Jan Nissen	2e0ddd6fb8	core[minor]: support pydantic v2 models in PydanticOutputParser (#18811 ) As mentioned in #18322, the current PydanticOutputParser won't work for anyone trying to parse to pydantic v2 models. This PR adds a separate `PydanticV2OutputParser`, as well as a `langchain_core.pydantic_v2` namespace that will fail on import to any projects using pydantic<2. Happy to update the docs for output parsers if this is something we're interesting in adding. On a separate note, I also updated `check_pydantic.sh` to detect pydantic imports with leading whitespace and excluded the internal namespaces. That change can be separated into its own PR if needed. --------- Co-authored-by: Jan Nissen <jan23@gmail.com>	6 months ago

mwmajewsk	f7a1fd91b8	community: better support of pathlib paths in document loaders (#18396 ) So this arose from the https://github.com/langchain-ai/langchain/pull/18397 problem of document loaders not supporting `pathlib.Path`. This pull request provides more uniform support for Path as an argument. The core ideas for this upgrade: - if there is a local file path used as an argument, it should be supported as `pathlib.Path` - if there are some external calls that may or may not support Pathlib, the argument is immidiately converted to `str` - if there `self.file_path` is used in a way that it allows for it to stay pathlib without conversion, is is only converted for the metadata.

Yuki Watanabe	cfecbda48b	community[minor]: Allow passing `allow_dangerous_deserialization` when loading LLM chain (#18894 ) ### Issue Recently, the new `allow_dangerous_deserialization` flag was introduced for preventing unsafe model deserialization that relies on pickle without user's notice (#18696). Since then some LLMs like Databricks requires passing in this flag with true to instantiate the model. However, this breaks existing functionality to loading such LLMs within a chain using `load_chain` method, because the underlying loader function [load_llm_from_config](`f96dd57501/libs/langchain/langchain/chains/loading.py (L40)`) (and load_llm) ignores keyword arguments passed in. ### Solution This PR fixes this issue by propagating the `allow_dangerous_deserialization` argument to the class loader iff the LLM class has that field. --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	6 months ago

Shotaro Sano	55c624a694	infra: Resolve the endless dependency resolution during the build of `dev.Dockerfile` by copying `poetry.lock` (#19465 ) ## Description This PR proposes a modification to the `libs/langchain/dev.Dockerfile` configuration to copy the `libs/langchain/poetry.lock` into the working directory. The change aims to address the issue where the Poetry install command, the last command in the `dev.Dockerfile`, takes excessively long hours, and to ensure the reproducibility of the poetry environment in the devcontainer. ## Problem The `dev.Dockerfile`, prepared for development environments such as `.devcontainer`, encounters an unending dependency resolution when attempting the Poetry installation. ### Steps to Reproduce Execute the following build command: ```bash docker build -f libs/langchain/dev.Dockerfile . ``` ### Current Behavior The Docker build process gets stuck at the following step, which, in my experience, did not conclude even after an entire night: ``` => [langchain-dev-dependencies 4/6] COPY libs/community/ ../community/ 0.9s => [langchain-dev-dependencies 5/6] COPY libs/text-splitters/ ../text-splitters/ 0.0s => [langchain-dev-dependencies 6/6] RUN poetry install --no-interaction --no-ansi --with dev,test,docs 12.3s => => # Updating dependencies => => # Resolving dependencies... ``` ### Expected Behavior The Docker build completes in a realistic timeframe. By applying this PR, the build finishes within a few minutes. ### Analysis The complexity of LangChain's dependencies has reached a point where Poetry is required to resolve dependencies akin to threading a needle. Consequently, poetry install fails to complete in a practical timeframe. ## Solution The solution for dependency resolution is already recorded in `libs/langchain/poetry.lock`, so we can use it. When copying `project.toml` and `poetry.toml`, the `poetry.lock` located in the same directory should also be copied. ```diff # Copy only the dependency files for installation -COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml ./ +COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml libs/langchain/poetry.lock ./ ``` ## Note I am not intimately familiar with the historical context of the `dev.Dockerfile` and thus do not know why `poetry.lock` has not been copied until now. It might have been an oversight, or perhaps dependency resolution used to complete quickly even without the `poetry.lock` file in the past. However, if there are deliberate reasons why copying `poetry.lock` is not advisable, please just close this PR.	6 months ago

Clément Tamines	a6cbb755a7	community[patch]: fix semantic answer bug in AzureSearch vector store (#18938 ) - Description: The `semantic_hybrid_search_with_score_and_rerank` method of `AzureSearch` contains a hardcoded field name "metadata" for the document metadata in the Azure AI Search Index. Adding such a field is optional when creating an Azure AI Search Index, as other snippets from `AzureSearch` test for the existence of this field before trying to access it. Furthermore, the metadata field name shouldn't be hardcoded as "metadata" and use the `FIELDS_METADATA` variable that defines this field name instead. In the current implementation, any index without a metadata field named "metadata" will yield an error if a semantic answer is returned by the search in `semantic_hybrid_search_with_score_and_rerank`. - Issue: https://github.com/langchain-ai/langchain/issues/18731 - Prior fix to this bug: This bug was fixed in this PR https://github.com/langchain-ai/langchain/pull/15642 by adding a check for the existence of the metadata field named `FIELDS_METADATA` and retrieving a value for the key called "key" in that metadata if it exists. If the field named `FIELDS_METADATA` was not present, an empty string was returned. This fix was removed in this PR https://github.com/langchain-ai/langchain/pull/15659 (see `ed1ffca911`#). @lz-chen: could you confirm this wasn't intentional? - New fix to this bug: I believe there was an oversight in the logic of the fix from [#1564](https://github.com/langchain-ai/langchain/pull/15642) which I explain below. The `semantic_hybrid_search_with_score_and_rerank` method creates a dictionary `semantic_answers_dict` with semantic answers returned by the search as follows. `5c2f7e6b2b/libs/community/langchain_community/vectorstores/azuresearch.py (L574-L581)` The keys in this dictionary are the unique document ids in the index, if I understand the [documentation of semantic answers](https://learn.microsoft.com/en-us/azure/search/semantic-answers) in Azure AI Search correctly. When the method transforms a search result into a `Document` object, an "answer" key is added to the document's metadata. The value for this "answer" key should be the semantic answer returned by the search from this document, if such an answer is returned. The match between a `Document` object and the semantic answers returned by the search should be done through the unique document id, which is used as a key for the `semantic_answers_dict` dictionary. This id is defined in the search result's field named `FIELDS_ID`. I added a check to avoid any error in case no field named `FIELDS_ID` exists in a search result (which shouldn't happen in theory). A benefit of this approach is that this fix should work whether or not the Azure AI Search Index contains a metadata field. @levalencia could you confirm my analysis and test the fix? @raunakshrivastava7 do you agree with the fix?

Marlene	f1313339ac	community[patch]: Fixing incorrect base URLs for Azure Cognitive Search Retriever (#19352 ) This PR adds code to make sure that the correct base URL is being created for the Azure Cognitive Search retriever. At the moment an incorrect base URL is being generated. I think this is happening because the original code was based on a depreciated API version. No dependencies need to be added. I've also added more context to the test doc strings. I should also note that ACS is now Azure AI Search. I will open a separate PR to make these changes as that would be a breaking change and should potentially be discussed. Twitter: @marlene_zw - No new tests added, however the current ACS retriever tests are now passing when I run them. - Code was linted.

Chris Papademetrious	305d74c67a	core: implement a batch_size parameter for CacheBackedEmbeddings (#18070 ) Description: Currently, `CacheBackedEmbeddings` computes vectors for all uncached documents before updating the store. This pull request updates the embedding computation loop to compute embeddings in batches, updating the store after each batch. I noticed this when I tried `CacheBackedEmbeddings` on our 30k document set and the cache directory hadn't appeared on disk after 30 minutes. The motivation is to minimize compute/data loss when problems occur: * If there is a transient embedding failure (e.g. a network outage at the embedding endpoint triggers an exception), at least the completed vectors are written to the store instead of being discarded. * If there is an issue with the store (e.g. no write permissions), the condition is detected early without computing (and discarding!) all the vectors. Issue: Implements enhancement #18026. Testing: I was unable to run unit tests; details in [this post](https://github.com/langchain-ai/langchain/discussions/15019#discussioncomment-8576684). --------- Signed-off-by: chrispy <chrispy@synopsys.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	6 months ago

Description : Updates the _rm_titles function to check the presence of the 'type' key as well before removing the 'title' key. As the title key that we wish to omit always has a type key along with it. Potential gap if there is a function defined which has both title and key as argument names, in which case this would fail.

Shotaro Sano	ca9c8c58ea	text-splitters, infra: fix `libs/langchain/dev.Dockerfile` so that the `text-splitter` directory is copied before poetry installation (#19214 ) ## Description This PR modifies the settings in `libs/langchain/dev.Dockerfile` to ensure that the `text-splitters` directory is copied before the poetry installation process begins. Without this modification, the `docker build` command fails for `dev.Dockerfile`, preventing the setup of some development environments, including `.devcontainer`. ## Bug Details ### Repro Run the following command: ```bash docker build -f libs/langchain/dev.Dockerfile . ``` ### Current Behavior The docker build command fails, raising the following error: ``` ... => [langchain-dev-dependencies 4/5] COPY libs/community/ ../community/ 0.4s => ERROR [langchain-dev-dependencies 5/5] RUN poetry install --no-interaction --no-ansi --with dev,test,docs 1.1s ------ > [langchain-dev-dependencies 5/5] RUN poetry install --no-interaction --no-ansi --with dev,test,docs: #13 0.970 #13 0.970 Directory ../text-splitters does not exist ------ executor failed running [/bin/sh -c poetry install --no-interaction --no-ansi --with dev,test,docs]: exit code: 1 ``` ### Expected Behavior The `docker build` command successfully completes without the poetry error. ### Analysis The error occurs because the `text-splitters` directory is not copied into the build environment, unlike the other packages under the `libs` directory. I suspect that the `COPY` setting was overlooked since `text-splitters` was separated in a recent PR. ## Fix Add the following lines to the `libs/langchain/dev.Dockerfile`: ```dockerfile # Copy the text-splitters library for installation COPY libs/text-splitters/ ../text-splitters/ ```	6 months ago

William FH	780337488e	[Enhancement] Add support for directly providing a run_id (#18990 ) The root run id (~trace id's) is useful for assigning feedback, but the current recommended approach is to use callbacks to retrieve it, which has some drawbacks: 1. Doesn't work for streaming until after the first event 2. Doesn't let you call other endpoints with the same trace ID in parallel (since you have to wait until the call is completed/started to use This PR lets you provide = "run_id" in the runnable config. Couple considerations: 1. For batch calls, we split the trace up into separate trees (to permit better rendering). We keep the provided run ID for the first one and generate a unique one for other elements of the batch. 2. For nested calls, the provided ID is ONLY used on the top root/trace. ### Example Usage ``` chain.invoke("foo", {"run_id": uuid.uuid4()}) ```	6 months ago

Ishani Vyas	2b0cbd65ba	community[patch]: Add Passio Nutrition AI Food Search Tool to Community Package (#18278 ) ## Add Passio Nutrition AI Food Search Tool to Community Package ### Description We propose adding a new tool to the `community` package, enabling integration with Passio Nutrition AI for food search functionality. This tool will provide a simple interface for retrieving nutrition facts through the Passio Nutrition AI API, simplifying user access to nutrition data based on food search queries. ### Implementation Details - Class Structure: Implement `NutritionAI`, extending `BaseTool`. It includes an `_run` method that accepts a query string and, optionally, a `CallbackManagerForToolRun`. - API Integration: Use `NutritionAIAPI` for the API wrapper, encapsulating all interactions with the Passio Nutrition AI and providing a clean API interface. - Error Handling: Implement comprehensive error handling for API request failures. ### Expected Outcome - User Benefits: Enable easy querying of nutrition facts from Passio Nutrition AI, enhancing the utility of the `langchain_community` package for nutrition-related projects. - Functionality: Provide a straightforward method for integrating nutrition information retrieval into users' applications. ### Dependencies - `langchain_core` for base tooling support - `pydantic` for data validation and settings management - Consider `requests` or another HTTP client library if not covered by `NutritionAIAPI`. ### Tests and Documentation - Unit Tests: Include tests that mock network interactions to ensure tool reliability without external API dependency. - Documentation: Create an example notebook in `docs/docs/integrations/tools/passio_nutrition_ai.ipynb` showing usage, setup, and example queries. ### Contribution Guidelines Compliance - Adhere to the project's linting and formatting standards (`make format`, `make lint`, `make test`). - Ensure compliance with LangChain's contribution guidelines, particularly around dependency management and package modifications. ### Additional Notes - Aim for the tool to be a lightweight, focused addition, not introducing significant new dependencies or complexity. - Potential future enhancements could include caching for common queries to improve performance. ### Twitter Handle - Here is our Passio AI [twitter handle](https://twitter.com/@passio_ai) where we announce our products.

Jan Nissen	b8922480ed	core[patch]: improve PydanticOutputParser typing (#18740 ) This PR adds generic typing to `PydanticOutputParser` so we get a typed output from `.parse` instead of `Any`.

Ian	390ef6abe3	community[minor]: Add Initial Support for TiDB Vector Store (#15796 ) This pull request introduces initial support for the TiDB vector store. The current version is basic, laying the foundation for the vector store integration.

Piyush Jain	2b234a4d96	Support for claude v3 models. (#18630 ) Fixes #18513. ## Description This PR attempts to fix the support for Anthropic Claude v3 models in BedrockChat LLM. The changes here has updated the payload to use the `messages` format instead of the formatted text prompt for all models; `messages` API is backwards compatible with all models in Anthropic, so this should not break the experience for any models. ## Notes The PR in the current form does not support the v3 models for the non-chat Bedrock LLM. This means, that with these changes, users won't be able to able to use the v3 models with the Bedrock LLM. I can open a separate PR to tackle this use-case, the intent here was to get this out quickly, so users can start using and test the chat LLM. The Bedrock LLM classes have also grown complex with a lot of conditions to support various providers and models, and is ripe for a refactor to make future changes more palatable. This refactor is likely to take longer, and requires more thorough testing from the community.
