We are unable to run `from langchain.vectorstores import FAISS` with SQLAlchemy <1.4.0 due to top-level imports, even if we aren't even using parts of the library that use SQLAlchemy. See Testing section for repro. Let's make it so that langchain is still compatible with SQLAlchemy <1.4.0, especially if we aren't using parts of langchain that require it. The main conflict is that SQLAlchemy removed `declarative_base` from `sqlalchemy.ext.declarative` in 1.4.0 and moved it to `sqlalchemy.orm`. We can fix this by try-catching the import. This is the same fix as applied in https://github.com/langchain-ai/langchain/pull/883. (I see that there seems to be some refactoring going on about isolating dependencies, e.g. `c87e9fb2ce`, so if this issue will be eventually fixed by isolating imports in langchain.vectorstores that also works). ## Issue I can't find a matching issue. ## Dependencies No additional dependencies ## Maintainer @hwchase17 since you reviewed https://github.com/langchain-ai/langchain/pull/883 ## Testing I didn't add a test, but I manually tested this. 1.

Bagatur	b499de2926	Anthropic system message fix (#11301 ) Removes human prompt prefix before system message for anthropic models Bedrock anthropic api enforces that Human and Assistant messages must be interleaved (cannot have same type twice in a row). We currently treat System Messages as human messages when converting messages -> string prompt. Our validation when using Bedrock/BedrockChat raises an error when this happens. For ChatAnthropic we don't validate this so no error is raised, but perhaps the behavior is still suboptimal	12 months ago
Anatolii Kmetiuk	34a64101cc	Add explanations to GoogleDriveLoader how to avoid errors (#11335 ) - Description: add a paragraph to the GoogleDriveLoader doc on how to bypass errors on authentication. For some reason, specifying credential path via `credentials_path` constructor parameter when creating `GoogleDriveLoader` makes it so that the oAuth screen is never showing up when first using GoogleDriveLoader. Instead, the `RefreshError: ('invalid_grant: Bad Request', {'error': 'invalid_grant', 'error_description': 'Bad Request'})` error happens. Setting it via `os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = ...` solves the problem. Also, `token_path` constructor parameter is mandatory, otherwise another error happens when trying to `load()` for the first time. These errors are tricky and time-consuming to figure out, so I believe it's good to mention them in the docs. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	12 months ago
Massimiliano Angelino	2f83350eac	Feat bedrock cohere support (#11230 ) Description: Added support for Cohere command model via Bedrock. With this change it is now possible to use the `cohere.command-text-v14` model via Bedrock API. About Streaming: Cohere model outputs 2 additional chunks at the end of the text being generated via streaming: a chunk containing the text `<EOS_TOKEN>`, and a chunk indicating the end of the stream. In this implementation I chose to ignore both chunks. An alternative solution could be to replace `<EOS_TOKEN>` with `\n` Tests: manually tested that the new model work with both `llm.generate()` and `llm.stream()`. Tested with `temperature`, `p` and `stop` parameters.

mziru	9e3c1d4463	add HTMLHeaderTextSplitter (#11039 ) Description: Similar in concept to the `MarkdownHeaderTextSplitter`, the `HTMLHeaderTextSplitter` is a "structure-aware" chunker that splits text at the element level and adds metadata for each header "relevant" to any given chunk. It can return chunks element by element or combine elements with the same metadata, with the objectives of (a) keeping related text grouped (more or less) semantically and (b) preserving context-rich information encoded in document structures. It can be used with other text splitters as part of a chunking pipeline.

Predrag Gruevski	42d979efdd	Improve type hints and interface for SQL execution functionality. (#11353 ) The previous API of the `_execute()` function had a few rough edges that this PR addresses: - The `fetch` argument was type-hinted as being able to take any string, but any string other than `"all"` or `"one"` would `raise ValueError`. The new type hints explicitly declare that only those values are supported. - The return type was type-hinted as `Sequence` but using `fetch = "one"` would actually return a single result item. This was incorrectly suppressed using `# type: ignore`. We now always return a list. - Using `fetch = "one"` would return a single item if data was found, or an empty list if no data was found. This was confusing, and we now always return a list to simplify. - The return type was `Sequence[Any]` which was a bit difficult to use since it wasn't clear what one could do with the returned rows. I'm making the new type `Dict[str, Any]` that corresponds to the column names and their values in the query. I've updated the use of this method elsewhere in the file to match the new behavior.	12 months ago
