Predrag Gruevski	e2d6c41177	Upgrade langchain dependencies. (#11420 ) I was hoping this would pick up numpy 1.26, which is required to support the new Python 3.12 release, but it didn't. It seems that some transitive dependency requirement on numpy is preventing that, and the highest we can currently go is 1.24.x. But to find this out required a 15min `poetry lock`, so I figured we might as well upgrade the dependencies we can and hopefully make the next dependency upgrade a bit smaller.	9 months ago

It lives in `docs/extras` directory. If no one reviews your PR within a few days, please @-mention one of @baskaryan, @eyurtsev, @hwchase17. --> ## Description Currently SQLAlchemy >=1.4.0 is a hard requirement. 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. Current failure: ``` langchain==0.0.305 sqlalchemy==1.3.24 ``` ``` python python -i >>> from langchain.vectorstores import FAISS Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/__init__.py", line 58, in <module> from langchain.vectorstores.pgembedding import PGEmbedding File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/pgembedding.py", line 10, in <module> from sqlalchemy.orm import Session, declarative_base, relationship ImportError: cannot import name 'declarative_base' from 'sqlalchemy.orm' (/pay/src/zoolander/vendor3/lib/python3.8/site-packages/sqlalchemy/orm/__init__.py) ``` 2.

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	10 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.	10 months ago

Clément Sicard	1b48d6cb8c	`LlamaCppEmbeddings`: adds `verbose` parameter, similar to `llms.LlamaCpp` class (#11038 ) ## Description As of now, when instantiating and during inference, `LlamaCppEmbeddings` outputs (a lot of) verbose when controlled from Langchain binding - it is a bit annoying when computing the embeddings of long documents, for instance. This PR adds `verbose` for `LlamaCppEmbeddings` objects to be able not to print the verbose of the model to `stderr`. It is natively supported by `llama-cpp-python` and directly passed to the library – the PR is hence very small. The value of `verbose` is `True` by default, following the way it is defined in [`LlamaCpp` (`llamacpp.py` #L136-L137)](`c87e9fb2ce/libs/langchain/langchain/llms/llamacpp.py (L136-L137)`) ## Issue _No issue linked_ ## Dependencies _No additional dependency needed_ ## To see it in action ```python from langchain.embeddings import LlamaCppEmbeddings MODEL_PATH = "<path_to_gguf_file>" if __name__ == "__main__": llm_embeddings = LlamaCppEmbeddings( model_path=MODEL_PATH, n_gpu_layers=1, n_batch=512, n_ctx=2048, f16_kv=True, verbose=False, ) ``` Co-authored-by: Bagatur <baskaryan@gmail.com>	10 months ago

Michael Landis	a8db594012	fix: short-circuit black and mypy calls when no changes made (#11051 ) Both black and mypy expect a list of files or directories as input. As-is the Makefile computes a list files changed relative to the last commit; these are passed to black and mypy in the `format_diff` and `lint_diff` targets. This is done by way of the Makefile variable `PYTHON_FILES`. This is to save time by skipping running mypy and black over the whole source tree. When no changes have been made, this variable is empty, so the call to black (and mypy) lacks input files. The call exits with error causing the Makefile target to error out with: ```bash $ make format_diff poetry run black Usage: black [OPTIONS] SRC ... One of 'SRC' or 'code' is required. make: *** [format_diff] Error 1 ``` This is unexpected and undesirable, as the naive caller (that's me! 😄 ) will think something else is wrong. This commit smooths over this by short circuiting when `PYTHON_FILES` is empty.	10 months ago

This has also been tested to fix the chat_model implementation as well. Happy to answer any further questions or make changes where necessary to get things patched and up to PyPi ASAP, TY. - Issue: No issue opened at the moment, though will update when these roll in. - Dependencies: None --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	10 months ago
xiaoyu	b87cc8b31e	add 3 property types in metadata for notiondb loader (#8509 ) ### Description: NotionDB supports a number of common property types. I have found three common types that are not included in notiondb loader. When programs loaded them with notiondb, which will cause some metadata information not to be passed to langchain. Therefore, I added three common types: - date - created_time - last_edit_time. ### Issue: no ### Dependencies: No dependencies added :) ### Tag maintainer: @rlancemartin, @eyurtsev ### Twitter handle: @BJTUTC	10 months ago
Harrison Chase	258d67b0ac	Revert "improve the performance of base.py" (#11143 ) Reverts langchain-ai/langchain#8610 this is actually an oversight - this merges all dfs into one df. we DO NOT want to do this - the idea is we work and manipulate multiple dfs	10 months ago
Mohamad Zamini	9306394078	improve the performance of base.py (#8610 ) This removes the use of the intermediate df list and directly concatenates the dataframes if path is a list of strings. The pd.concat function combines the dataframes efficiently, making it faster and more memory-efficient compared to appending dataframes to a list. <!-- Thank you for contributing to LangChain!

Mincoolee	05b75f3f13	feat: add support for arxiv identifier in ArxivAPIWrapper() (#9318 ) - Description: this PR adds the support for arxiv identifier of the ArxivAPIWrapper. I modified the `run()` and `load()` functions in `arxiv.py`, using regex to recognize if the query is in the form of arxiv identifier (see [https://info.arxiv.org/help/find/index.html](https://info.arxiv.org/help/find/index.html)). If so, it will directly search the paper corresponding to the arxiv identifier. I also modified and added tests in `test_arxiv.py`. - Issue: #9047 - Dependencies: N/A - Tag maintainer: N/A --------- Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	10 months ago
