Cassandra support for LLM cache (exact-match and semantic) (#9772)
This PR implements two new classes in the cache module: `CassandraCache`
and `CassandraSemanticCache`, similar in structure and functionality to
their Redis counterpart: providing a cache for the response to a
(prompt, llm) pair.

Integration tests are included. Moreover, linting and type checks are
all passing on my machine.

Dependencies: the `pyproject.toml` and `poetry.lock` have the newest
version of cassIO (the very same as in the Cassandra vector store
metadata PR, submitted as #9280).

If I may suggest, this issue and #9280 might be reviewed together (as
they bring the same poetry changes along), so I'm tagging @baskaryan who
already helped out a little with poetry-related conflicts there. (Thank
you!)

I'd be happy to add a short notebook if this is deemed necessary (but it
seems to me that, contrary e.g. to vector stores, caches are not covered
in specific notebooks).

Thank you!

Extend SQLChatMessageHistory (#9849)
### Description

There is a really nice class for saving chat messages into a database -
SQLChatMessageHistory.
It leverages SqlAlchemy to be compatible with any supported database (in
contrast with PostgresChatMessageHistory, which is basically the same
but is limited to Postgres).

However, the class is not really customizable in terms of what you can
store. I can imagine a lot of use cases, when one will need to save a
message date, along with some additional metadata.

To solve this, I propose to extract the converting logic from
BaseMessage to SQLAlchemy model (and vice versa) into a separate class -
message converter. So instead of rewriting the whole
SQLChatMessageHistory class, a user will only need to write a custom
model and a simple mapping class, and pass its instance as a parameter.

I also noticed that there is no documentation on this class, so I added
that too, with an example of custom message converter.

Fix: Nested Dicts Handling of Document Metadata (#9880)
## Description
When the `MultiQueryRetriever` is used to get the list of documents
relevant according to a query, inside a vector store, and at least one
of these contain metadata with nested dictionaries, a `TypeError:
unhashable type: 'dict'` exception is thrown.
This is caused by the `unique_union` function which, to guarantee the
uniqueness of the returned documents, tries, unsuccessfully, to hash the
nested dictionaries and use them as a part of key.
```python
unique_documents_dict = {
    (doc.page_content, tuple(sorted(doc.metadata.items()))): doc
    for doc in documents
}
```

## Issue
#9872 (MultiQueryRetriever (get_relevant_documents) raises TypeError:
unhashable type: 'dict' with dic metadata)

## Solution
A possible solution is to dump the metadata dict to a string and use it
as a part of hashed key.
```python
unique_documents_dict = {
    (doc.page_content, json.dumps(doc.metadata, sort_keys=True)): doc
    for doc in documents
}
```

fix (Html2TextTransformer): allow configuration of html2text (#9914)
Hi, this PR enables configuring the html2text package, instead of being
bound to use the hardcoded values. While simply passing `ignore_links`
and `ignore_images` to the `transform_documents` method was possible, I
preferred passing them to the `__init__` method for 2 reasons:

1. It is more efficient in case of subsequent calls to
`transform_documents`.
2. It allows to move the "complexity" to the instantiation, keeping the
actual execution simple and general enough. IMO the transformers should
all follow this pattern, allowing something like this:
```python
# Instantiate transformers
transformers = [
    TransformerA(foo='bar'),
    TransformerB(bar='foo'),
    # others
]

# During execution, call them sequentially
documents = ...
for tr in transformers:
    documents = tr.transform_documents(documents)
```

Thanks for the reviews!

Takeoff baseurl support (#10091)
## Description
This PR introduces a minor change to the TitanTakeoff integration. 
Instead of specifying a port on localhost, this PR will allow users to
specify a baseURL instead. This will allow users to use the integration
if they have TitanTakeoff deployed externally (not on localhost). This
removes the hardcoded reference to localhost "http://localhost:{port}".

### Info about Titan Takeoff
Titan Takeoff is an inference server created by
[TitanML](https://www.titanml.co/) that allows you to deploy large
language models locally on your hardware in a single command. Most
generative model architectures are included, such as Falcon, Llama 2,
GPT2, T5 and many more.

Read more about Titan Takeoff here:
-
[Blog](https://medium.com/@TitanML/introducing-titan-takeoff-6c30e55a8e1e)
- [Docs](https://docs.titanml.co/docs/titan-takeoff/getting-started)

### Dependencies
No new dependencies are introduced. However, users will need to install
the titan-iris package in their local environment and start the Titan
Takeoff inferencing server in order to use the Titan Takeoff
integration.

Thanks for your help and please let me know if you have any questions.

Add parser and loader for Azure document intelligence service. (#10136)
Hi,

this PR contains loader / parser for Azure Document intelligence which
is a ML-based service to ingest arbitrary PDFs / images, even if
scanned. The loader generates Documents by pages of the original
document. This is my first contribution to LangChain.

Unfortunately I could not find the correct place for test cases. Happy
to add one if you can point me to the location, but as this is a
cloud-based service, a test would require network access and credentials
- so might be of limited help.

Dependencies: The needed dependency was already part of pyproject.toml,
no change.

EdenAI LLM update. Add models name option (#8963)
This PR follows the **Eden AI (LLM + embeddings) integration**. #8633 

We added an optional parameter to choose different AI models for
providers (like 'text-bison' for provider 'google', 'text-davinci-003'
for provider 'openai', etc.).

Usage:

```python
llm = EdenAI(
    feature="text",
    provider="google",
    params={
        "model": "text-bison",  # new
        "temperature": 0.2,
        "max_tokens": 250,
    },
)

```

You can also change the provider + model after initialization
```python
llm = EdenAI(
    feature="text",
    provider="google",
    params={
        "temperature": 0.2,
        "max_tokens": 250,
    },
)

prompt = """
hi 
"""

llm(prompt, providers='openai', model='text-davinci-003')  # change provider & model
```

The jupyter notebook as been updated with an example well.

This PR follows the Eden AI (LLM + embeddings) integration. #8633

We added different Tools to empower agents with new capabilities :

- text: explicit content detection

- image: explicit content detection

- image: object detection

- OCR: invoice parsing

- OCR: ID parsing

- audio: speech to text

- audio: text to speech

 
We plan to add more in the future (like translation, language detection,
+ others).


Usage:

```python
llm=EdenAI(feature="text",provider="openai", params={"temperature" : 0.2,"max_tokens" : 250})

tools = [
    EdenAiTextModerationTool(providers=["openai"],language="en"),
    EdenAiObjectDetectionTool(providers=["google","api4ai"]),
    EdenAiTextToSpeechTool(providers=["amazon"],language="en",voice="MALE"),
    EdenAiExplicitImageTool(providers=["amazon","google"]),
    EdenAiSpeechToTextTool(providers=["amazon"]),
    EdenAiParsingIDTool(providers=["amazon","klippa"],language="en"),
    EdenAiParsingInvoiceTool(providers=["amazon","google"],language="en"),
]

agent_chain = initialize_agent(
    tools,
    llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
    return_intermediate_steps=True,
)

result = agent_chain(""" i have this text : 'i want to slap you' 
                   first : i want to know if this text contains explicit content or not .
                   second : if it does contain explicit content i want to know what is the explicit content in this text, 
                   third : i want to make the text into speech .
                   if there is URL in the observations , you will always put it in the output (final answer) .
                   """)
```

This PR is made in parallel with  EdenAI LLM update #8963 
I apologize for the messy PR. While working in implementing Tools we
realized there was a few problems we needed to fix on LLM as well.

fix (parsers/json): do not escape double quotes if already escaped (#9916)
This PR fixes an issues I found when upgrading to a more recent version
of Langchain. I was using 0.0.142 before, and this issue popped up
already when the `_custom_parser` was added to `output_parsers/json`.

Anyway, the issue is that the parser tries to escape quotes when they
are double-escaped (e.g. `\\"`), leading to OutputParserException.
This is particularly undesired in my app, because I have an Agent that
uses a single input Tool, which expects as input a JSON string with the
structure:
```python
{
    "foo": string,
    "bar": string
}
```
The LLM (GPT3.5) response is (almost) always something like
`"action_input": "{\\"foo\\": \\"bar\\", \\"bar\\": \\"foo\\"}"` and
since the upgrade this is not correctly parsed.

feat: Add `ApifyWrapper` class (#10067)
If you look at documentation
https://python.langchain.com/docs/integrations/tools/apify (or the
actual file
https://github.com/langchain-ai/langchain/blob/master/docs/extras/integrations/tools/apify.ipynb
), there's a class `ApifyWrapper` mentioned. It seems it got lost in
some refactoring, i.e. it does not exist in the codebase ATM.

I just propose to add it back.
It would fix issues e.g.
https://github.com/langchain-ai/langchain/issues/8307 or
https://github.com/langchain-ai/langchain/issues/8201

To add, Apify is a wanted integration, e.g. see
https://twitter.com/hwchase17/status/1695490295914545626 or
https://twitter.com/hwchase17/status/1695470765343461756

Lastly, I offer taking ownership of the Apify-related parts of the
codebase, so you can tag me if anything is needed.

update_forward_refs for Run (#9969)
Adds a call to Pydantic's `update_forward_refs` for the `Run` class (in
addition to the `ChainRun` and `ToolRun` classes, for which that method
is already called). Without it, the self-reference of child classes
(type `List[Run]`) is problematic. For example:

```python
from langchain.callbacks import StdOutCallbackHandler
from langchain.chains import LLMChain
from langchain.llms import OpenAI
from langchain.prompts import PromptTemplate
from wandb.integration.langchain import WandbTracer

llm = OpenAI()
prompt = PromptTemplate.from_template("1 + {number} = ")

chain = LLMChain(llm=llm, prompt=prompt, callbacks=[StdOutCallbackHandler(), WandbTracer()])
print(chain.run(number=2))

```

results in the following output before the change

```
WARNING:root:Error in on_chain_start callback: field "child_runs" not yet prepared so type is still a ForwardRef, you might need to call Run.update_forward_refs().

> Entering new LLMChain chain...
Prompt after formatting:
1 + 2 = 
WARNING:root:Error in on_chain_end callback: No chain Run found to be traced

> Finished chain.

3
```

but afterwards the callback error messages are gone.

implement vectorstores by tencent vectordb (#9989)
Hi there!
I'm excited to open this PR to add support for using 'Tencent Cloud
VectorDB' as a vector store.

Tencent Cloud VectorDB is a fully-managed, self-developed,
enterprise-level distributed database service designed for storing,
retrieving, and analyzing multi-dimensional vector data. The database
supports multiple index types and similarity calculation methods, with a
single index supporting vector scales up to 1 billion and capable of
handling millions of QPS with millisecond-level query latency. Tencent
Cloud VectorDB not only provides external knowledge bases for large
models to improve their accuracy, but also has wide applications in AI
fields such as recommendation systems, NLP services, computer vision,
and intelligent customer service.

The PR includes:
 Implementation of Vectorstore.

I have read your [contributing
guidelines](72b7d76d79/.github/CONTRIBUTING.md).
And I have passed the tests below

refactor(document_loaders): abstract page evaluation logic in PlaywrightURLLoader (#9995)
This PR brings structural updates to `PlaywrightURLLoader`, aiming at
making the code more readable and extensible through the abstraction of
page evaluation logic. These changes also align this implementation with
a similar structure used in LangChain.js.

The key enhancements include:

1. Introduction of 'PlaywrightEvaluator', an abstract base class for all
evaluators.
2. Creation of 'UnstructuredHtmlEvaluator', a concrete class
implementing 'PlaywrightEvaluator', which uses `unstructured` library
for processing page's HTML content.
3. Extension of 'PlaywrightURLLoader' constructor to optionally accept
an evaluator of the type 'PlaywrightEvaluator'. It defaults to
'UnstructuredHtmlEvaluator' if no evaluator is provided.
4. Refactoring of 'load' and 'aload' methods to use the 'evaluate' and
'evaluate_async' methods of the provided 'PageEvaluator' for page
content handling.

This update brings flexibility to 'PlaywrightURLLoader' as it can now
utilize different evaluators for page processing depending on the
requirement. The abstraction also improves code maintainability and
readability.

Add data anonymizer (#9863)
### Description

The feature for anonymizing data has been implemented. In order to
protect private data, such as when querying external APIs (OpenAI), it
is worth pseudonymizing sensitive data to maintain full privacy.

Anonynization consists of two steps:

1. **Identification:** Identify all data fields that contain personally
identifiable information (PII).
2. **Replacement**: Replace all PIIs with pseudo values or codes that do
not reveal any personal information about the individual but can be used
for reference. We're not using regular encryption, because the language
model won't be able to understand the meaning or context of the
encrypted data.

We use *Microsoft Presidio* together with *Faker* framework for
anonymization purposes because of the wide range of functionalities they
provide. The full implementation is available in `PresidioAnonymizer`.

### Future works

- **deanonymization** - add the ability to reverse anonymization. For
example, the workflow could look like this: `anonymize -> LLMChain ->
deanonymize`. By doing this, we will retain anonymity in requests to,
for example, OpenAI, and then be able restore the original data.
- **instance anonymization** - at this point, each occurrence of PII is
treated as a separate entity and separately anonymized. Therefore, two
occurrences of the name John Doe in the text will be changed to two
different names. It is therefore worth introducing support for full
instance detection, so that repeated occurrences are treated as a single
object.

Clearly document that the PAL and CPAL techniques involve generating

While our implementations include some mitigations, Python and SQL
sandboxing is well-known to be a very hard problem and our mitigations
are no replacement for proper sandboxing and permissions management. The
implementation of such techniques must be performed outside the scope of
the Python process where this package's code runs, so its correct setup
and administration must therefore be the responsibility of the user of
this code.

Avoid `type: ignore` suppression by adding mypy type hint. (#9881)
Mypy was not able to determine a good type for `type_to_loader_dict`,
since the values in the dict are functions whose return types are
related to each other in a complex way. One can see this by adding a
line like `reveal_type(type_to_loader_dict)` and running mypy, which
will get mypy to show what type it has inferred for that value.

Adding an explicit type hint to help out mypy avoids the need for a mypy
suppression and allows the code to type-check cleanly.

feat: grammar-based sampling in llama-cpp (#9712)
## Description 

The following PR enables the [grammar-based
sampling](https://github.com/ggerganov/llama.cpp/tree/master/grammars)
in llama-cpp LLM.

In short, loading file with formal grammar definition will constrain
model outputs. For instance, one can force the model to generate valid
JSON or generate only python lists.

In the follow-up PR we will add:
* docs with some description why it is cool and how it works
* maybe some code sample for some task such as in llama repo

Redis metadata filtering and specification, index customization (#8612)
### Description

The previous Redis implementation did not allow for the user to specify
the index configuration (i.e. changing the underlying algorithm) or add
additional metadata to use for querying (i.e. hybrid or "filtered"
search).

This PR introduces the ability to specify custom index attributes and
metadata attributes as well as use that metadata in filtered queries.
Overall, more structure was introduced to the Redis implementation that
should allow for easier maintainability moving forward.

# New Features

The following features are now available with the Redis integration into
Langchain

## Index schema generation

The schema for the index will now be automatically generated if not
specified by the user. For example, the data above has the multiple
metadata categories. The the following example

```python

from langchain.embeddings import OpenAIEmbeddings
from langchain.vectorstores.redis import Redis

embeddings = OpenAIEmbeddings()


rds, keys = Redis.from_texts_return_keys(
    texts,
    embeddings,
    metadatas=metadata,
    redis_url="redis://localhost:6379",
    index_name="users"
)
```

Loading the data in through this and the other ``from_documents`` and
``from_texts`` methods will now generate index schema in Redis like the
following.

view index schema with the ``redisvl`` tool. [link](redisvl.com)

```bash
$ rvl index info -i users
```


Index Information:
| Index Name | Storage Type | Prefixes | Index Options | Indexing |

|--------------|----------------|---------------|-----------------|------------|
| users | HASH | ['doc:users'] | [] | 0 |
Index Fields:
| Name | Attribute | Type | Field Option | Option Value |

|----------------|----------------|---------|----------------|----------------|
| user | user | TEXT | WEIGHT | 1 |
| job | job | TEXT | WEIGHT | 1 |
| credit_score | credit_score | TEXT | WEIGHT | 1 |
| content | content | TEXT | WEIGHT | 1 |
| age | age | NUMERIC | | |
| content_vector | content_vector | VECTOR | | |


### Custom Metadata specification

The metadata schema generation has the following rules
1. All text fields are indexed as text fields.
2. All numeric fields are index as numeric fields.

If you would like to have a text field as a tag field, users can specify
overrides like the following for the example data

```python

# this can also be a path to a yaml file
index_schema = {
    "text": [{"name": "user"}, {"name": "job"}],
    "tag": [{"name": "credit_score"}],
    "numeric": [{"name": "age"}],
}

rds, keys = Redis.from_texts_return_keys(
    texts,
    embeddings,
    metadatas=metadata,
    redis_url="redis://localhost:6379",
    index_name="users"
)
```
This will change the index specification to 

Index Information:
| Index Name | Storage Type | Prefixes | Index Options | Indexing |

|--------------|----------------|----------------|-----------------|------------|
| users2 | HASH | ['doc:users2'] | [] | 0 |
Index Fields:
| Name | Attribute | Type | Field Option | Option Value |

|----------------|----------------|---------|----------------|----------------|
| user | user | TEXT | WEIGHT | 1 |
| job | job | TEXT | WEIGHT | 1 |
| content | content | TEXT | WEIGHT | 1 |
| credit_score | credit_score | TAG | SEPARATOR | , |
| age | age | NUMERIC | | |
| content_vector | content_vector | VECTOR | | |


and throw a warning to the user (log output) that the generated schema
does not match the specified schema.

```text
index_schema does not match generated schema from metadata.
index_schema: {'text': [{'name': 'user'}, {'name': 'job'}], 'tag': [{'name': 'credit_score'}], 'numeric': [{'name': 'age'}]}
generated_schema: {'text': [{'name': 'user'}, {'name': 'job'}, {'name': 'credit_score'}], 'numeric': [{'name': 'age'}]}
```

As long as this is on purpose,  this is fine.

The schema can be defined as a yaml file or a dictionary

```yaml

text:
  - name: user
  - name: job
tag:
  - name: credit_score
numeric:
  - name: age

```

and you pass in a path like

```python
rds, keys = Redis.from_texts_return_keys(
    texts,
    embeddings,
    metadatas=metadata,
    redis_url="redis://localhost:6379",
    index_name="users3",
    index_schema=Path("sample1.yml").resolve()
)
```

Which will create the same schema as defined in the dictionary example


Index Information:
| Index Name | Storage Type | Prefixes | Index Options | Indexing |

|--------------|----------------|----------------|-----------------|------------|
| users3 | HASH | ['doc:users3'] | [] | 0 |
Index Fields:
| Name | Attribute | Type | Field Option | Option Value |

|----------------|----------------|---------|----------------|----------------|
| user | user | TEXT | WEIGHT | 1 |
| job | job | TEXT | WEIGHT | 1 |
| content | content | TEXT | WEIGHT | 1 |
| credit_score | credit_score | TAG | SEPARATOR | , |
| age | age | NUMERIC | | |
| content_vector | content_vector | VECTOR | | |



### Custom Vector Indexing Schema

Users with large use cases may want to change how they formulate the
vector index created by Langchain

To utilize all the features of Redis for vector database use cases like
this, you can now do the following to pass in index attribute modifiers
like changing the indexing algorithm to HNSW.

```python
vector_schema = {
    "algorithm": "HNSW"
}

rds, keys = Redis.from_texts_return_keys(
    texts,
    embeddings,
    metadatas=metadata,
    redis_url="redis://localhost:6379",
    index_name="users3",
    vector_schema=vector_schema
)

```

A more complex example may look like

```python
vector_schema = {
    "algorithm": "HNSW",
    "ef_construction": 200,
    "ef_runtime": 20
}

rds, keys = Redis.from_texts_return_keys(
    texts,
    embeddings,
    metadatas=metadata,
    redis_url="redis://localhost:6379",
    index_name="users3",
    vector_schema=vector_schema
)
```

All names correspond to the arguments you would set if using Redis-py or
RedisVL. (put in doc link later)


### Better Querying

Both vector queries and Range (limit) queries are now available and
metadata is returned by default. The outputs are shown.

```python
>>> query = "foo"
>>> results = rds.similarity_search(query, k=1)
>>> print(results)
[Document(page_content='foo', metadata={'user': 'derrick', 'job': 'doctor', 'credit_score': 'low', 'age': '14', 'id': 'doc:users:657a47d7db8b447e88598b83da879b9d', 'score': '7.15255737305e-07'})]

>>> results = rds.similarity_search_with_score(query, k=1, return_metadata=False)
>>> print(results) # no metadata, but with scores
[(Document(page_content='foo', metadata={}), 7.15255737305e-07)]

>>> results = rds.similarity_search_limit_score(query, k=6, score_threshold=0.0001)
>>> print(len(results)) # range query (only above threshold even if k is higher)
4
```

### Custom metadata filtering

A big advantage of Redis in this space is being able to do filtering on
data stored alongside the vector itself. With the example above, the
following is now possible in langchain. The equivalence operators are
overridden to describe a new expression language that mimic that of
[redisvl](redisvl.com). This allows for arbitrarily long sequences of
filters that resemble SQL commands that can be used directly with vector
queries and range queries.

There are two interfaces by which to do so and both are shown. 

```python

>>> from langchain.vectorstores.redis import RedisFilter, RedisNum, RedisText

>>> age_filter = RedisFilter.num("age") > 18
>>> age_filter = RedisNum("age") > 18 # equivalent
>>> results = rds.similarity_search(query, filter=age_filter)
>>> print(len(results))
3

>>> job_filter = RedisFilter.text("job") == "engineer" 
>>> job_filter = RedisText("job") == "engineer" # equivalent
>>> results = rds.similarity_search(query, filter=job_filter)
>>> print(len(results))
2

# fuzzy match text search
>>> job_filter = RedisFilter.text("job") % "eng*"
>>> results = rds.similarity_search(query, filter=job_filter)
>>> print(len(results))
2


# combined filters (AND)
>>> combined = age_filter & job_filter
>>> results = rds.similarity_search(query, filter=combined)
>>> print(len(results))
1

# combined filters (OR)
>>> combined = age_filter | job_filter
>>> results = rds.similarity_search(query, filter=combined)
>>> print(len(results))
4
```

All the above filter results can be checked against the data above.

Initial commit for comprehend moderator (#9665)
This PR implements a custom chain that wraps Amazon Comprehend API
calls. The custom chain is aimed to be used with LLM chains to provide
moderation capability that let’s you detect and redact PII, Toxic and
Intent content in the LLM prompt, or the LLM response. The
implementation accepts a configuration object to control what checks
will be performed on a LLM prompt and can be used in a variety of setups
using the LangChain expression language to not only detect the
configured info in chains, but also other constructs such as a
retriever.
The included sample notebook goes over the different configuration
options and how to use it with other chains.

###  Usage sample
```python
from langchain_experimental.comprehend_moderation import BaseModerationActions, BaseModerationFilters

moderation_config = { 
        "filters":[ 
                BaseModerationFilters.PII, 
                BaseModerationFilters.TOXICITY,
                BaseModerationFilters.INTENT
        ],
        "pii":{ 
                "action": BaseModerationActions.ALLOW, 
                "threshold":0.5, 
                "labels":["SSN"],
                "mask_character": "X"
        },
        "toxicity":{ 
                "action": BaseModerationActions.STOP, 
                "threshold":0.5
        },
        "intent":{ 
                "action": BaseModerationActions.STOP, 
                "threshold":0.5
        }
}

comp_moderation_with_config = AmazonComprehendModerationChain(
    moderation_config=moderation_config, #specify the configuration
    client=comprehend_client,            #optionally pass the Boto3 Client
    verbose=True
)

template = """Question: {question}

Answer:"""

prompt = PromptTemplate(template=template, input_variables=["question"])

responses = [
    "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", 
    "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here."
]
llm = FakeListLLM(responses=responses)

llm_chain = LLMChain(prompt=prompt, llm=llm)

chain = ( 
    prompt 
    | comp_moderation_with_config 
    | {llm_chain.input_keys[0]: lambda x: x['output'] }  
    | llm_chain 
    | { "input": lambda x: x['text'] } 
    | comp_moderation_with_config 
)

response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"})

print(response['output'])


```
### Output
```
> Entering new AmazonComprehendModerationChain chain...
Running AmazonComprehendModerationChain...
Running pii validation...
Found PII content..stopping..
The prompt contains PII entities and cannot be processed
```

Fix QuestionListOutputParser (#9738)
This PR fixes `QuestionListOutputParser` text splitting.

`QuestionListOutputParser` incorrectly splits numbered list text into
lines. If text doesn't end with `\n` , the regex doesn't capture the
last item. So it always returns `n - 1` items, and
`WebResearchRetriever.llm_chain` generates less queries than requested
in the search prompt.

How to reproduce:

```python
from langchain.retrievers.web_research import QuestionListOutputParser

parser = QuestionListOutputParser()

good = parser.parse(
    """1. This is line one.
    2. This is line two.
    """  # <-- !
)

bad = parser.parse(
    """1. This is line one.
    2. This is line two."""    # <-- No new line.
)

assert good.lines == ['1. This is line one.\n', '2. This is line two.\n'], good.lines
assert bad.lines == ['1. This is line one.\n', '2. This is line two.'], bad.lines
```

NOTE: Last item will not contain a line break but this seems ok because
the items are stripped in the
`WebResearchRetriever.clean_search_query()`.

provide a utility function to map these to ai and human messages
- Going to move the discord one into just a notebook since I don't have

Add the option to use separate LLMs for GraphCypherQA chain (#9689)
The Graph Chains are different in the way that it uses two LLMChains
instead of one like the retrievalQA chains. Therefore, sometimes you
want to use different LLM to generate the database query and to generate
the final answer.

This feature would make it more convenient to use different LLMs in the
same chain.

I have also renamed the Graph DB QA Chain to Neo4j DB QA Chain in the
documentation only as it is used only for Neo4j. The naming was
ambigious as it was the first graphQA chain added and wasn't sure how do
you want to spin it.

This PR adds a new document loader `AssemblyAIAudioTranscriptLoader`
that allows to transcribe audio files with the [AssemblyAI
API](https://www.assemblyai.com) and loads the transcribed text into
documents.

- Add new document_loader with class `AssemblyAIAudioTranscriptLoader`
- Add optional dependency `assemblyai`
- Add unit tests (using a Mock client)
- Add docs notebook

This is the equivalent to the JS integration already available in
LangChain.js. See the [LangChain JS docs AssemblyAI
page](https://js.langchain.com/docs/modules/data_connection/document_loaders/integrations/web_loaders/assemblyai_audio_transcription).

At its simplest, you can use the loader to get a transcript back from an
audio file like this:

```python
from langchain.document_loaders.assemblyai import AssemblyAIAudioTranscriptLoader

loader =  AssemblyAIAudioTranscriptLoader(file_path="./testfile.mp3")
docs = loader.load()
```

To use it, it needs the `assemblyai` python package installed, and the
environment variable `ASSEMBLYAI_API_KEY` set with your API key.
Alternatively, the API key can also be passed as an argument.

Add indexing support (#9614)
This PR introduces a persistence layer to help with indexing workflows
into
vectostores.

The indexing code helps users to:

1. Avoid writing duplicated content into the vectostore
2. Avoid over-writing content if it's unchanged

Importantly, this keeps on working even if the content being written is
derived
via a set of transformations from some source content (e.g., indexing
children
documents that were derived from parent documents by chunking.)

The two main components are:

1. Persistence layer that keeps track of which keys were updated and
when.
Keeping track of the timestamp of updates, allows to clean up old
content
   safely, and with minimal complexity.
2. HashedDocument which is used to hash the contents (including
metadata) of
   the documents. We rely on the hashes for identifying duplicates.


The indexing code works with **ANY** document loader. To add
transformations
to the documents, users for now can add a custom document loader
that composes an existing loader together with document transformers.

Anthropic: Allow the use of kwargs consistent with ChatOpenAI. (#9515)
- Description: ~~Creates a new root_validator in `_AnthropicCommon` that
allows the use of `model_name` and `max_tokens` keyword arguments.~~
Adds pydantic field aliases to support `model_name` and `max_tokens` as
keyword arguments. Ultimately, this makes `ChatAnthropic` more
consistent with `ChatOpenAI`, making the two classes more
interchangeable for the developer.
  - Issue: https://github.com/langchain-ai/langchain/issues/9510
