Charlie Holtz	1cbab0ebda	community: update Replicate to work with official models (#20633 ) Description: you don't need to pass a version for Replicate official models. That was broken on LangChain until now! You can now run: ``` llm = Replicate( model="meta/meta-llama-3-8b-instruct", model_kwargs={"temperature": 0.75, "max_length": 500, "top_p": 1}, ) prompt = """ User: Answer the following yes/no question by reasoning step by step. Can a dog drive a car?

Congyu	dd5139e304	community[patch]: truncate zhipuai `temperature` and `top_p` parameters to [0.01, 0.99] (#20261 ) ZhipuAI API only accepts `temperature` parameter between `(0, 1)` open interval, and if `0` is passed, it responds with status code `400`. However, 0 and 1 is often accepted by other APIs, for example, OpenAI allows `[0, 2]` for temperature closed range. This PR truncates temperature parameter passed to `[0.01, 0.99]` to improve the compatibility between langchain's ecosystem's and ZhipuAI (e.g., ragas `evaluate` often generates temperature 0, which results in a lot of 400 invalid responses). The PR also truncates `top_p` parameter since it has the same restriction. Reference: [glm-4 doc](https://open.bigmodel.cn/dev/api#glm-4) (which unfortunately is in Chinese though). --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	6 months ago

hulitaitai	7d0a008744	community[minor]: Add audio-parser "faster-whisper" in audio.py (#20012 ) faster-whisper is a reimplementation of OpenAI's Whisper model using CTranslate2, which is up to 4 times faster than enai/whisper for the same accuracy while using less memory. The efficiency can be further improved with 8-bit quantization on both CPU and GPU. It can automatically detect the following 14 languages and transcribe the text into their respective languages: en, zh, fr, de, ja, ko, ru, es, th, it, pt, vi, ar, tr.

ccurme	c897264b9b	community: (milvus) check for num_shards (#20603 ) @rgupta2508 I believe this change is necessary following https://github.com/langchain-ai/langchain/pull/20318 because of how Milvus handles defaults: `59bf5e811a/pymilvus/client/prepare.py (L82-L85)` ```python num_shards = kwargs[next(iter(same_key))] if not isinstance(num_shards, int): msg = f"invalid num_shards type, got {type(num_shards)}, expected int" raise ParamError(message=msg) req.shards_num = num_shards ``` this way lets Milvus control the default value (instead of maintaining a separate default in Langchain). Let me know if I've got this wrong or you feel it's unnecessary. Thanks.	6 months ago

pjb157	479be3cc91	community[minor]: Unify Titan Takeoff Integrations and Adding Embedding Support (#18775 ) Community: Unify Titan Takeoff Integrations and Adding Embedding Support Description: Titan Takeoff no longer reflects this either of the integrations in the community folder. The two integrations (TitanTakeoffPro and TitanTakeoff) where causing confusion with clients, so have moved code into one place and created an alias for backwards compatibility. Added Takeoff Client python package to do the bulk of the work with the requests, this is because this package is actively updated with new versions of Takeoff. So this integration will be far more robust and will not degrade as badly over time. Issue: Fixes bugs in the old Titan integrations and unified the code with added unit test converge to avoid future problems. Dependencies: Added optional dependency takeoff-client, all imports still work without dependency including the Titan Takeoff classes but just will fail on initialisation if not pip installed takeoff-client Twitter @MeryemArik9 Thanks all :) --------- Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	6 months ago

Description: vlite is a simple and blazing fast vector database(vdb) made with numpy. It abstracts a lot of the functionality around using a vdb in the retrieval augmented generation(RAG) pipeline such as embeddings generation, chunking, and file processing while still giving developers the functionality to change how they're made/stored.

Hyeongchan Kim	7824291252	community[patch]: Fix not to cast to str type when `file_path` is None (#20057 ) From `langchain_community 0.0.30`, there's a bug that cannot send a file-like object via `file` parameter instead of `file path` due to casting the `file_path` to str type even if `file_path` is None. which means that when I call the `partition_via_api()`, exactly one of `filename` and `file` must be specified by the following error message. however, from `langchain_community 0.0.30`, `file_path` is casted into `str` type even `file_path` is None in `get_elements_from_api()` and got an error at `exactly_one(filename=filename, file=file)`. here's an error message ``` ---> 51 exactly_one(filename=filename, file=file) 53 if metadata_filename and file_filename: 54 raise ValueError( 55 "Only one of metadata_filename and file_filename is specified. " 56 "metadata_filename is preferred. file_filename is marked for deprecation.", 57 ) File /opt/homebrew/lib/python3.11/site-packages/unstructured/partition/common.py:441, in exactly_one(**kwargs) 439 else: 440 message = f"{names[0]} must be specified." --> 441 raise ValueError(message) ValueError: Exactly one of filename and file must be specified. ``` So, I simply made a change that casting to str type when `file_path` is not None. I use `UnstructuredAPIFileLoader` like below. ``` from langchain_community.document_loaders.unstructured import UnstructuredAPIFileLoader documents: list = UnstructuredAPIFileLoader( file_path=None, file=file, # file-like object, io.BytesIO type mode='elements', url='http://127.0.0.1:8000/general/v0/general', content_type='application/pdf', metadata_filename='asdf.pdf', ).load_and_split() ```	6 months ago
