As the title says, I added more code splitters.
The implementation is trivial, so i don't add separate tests for each
splitter.
Let me know if any concerns.

# Add ToolException that a tool can throw
This is an optional exception that tool throws when execution error
occurs.
When this exception is thrown, the agent will not stop working,but will
handle the exception according to the handle_tool_error variable of the
tool,and the processing result will be returned to the agent as
observation,and printed in pink on the console.It can be used like this:
```python
from langchain.schema import ToolException
from langchain import LLMMathChain, SerpAPIWrapper, OpenAI
from langchain.agents import AgentType, initialize_agent
from langchain.chat_models import ChatOpenAI
from langchain.tools import BaseTool, StructuredTool, Tool, tool
from langchain.chat_models import ChatOpenAI
llm = ChatOpenAI(temperature=0)
llm_math_chain = LLMMathChain(llm=llm, verbose=True)
class Error_tool:
def run(self, s: str):
raise ToolException('The current search tool is not available.')
def handle_tool_error(error) -> str:
return "The following errors occurred during tool execution:"+str(error)
search_tool1 = Error_tool()
search_tool2 = SerpAPIWrapper()
tools = [
Tool.from_function(
func=search_tool1.run,
name="Search_tool1",
description="useful for when you need to answer questions about current events.You should give priority to using it.",
handle_tool_error=handle_tool_error,
),
Tool.from_function(
func=search_tool2.run,
name="Search_tool2",
description="useful for when you need to answer questions about current events",
return_direct=True,
)
]
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True,
handle_tool_errors=handle_tool_error)
agent.run("Who is Leo DiCaprio's girlfriend? What is her current age raised to the 0.43 power?")
```

# docs: ecosystem/integrations update
It is the first in a series of `ecosystem/integrations` updates.
The ecosystem/integrations list is missing many integrations.
I'm adding the missing integrations in a consistent format:
1. description of the integrated system
2. `Installation and Setup` section with 'pip install ...`, Key setup,
and other necessary settings
3. Sections like `LLM`, `Text Embedding Models`, `Chat Models`... with
links to correspondent examples and imports of the used classes.
This PR keeps new docs, that are presented in the
`docs/modules/models/text_embedding/examples` but missed in the
`ecosystem/integrations`. The next PRs will cover the next example
sections.
Also updated `integrations.rst`: added the `Dependencies` section with a
link to the packages used in LangChain.

# Fix for `update_document` Function in Chroma
## Summary
This pull request addresses an issue with the `update_document` function
in the Chroma class, as described in
[#5031](https://github.com/hwchase17/langchain/issues/5031#issuecomment-1562577947).
The issue was identified as an `AttributeError` raised when calling
`update_document` due to a missing corresponding method in the
`Collection` object. This fix refactors the `update_document` method in
`Chroma` to correctly interact with the `Collection` object.
## Changes
1. Fixed the `update_document` method in the `Chroma` class to correctly
call methods on the `Collection` object.
2. Added the corresponding test `test_chroma_update_document` in
`tests/integration_tests/vectorstores/test_chroma.py` to reflect the
updated method call.
3. Added an example and explanation of how to use the `update_document`
function in the Jupyter notebook tutorial for Chroma.
## Test Plan
All existing tests pass after this change. In addition, the
`test_chroma_update_document` test case now correctly checks the
functionality of `update_document`, ensuring that the function works as
expected and updates the content of documents correctly.
## Reviewers
@dev2049
This fix will ensure that users are able to use the `update_document`
function as expected, without encountering the previous
`AttributeError`. This will enhance the usability and reliability of the
Chroma class for all users.
Thank you for considering this pull request. I look forward to your
feedback and suggestions.
# Add async support for (LLM) routing chains

<!-- Remove if not applicable -->
Add asynchronous LLM calls support for the routing chains. More
specifically:
- Add async `aroute` function (i.e. async version of `route`) to the
`RouterChain` which calls the routing LLM asynchronously
- Implement the async `_acall` for the `LLMRouterChain`
- Implement the async `_acall` function for `MultiRouteChain` which
first calls asynchronously the routing chain with its new `aroute`
function, and then calls asynchronously the relevant destination chain.

# Fix lost mimetype when using Blob.from_data method
The mimetype is lost due to a typo in the class attribue name
Fixes # - (no issue opened but I can open one if needed)
## Changes
* Fixed typo in name
* Added unit-tests to validate the output Blob
## Review
@eyurtsev
We shouldn't be calling a constructor for a default value - should use
default_factory instead. This is especially ad in this case since it
requires an optional dependency and an API key to be set.
Resolves#5361
# Fix: Handle empty documents in ContextualCompressionRetriever (Issue
#5304)
Fixes#5304
Prevent cohere.error.CohereAPIError caused by an empty list of documents
by adding a condition to check if the input documents list is empty in
the compress_documents method. If the list is empty, return an empty
list immediately, avoiding the error and unnecessary processing.

# Add path validation to DirectoryLoader
This PR introduces a minor adjustment to the DirectoryLoader by adding
validation for the path argument. Previously, if the provided path
didn't exist or wasn't a directory, DirectoryLoader would return an
empty document list due to the behavior of the `glob` method. This could
potentially cause confusion for users, as they might expect a
file-loading error instead.
So, I've added two validations to the load method of the
DirectoryLoader:
- Raise a FileNotFoundError if the provided path does not exist
- Raise a ValueError if the provided path is not a directory
Due to the relatively small scope of these changes, a new issue was not
created.

# Add SKLearnVectorStore
This PR adds SKLearnVectorStore, a simply vector store based on
NearestNeighbors implementations in the scikit-learn package. This
provides a simple drop-in vector store implementation with minimal
dependencies (scikit-learn is typically installed in a data scientist /
ml engineer environment). The vector store can be persisted and loaded
from json, bson and parquet format.
SKLearnVectorStore has soft (dynamic) dependency on the scikit-learn,
numpy and pandas packages. Persisting to bson requires the bson package,
persisting to parquet requires the pyarrow package.
## Before submitting
Integration tests are provided under
`tests/integration_tests/vectorstores/test_sklearn.py`

Let's say the text given to `GenerativeAgent._parse_list` is
```
text = """
Insight 1: <insight 1>
Insight 2: <insight 2>
"""
```
This creates an `openai.error.InvalidRequestError: [''] is not valid
under any of the given schemas - 'input'` because
`GenerativeAgent.add_memory()` tries to add an empty string to the
vectorstore.
This PR fixes the issue by removing the empty line between `Insight 1`
and `Insight 2`

Thought:
Observation: Invalid or incomplete response
Thought:
Observation: Invalid or incomplete response
Thought:
```
After Fix:
```
Observation: There are 38175 accounts available in the dataframe.
Thought:AI: {
"action": "Final Answer",
"action_input": "There are 38175 accounts available in the dataframe."
}
Observation: Invalid Action or Action Input format
Thought:AI: {
"action": "Final Answer",
"action_input": "The number of available accounts is 38175."
}
Observation: Invalid Action or Action Input format
```
@vowelparrot currently I have set the colour of thought to green (same
as the colour when `handle_parsing_errors=False`). If you want to change
the colour of this "_Exception" case to red or something else (when
`handle_parsing_errors=True`), feel free to change it in line 789.

# docs: improve flow of llm caching notebook
The notebook `llm_caching` demos various caching providers. In the
previous version, there was setup common to all examples but under the
`In Memory Caching` heading.
If a user comes and only wants to try a particular example, they will
run the common setup, then the cells for the specific provider they are
interested in. Then they will get import and variable reference errors.
This commit moves the common setup to the top to avoid this.
