Yuki Watanabe	3981d736df	databricks: Add partner package directory and ChatDatabricks implementation (#25430 ) ### Summary Create `langchain-databricks` as a new partner packages. This PR does not migrate all existing Databricks integration, but the package will eventually contain: * `ChatDatabricks` (implemented in this PR) * `DatabricksVectorSearch` * `DatabricksEmbeddings` * ~`UCFunctionToolkit`~ (will be done after UC SDK work which drastically simplify implementation) Also, this PR does not add integration tests yet. This will be added once the Databricks test workspace is ready. Tagging @efriis as POC ### Tracker [✍️] Create a package and imgrate ChatDatabricks [ ] Migrate DatabricksVectorSearch, DatabricksEmbeddings, and their docs ~[ ] Migrate UCFunctionToolkit and its doc~ [ ] Add provider document and update README.md [ ] Add integration tests and set up secrets (after moved to an external package) [ ] Add deprecation note to the community implementations. --------- Signed-off-by: B-Step62 <yuki.watanabe@databricks.com> Co-authored-by: Erick Friis <erick@langchain.dev>	4 weeks ago

Bob Merkus	8e3e532e7d	docs: ollama doc update (toolcalling, install, notebook examples) (#25549 ) The new `langchain-ollama` package seems pretty well implemented, but I noticed the docs were still outdated so I decided to fix em up a bit. - Llama3.1 was release on 23rd of July; https://ai.meta.com/blog/meta-llama-3-1/ - Ollama supports tool calling since 25th of July; https://ollama.com/blog/tool-support - LangChain Ollama partner package was released 1st of august; https://pypi.org/project/langchain-ollama/ Problem: Docs note langchain-community instead of langchain-ollama Solution: Update docs to https://python.langchain.com/v0.2/docs/integrations/chat/ollama/ Problem: OllamaFunctions is deprecated, as noted on [Integrations](https://python.langchain.com/v0.2/docs/integrations/chat/ollama_functions/): This was an experimental wrapper that attempts to bolt-on tool calling support to models that do not natively support it. The [primary Ollama integration](https://python.langchain.com/v0.2/docs/integrations/chat/ollama/) now supports tool calling, and should be used instead. Solution: Delete old notebook from repo, update the existing one with @tool decorator + pydantic examples to the notebook Problem: Llama3.1 was released while llama3-groq-tool-call fine-tune Is noted in notebooks. Solution: update docs + notebooks to llama3.1 (which has improved tool calling support) Problem: Install instructions are incomplete, there is no information to download a model and/or run the Ollama server Solution: Add simple instructions to start the ollama service and pull model (for toolcalling) --------- Co-authored-by: Chester Curme <chester.curme@gmail.com>	1 month ago

ccurme	c5bf114c0f	together, standard-tests: specify tool_choice in standard tests (#25548 ) Here we allow standard tests to specify a value for `tool_choice` via a `tool_choice_value` property, which defaults to None. Chat models [available in Together](https://docs.together.ai/docs/chat-models) have issues passing standard tool calling tests: - llama 3.1 models currently [appear to rely on user-side parsing](https://docs.together.ai/docs/llama-3-function-calling) in Together; - Mixtral-8x7B and Mistral-7B (currently tested) consistently do not call tools in some tests. Specifying tool_choice also lets us remove an existing `xfail` and use a smaller model in Groq tests.	1 month ago

Mohammad Mohtashim	75c3c81b8c	[Community]: Fix - Open AI Whisper `client.audio.transcriptions` returning Text Object which raises error (#25271 ) - Description: The following [line](`fd546196ef/libs/community/langchain_community/document_loaders/parsers/audio.py (L117)`) in `OpenAIWhisperParser` returns a text object for some odd reason despite the official documentation saying it should return `Transcript` Instance which should have the text attribute. But for the example given in the issue and even when I tried running on my own, I was directly getting the text. The small PR accounts for that. - Issue: : #25218 I was able to replicate the error even without the GenericLoader as shown below and the issue was with `OpenAIWhisperParser` ```python parser = OpenAIWhisperParser(api_key="sk-fxxxxxxxxx", response_format="srt", temperature=0) list(parser.lazy_parse(Blob.from_path('path_to_file.m4a'))) ```	1 month ago
