This PR addresses a few minor issues with the Cassandra vector store
implementation and extends the store to support Metadata search.
Thanks to the latest cassIO library (>=0.1.0), metadata filtering is
available in the store.
Further,
- the "relevance" score is prevented from being flipped in the [0,1]
interval, thus ensuring that 1 corresponds to the closest vector (this
is related to how the underlying cassIO class returns the cosine
difference);
- bumped the cassIO package version both in the notebooks and the
pyproject.toml;
- adjusted the textfile location for the vector-store example after the
reshuffling of the Langchain repo dir structure;
- added demonstration of metadata filtering in the Cassandra vector
store notebook;
- better docstring for the Cassandra vector store class;
- fixed test flakiness and removed offending out-of-place escape chars
from a test module docstring;
To my knowledge all relevant tests pass and mypy+black+ruff don't
complain. (mypy gives unrelated errors in other modules, which clearly
don't depend on the content of this PR).
Thank you!
Stefano

* More clarity around how geometry is handled. Not returned by default;
when returned, stored in metadata. This is because it's usually a waste
of tokens, but it should be accessible if needed.
* User can supply layer description to avoid errors when layer
properties are inaccessible due to passthrough access.
* Enhanced testing
* Updated notebook

I have revamped the code to ensure uniform error handling for
ImportError. Instead of the previous reliance on ValueError, I have
adopted the conventional practice of raising ImportError and providing
informative error messages. This change enhances code clarity and
clearly signifies that any problems are associated with module imports.
After the refactoring #6570, the DistanceStrategy class was moved to
another module and this introduced a bug into the SingleStoreDB vector
store, as the `DistanceStrategy.EUCLEDIAN_DISTANCE` started to convert
into the 'DistanceStrategy.EUCLEDIAN_DISTANCE' string, instead of just
'EUCLEDIAN_DISTANCE' (same for 'DOT_PRODUCT').
In this change, I check the type of the parameter and use `.name`
attribute to get the correct object's name.

2a4b32dee2/langchain/vectorstores/chroma.py (L355-L375)
Currently, the defined update_document function only takes a single
document and its ID for updating. However, Chroma can update multiple
documents by taking a list of IDs and documents for batch updates. If we
update 'update_document' function both document_id and document can be
`Union[str, List[str]]` but we need to do type check. Because
embed_documents and update functions takes List for text and
document_ids variables. I believe that, writing a new function is the
best option.
I update the Chroma vectorstore with refreshed information from my
website every 20 minutes. Updating the update_document function to
perform simultaneous updates for each changed piece of information would
significantly reduce the update time in such use cases.
For my case I update a total of 8810 chunks. Updating these 8810
individual chunks using the current function takes a total of 8.5
minutes. However, if we process the inputs in batches and update them
collectively, all 8810 separate chunks can be updated in just 1 minute.
This significantly reduces the time it takes for users of actively used
chatbots to access up-to-date information.
I can add an integration test and an example for the documentation for
the new update_document_batch function.

With the latest support for faster cold boot in replicate
https://replicate.com/blog/fine-tune-cold-boots it looks like the
replicate LLM support in langchain is broken since some internal
replicate inputs are being returned.
Screenshot below illustrates the problem:
<img width="1917" alt="image"
src="https://github.com/langchain-ai/langchain/assets/749277/d28c27cc-40fb-4258-8710-844c00d3c2b0">
As you can see, the new replicate_weights param is being sent down with
x-order = 0 (which is causing langchain to use that param instead of
prompt which is x-order = 1)
FYI @baskaryan this requires a fix otherwise replicate is broken for
these models. I have pinged replicate whether they want to fix it on
their end by changing the x-order returned by them.
Update: per suggestion I updated the PR to just allow manually setting
the prompt_key which can be set to "prompt" in this case by callers... I
think this is going to be faster anyway than trying to dynamically query
the model every time if you know the prompt key for your model.

**Description**:
Fixed a bug introduced in version 0.0.281 in
`DynamoDBChatMessageHistory` where `self.table.delete_item(self.key)`
produced a TypeError: `TypeError: delete_item() only accepts keyword
arguments`. Updated the method call to
`self.table.delete_item(Key=self.key)` to resolve this issue.
Please see also [the official AWS
documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/dynamodb/table/delete_item.html#)
on this **delete_item** method - only `**kwargs` are accepted.
See also the PR, which introduced this bug:
https://github.com/langchain-ai/langchain/pull/9896#discussion_r1317899073
Please merge this, I rely on this delete dynamodb item functionality
(because of GDPR considerations).

If loading a CSV from a direct or temporary source, loading the
file-like object (subclass of IOBase) directly allows the agent creation
process to succeed, instead of throwing a ValueError.
Added an additional elif and tweaked value error message.
Added test to validate this functionality.
Pandas from_csv supports this natively but this current implementation
only accepts strings or paths to files.
