and [Databricks
LLM](https://python.langchain.com/en/latest/modules/models/llms/integrations/databricks.html),
we suggestted users to set the ENV variable `DATABRICKS_API_TOKEN`.
However, this is inconsistent with the other Databricks library. To make
it consistent, this PR changes the variable from `DATABRICKS_API_TOKEN`
to `DATABRICKS_TOKEN`

After changes, there is no more `DATABRICKS_API_TOKEN` in the doc

Use client from LCP-SDK (#5695)
- Remove the client implementation (this breaks backwards compatibility
for existing testers. I could keep the stub in that file if we want, but
not many people are using it yet
- Add SDK as dependency
- Update the 'run_on_dataset' method to be a function that optionally
accepts a client as an argument
- Remove the langchain plus server implementation (you get it for free
with the SDK now)

We could make the SDK optional for now, but the plan is to use w/in the
tracer so it would likely become a hard dependency at some point.

Scores are explained in vectorestore docs (#5613)
# Scores in Vectorestores' Docs Are Explained

Following vectorestores can return scores with similar documents by
using `similarity_search_with_score`:
- chroma
- docarray_hnsw
- docarray_in_memory
- faiss
- myscale
- qdrant
- supabase
- vectara
- weaviate

However, in documents, these scores were either not explained at all or
explained in a way that could lead to misunderstandings (e.g., FAISS).
For instance in FAISS document: if we consider the score returned by the
function as a similarity score, we understand that a document returning
a higher score is more similar to the source document. However, since
the scores returned by the function are distance scores, we should
understand that smaller scores correspond to more similar documents.

For the libraries other than Vectara, I wrote the scores they use by
investigating from the source libraries. Since I couldn't be certain
about the score metric used by Vectara, I didn't make any changes in its
documentation. The links mentioned in Vectara's documentation became
broken due to updates, so I replaced them with working ones.

Add aviary support (#5661)
Aviary is an open source toolkit for evaluating and deploying open
source LLMs. You can find out more about it on
[http://github.com/ray-project/aviary). You can try it out at
[http://aviary.anyscale.com](aviary.anyscale.com).

This code adds support for Aviary in LangChain. To minimize
dependencies, it connects directly to the HTTP endpoint.

The current implementation is not accelerated and uses the default
implementation of `predict` and `generate`.

It includes a test and a simple example. 

@hwchase17 and @agola11 could you have a look at this?

Adding a class attribute "return_generated_question" to class
"BaseConversationalRetrievalChain". If set to `True`, the chain's output
has a key "generated_question" with the question generated by the
sub-chain `question_generator` as the value. This way the generated
question can be logged.

#### Description

This PR is mainly to integrate open source version of ClickHouse as
Vector Store as it is easy for both local development and adoption of
LangChain for enterprises who already have large scale clickhouse
deployment.

ClickHouse is a open source real-time OLAP database with full SQL
support and a wide range of functions to assist users in writing
analytical queries. Some of these functions and data structures perform
distance operations between vectors, [enabling ClickHouse to be used as
a vector
database](https://clickhouse.com/blog/vector-search-clickhouse-p1).
Recently added ClickHouse capabilities like [Approximate Nearest
Neighbour (ANN)
indices](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/annindexes)
support faster approximate matching of vectors and provide a promising
development aimed to further enhance the vector matching capabilities of
ClickHouse.

In LangChain, some ClickHouse based commercial variant vector stores
like
[Chroma](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/chroma.py)
and
[MyScale](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/myscale.py),
etc are already integrated, but for some enterprises with large scale
Clickhouse clusters deployment, it will be more straightforward to
upgrade existing clickhouse infra instead of moving to another similar
vector store solution, so we believe it's a valid requirement to
integrate open source version of ClickHouse as vector store.

As `clickhouse-connect` is already included by other integrations, this
PR won't include any new dependencies.

#### Before submitting

<!-- If you're adding a new integration, please include:

Cypher search: Check if generated Cypher is provided in backticks (#5541)
# Check if generated Cypher code is wrapped in backticks

Some LLMs like the VertexAI like to explain how they generated the
Cypher statement and wrap the actual code in three backticks:

![Screenshot from 2023-06-01
08-08-23](https://github.com/hwchase17/langchain/assets/19948365/1d8eecb3-d26c-4882-8f5b-6a9bc7e93690)


I have observed a similar pattern with OpenAI chat models in a
conversational settings, where multiple user and assistant message are
provided to the LLM to generate Cypher statements, where then the LLM
wants to maybe apologize for previous steps or explain its thoughts.
Interestingly, both OpenAI and VertexAI wrap the code in three backticks
if they are doing any explaining or apologizing. Checking if the
generated cypher is wrapped in backticks seems like a low-hanging fruit
to expand the cypher search to other LLMs and conversational settings.

Addresses GPT4All wrapper model_type attribute issues #5720. (#5743)
Fixes #5720.

A more in-depth discussion is in my comment here:
https://github.com/hwchase17/langchain/issues/5720#issuecomment-1577047018

In a nutshell, there has been a subtle change in the latest version of
GPT4Alls Python bindings. The change I submitted yesterday is compatible
with this version, however, this version is as of yet unreleased and
thus the code change breaks Langchain's wrapper under the currently
released version of GPT4All.

This pull request proposes a backwards-compatible solution.

The current TokenTextSplitter only works with OpenAi models via the

In this (first PR) a token based text splitter for sentence transformer
models is added. In the future I think we should work towards injecting
a tokenizer into the TokenTextSplitter to make ti more flexible.

Raise an exception in MKRL and Chat Output Parsers if parsing text which contains both an action and a final answer (#5609)
Raises exception if OutputParsers receive a response with both a valid
action and a final answer

Currently, if an OutputParser receives a response which includes both an
action and a final answer, they return a FinalAnswer object. This allows
the parser to accept responses which propose an action and hallucinate
an answer without the action being parsed or taken by the agent.

This PR changes the logic to:
1. store a variable checking whether a response contains the
`FINAL_ANSWER_ACTION` (this is the easier condition to check).
2. store a variable checking whether the response contains a valid
action
3. if both are present, raise a new exception stating that both are
present
4. if an action is present, return an AgentAction
5. if an answer is present, return an AgentAnswer
6. if neither is present, raise the relevant exception based around the
action format (these have been kept consistent with the prior exception
messages)

Disclaimer:
* Existing mock data included strings which did include an action and an
answer. This might indicate that prioritising returning AgentAnswer was
always correct, and I am patching out desired behaviour? @hwchase17 to
advice. Curious if there are allowed cases where this is not
hallucinating, and we do want the LLM to output an action which isn't
taken.
* I have not passed `send_to_llm` through this new exception

Fixes #5601

SQL agent : Improved prompt engineering prevents agent guessing database column names. (#5671)
@vowelparrot:

Minor change to the SQL agent:

Tells agent to introspect the schema of the most relevant tables, I
found this to dramatically decrease the chance that the agent wastes
times guessing column names.

Support similarity_score_threshold retrieval with Chroma (#5655)
Fixes https://github.com/hwchase17/langchain/issues/5067

Verified the following code now works correctly:
```
db = Chroma(persist_directory=index_directory(index_name), embedding_function=embeddings)
retriever = db.as_retriever(search_type="similarity_score_threshold", search_kwargs={"score_threshold": 0.4})
docs = retriever.get_relevant_documents(query)

Improve Error Messaging for APOC Procedure Failure in Neo4jGraph (#5547)
## Improve Error Messaging for APOC Procedure Failure in Neo4jGraph

This commit revises the error message provided when the
'apoc.meta.data()' procedure fails. Previously, the message simply
instructed the user to install the APOC plugin in Neo4j. The new error
message is more specific.

Also removed an unnecessary newline in the Cypher statement variable:
`node_properties_query`.

Fixes #5545

Update youtube.py - Fix metadata validation error in YoutubeLoader (#5479)
This commit addresses a ValueError occurring when the YoutubeLoader
class tries to add datetime metadata from a YouTube video's publish
date. The error was happening because the ChromaDB metadata validation
only accepts str, int, or float data types.

In the `_get_video_info` method of the `YoutubeLoader` class, the
publish date retrieved from the YouTube video was of datetime type. This
commit fixes the issue by converting the datetime object to a string
before adding it to the metadata dictionary.

Additionally, this commit introduces error handling in the
`_get_video_info` method to ensure that all metadata fields have valid
values. If a metadata field is found to be None, a default value is
assigned. This prevents potential errors during metadata validation when
metadata fields are None.

The file modified in this commit is youtube.py.

refactor: BaseStringMessagePromptTemplate from_template method (#5332)
# refactor BaseStringMessagePromptTemplate from_template method 

Refactor the `from_template` method of the
`BaseStringMessagePromptTemplate` class to allow passing keyword
arguments to the `from_template` method of `PromptTemplate`.
Enable the usage of arguments like `template_format`.
In my scenario, I intend to utilize Jinja2 for formatting the human
message prompt in the chat template.

FileCallbackHandler (#5589)
# like
[StdoutCallbackHandler](https://github.com/hwchase17/langchain/blob/master/langchain/callbacks/stdout.py),
but writes to a file

When running experiments I have found myself wanting to log the outputs
of my chains in a more lightweight way than using WandB tracing. This PR
contributes a callback handler that writes to file what
`StdoutCallbackHandler` would print.

Created fix for 5475 (#5659)
Created fix for 5475
Currently in PGvector, we do not have any function that returns the
instance of an existing store. The from_documents always adds embeddings
and then returns the store. This fix is to add a function that will
return the instance of an existing store

Also changed the jupyter example for PGVector to show the example of
using the function
