher more added `cd
"${SCRIPT_DIR}"` at the beginning so that the script will work no matter
which directory it is executed in.

`docs/api_reference/api_reference.rst` is removed, because which is
generated by `docs/api_reference/create_api_rst.py`, and added it to
.gitignore.

Finally, the description of CONTRIBUTING.md was modified.

**Issue: the issue # it fixes (if applicable)**

https://github.com/hwchase17/langchain/issues/6413

**Dependencies: any dependencies required for this change**

`nbdoc` was missing in group docs so it was added. I installed it with
the `poetry add --group docs nbdoc` command. I am concerned if any
modifications are needed to poetry.lock. I would greatly appreciate it
if you could pay close attention to this file during the review.

CPAL (#6255)
# Causal program-aided language (CPAL) chain

## Motivation

This builds on the recent [PAL](https://arxiv.org/abs/2211.10435) to
stop LLM hallucination. The problem with the
[PAL](https://arxiv.org/abs/2211.10435) approach is that it hallucinates
on a math problem with a nested chain of dependence. The innovation here
is that this new CPAL approach includes causal structure to fix
hallucination.

For example, using the below word problem, PAL answers with 5, and CPAL
answers with 13.

    "Tim buys the same number of pets as Cindy and Boris."
    "Cindy buys the same number of pets as Bill plus Bob."
    "Boris buys the same number of pets as Ben plus Beth."
    "Bill buys the same number of pets as Obama."
    "Bob buys the same number of pets as Obama."
    "Ben buys the same number of pets as Obama."
    "Beth buys the same number of pets as Obama."
    "If Obama buys one pet, how many pets total does everyone buy?"

The CPAL chain represents the causal structure of the above narrative as
a causal graph or DAG, which it can also plot, as shown below.


![complex-graph](https://github.com/hwchase17/langchain/assets/367522/d938db15-f941-493d-8605-536ad530f576)

.

The two major sections below are:

1. Technical overview
2. Future application

Also see [this jupyter
notebook](https://github.com/borisdev/langchain/blob/master/docs/extras/modules/chains/additional/cpal.ipynb)
doc.


## 1. Technical overview

### CPAL versus PAL

Like [PAL](https://arxiv.org/abs/2211.10435), CPAL intends to reduce
large language model (LLM) hallucination.

The CPAL chain is different from the PAL chain for a couple of reasons. 

* CPAL adds a causal structure (or DAG) to link entity actions (or math
expressions).
* The CPAL math expressions are modeling a chain of cause and effect
relations, which can be intervened upon, whereas for the PAL chain math
expressions are projected math identities.

PAL's generated python code is wrong. It hallucinates when complexity
increases.

```python
def solution():
    """Tim buys the same number of pets as Cindy and Boris.Cindy buys the same number of pets as Bill plus Bob.Boris buys the same number of pets as Ben plus Beth.Bill buys the same number of pets as Obama.Bob buys the same number of pets as Obama.Ben buys the same number of pets as Obama.Beth buys the same number of pets as Obama.If Obama buys one pet, how many pets total does everyone buy?"""
    obama_pets = 1
    tim_pets = obama_pets
    cindy_pets = obama_pets + obama_pets
    boris_pets = obama_pets + obama_pets
    total_pets = tim_pets + cindy_pets + boris_pets
    result = total_pets
    return result  # math result is 5
```

CPAL's generated python code is correct.

```python
story outcome data
    name                                   code  value      depends_on
0  obama                                   pass    1.0              []
1   bill               bill.value = obama.value    1.0         [obama]
2    bob                bob.value = obama.value    1.0         [obama]
3    ben                ben.value = obama.value    1.0         [obama]
4   beth               beth.value = obama.value    1.0         [obama]
5  cindy   cindy.value = bill.value + bob.value    2.0     [bill, bob]
6  boris   boris.value = ben.value + beth.value    2.0     [ben, beth]
7    tim  tim.value = cindy.value + boris.value    4.0  [cindy, boris]

query data
{
    "question": "how many pets total does everyone buy?",
    "expression": "SELECT SUM(value) FROM df",
    "llm_error_msg": ""
}
# query result is 13
```

Based on the comments below, CPAL's intended location in the library is
`experimental/chains/cpal` and PAL's location is`chains/pal`.

### CPAL vs Graph QA

Both the CPAL chain and the Graph QA chain extract entity-action-entity
relations into a DAG.

The CPAL chain is different from the Graph QA chain for a few reasons.

* Graph QA does not connect entities to math expressions
* Graph QA does not associate actions in a sequence of dependence.
* Graph QA does not decompose the narrative into these three parts:
  1. Story plot or causal model
  4. Hypothetical question
  5. Hypothetical condition 

### Evaluation

Preliminary evaluation on simple math word problems shows that this CPAL
chain generates less hallucination than the PAL chain on answering
questions about a causal narrative. Two examples are in [this jupyter
notebook](https://github.com/borisdev/langchain/blob/master/docs/extras/modules/chains/additional/cpal.ipynb)
doc.

## 2. Future application

### "Describe as Narrative, Test as Code"

The thesis here is that the Describe as Narrative, Test as Code approach
allows you to represent a causal mental model both as code and as a
narrative, giving you the best of both worlds.

#### Why describe a causal mental mode as a narrative?

The narrative form is quick. At a consensus building meeting, people use
narratives to persuade others of their causal mental model, aka. plan.
You can share, version control and index a narrative.

#### Why test a causal mental model as a code?

Code is testable, complex narratives are not. Though fast, narratives
are problematic as their complexity increases. The problem is LLMs and
humans are prone to hallucination when predicting the outcomes of a
narrative. The cost of building a consensus around the validity of a
narrative outcome grows as its narrative complexity increases. Code does
not require tribal knowledge or social power to validate.

Code is composable, complex narratives are not. The answer of one CPAL
chain can be the hypothetical conditions of another CPAL Chain. For
stochastic simulations, a composable plan can be integrated with the
[DoWhy library](https://github.com/py-why/dowhy). Lastly, for the
futuristic folk, a composable plan as code allows ordinary community
folk to design a plan that can be integrated with a blockchain for
funding.

An explanation of a dependency planning application is

feat: support generate as an early stopping method for OpenAIFunctionsAgent (#7229)
This PR proposes an implementation to support `generate` as an
`early_stopping_method` for the new `OpenAIFunctionsAgent` class.

The motivation behind is to facilitate the user to set a maximum number
of actions the agent can take with `max_iterations` and force a final
response with this new agent (as with the `Agent` class).

The following changes were made:

- The `OpenAIFunctionsAgent.return_stopped_response` method was
overwritten to support `generate` as an `early_stopping_method`
- A boolean `with_functions` parameter was added to the
`OpenAIFunctionsAgent.plan` method

This way the `OpenAIFunctionsAgent.return_stopped_response` method can
call the `OpenAIFunctionsAgent.plan` method with `with_function=False`
when the `early_stopping_method` is set to `generate`, making a call to
the LLM with no functions and forcing a final response from the
`"assistant"`.

Add Xorbits Dataframe as a Document Loader (#7319)
- [Xorbits](https://doc.xorbits.io/en/latest/) is an open-source
computing framework that makes it easy to scale data science and machine
learning workloads in parallel. Xorbits can leverage multi cores or GPUs
to accelerate computation on a single machine, or scale out up to
thousands of machines to support processing terabytes of data.

- This PR added support for the Xorbits document loader, which allows
langchain to leverage Xorbits to parallelize and distribute the loading
of data.
- Dependencies: This change requires the Xorbits library to be installed
in order to be used.
`pip install xorbits`

Add ZepMemory; improve ZepChatMessageHistory handling of metadata; Fix bugs (#7444)
Hey @hwchase17 - 

This PR adds a `ZepMemory` class, improves handling of Zep's message
metadata, and makes it easier for folks building custom chains to
persist metadata alongside their chat history.

We've had plenty confused users unfamiliar with ChatMessageHistory
classes and how to wrap the `ZepChatMessageHistory` in a
`ConversationBufferMemory`. So we've created the `ZepMemory` class as a
light wrapper for `ZepChatMessageHistory`.

Details:
- add ZepMemory, modify notebook to demo use of ZepMemory
- Modify summary to be SystemMessage
- add metadata argument to add_message; add Zep metadata to
Message.additional_kwargs
- support passing in metadata

Add a callback handler for Context (https://getcontext.ai) (#7151)
### Description

Adding a callback handler for Context. Context is a product analytics
platform for AI chat experiences to help you understand how users are
interacting with your product.

I've added the callback library + an example notebook showing its use.

### Dependencies

Requires the user to install the `context-python` library. The library
is lazily-loaded when the callback is instantiated.

### Announcing the feature

We spoke with Harrison a few weeks ago about also doing a blog post
announcing our integration, so will coordinate this with him. Our
Twitter handle for the company is @getcontextai, and the founders are
@_agamble and @HenrySG.

Thanks in advance!

The Fellowship of the Vectors: New Embeddings Filter using clustering. (#7015)
Continuing with Tolkien inspired series of langchain tools. I bring to
you:
**The Fellowship of the Vectors**, AKA EmbeddingsClusteringFilter.
This document filter uses embeddings to group vectors together into
clusters, then allows you to pick an arbitrary number of documents
vector based on proximity to the cluster centers. That's a
representative sample of the cluster.

The original idea is from [Greg Kamradt](https://github.com/gkamradt)
from this video (Level4):
https://www.youtube.com/watch?v=qaPMdcCqtWk&t=365s

I added few tricks to make it a bit more versatile, so you can
parametrize what to do with duplicate documents in case of cluster
overlap: replace the duplicates with the next closest document or remove
it. This allow you to use it as an special kind of redundant filter too.
Additionally you can choose 2 diff orders: grouped by cluster or
respecting the original retriever scores.
In my use case I was using the docs grouped by cluster to run refine
chains per cluster to generate summarization over a large corpus of
documents.
Let me know if you want to change anything!

Marqo Vector Store Examples & Type Hints (#7326)
This PR improves the example notebook for the Marqo vectorstore
implementation by adding a new RetrievalQAWithSourcesChain example. The
`embedding` parameter in `from_documents` has its type updated to
`Union[Embeddings, None]` and a default parameter of None because this
is ignored in Marqo.

This PR also upgrades the Marqo version to 0.11.0 to remove the device
parameter after a breaking change to the API.

docs: update youtube videos and tutorials (#6515)

Rationale: the Tutorials section in the documentation is top-priority.
(for example, https://pytorch.org/docs/stable/index.html) Not every
project has resources to make tutorials. We have such a privilege.
Community experts created several tutorials on YouTube. But the tutorial
links are now hidden on the YouTube page and not easily discovered by
first-time visitors.

- Added new videos and tutorials that were created since the last
update.
- Made some reprioritization between videos on the base of the view
numbers.

Add pg_hnsw vectorstore integration (#6893)
Hi @rlancemartin, @eyurtsev!

- Description: Adding HNSW extension support for Postgres. Similar to
pgvector vectorstore, with 3 differences
      1. it uses HNSW extension for exact and ANN searches, 
      2. Vectors are of type array of real
      3. Only supports L2
      
- Dependencies: [HNSW](https://github.com/knizhnik/hnsw) extension for
Postgres
  
  - Example:
  ```python
    db = HNSWVectoreStore.from_documents(
      embedding=embeddings,
      documents=docs,
      collection_name=collection_name,
      connection_string=connection_string
  )
  
  query = "What did the president say about Ketanji Brown Jackson"
docs_with_score: List[Tuple[Document, float]] =

[Apache HugeGraph](https://github.com/apache/incubator-hugegraph) is a

Apache TinkerPop3 framework and the Gremlin query language.

In this PR, the HugeGraph and HugeGraphQAChain provide the same
functionality as the existing integration with Neo4j and enables query
generation and question answering over HugeGraph database. The
difference is that the graph query language supported by HugeGraph is
not cypher but another very popular graph query language
[Gremlin](https://tinkerpop.apache.org/gremlin.html).

A notebook example and a simple test case have also been added.

It appears `n_ctx` is [no longer a supported
param](https://docs.gpt4all.io/gpt4all_python.html#gpt4all.gpt4all.GPT4All.generate)
in the GPT4All API from https://github.com/nomic-ai/gpt4all/pull/1090.

It now uses `max_tokens`, so I set this.

And I also set other defaults used in GPT4All client
[here](https://github.com/nomic-ai/gpt4all/blob/main/gpt4all-bindings/python/gpt4all/gpt4all.py).

Confirm it now works:
```
$ from langchain.llms import GPT4All
$ model = GPT4All(model=local_path)
$ model("The capital of France is ", max_tokens=10)
< Model logging > 
"....Paris."
```
