M Waleed Kadous	5124c1e0d9	Add aviary support (#5661 ) Aviary is an open source toolkit for evaluating and deploying open source LLMs. You can find out more about it on [http://github.com/ray-project/aviary). You can try it out at [http://aviary.anyscale.com](aviary.anyscale.com). This code adds support for Aviary in LangChain. To minimize dependencies, it connects directly to the HTTP endpoint. The current implementation is not accelerated and uses the default implementation of `predict` and `generate`. It includes a test and a simple example. @hwchase17 and @agola11 could you have a look at this? --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

Hao Chen	a4c9053d40	Integrate Clickhouse as Vector Store (#5650 ) <!-- Thank you for contributing to LangChain! Your PR will appear in our release under the title you set. Please make sure it highlights your valuable contribution. Replace this with a description of the change, the issue it fixes (if applicable), and relevant context. List any dependencies required for this change. After you're done, someone will review your PR. They may suggest improvements. If no one reviews your PR within a few days, feel free to @-mention the same people again, as notifications can get lost. Finally, we'd love to show appreciation for your contribution - if you'd like us to shout you out on Twitter, please also include your handle! --> #### Description This PR is mainly to integrate open source version of ClickHouse as Vector Store as it is easy for both local development and adoption of LangChain for enterprises who already have large scale clickhouse deployment. ClickHouse is a open source real-time OLAP database with full SQL support and a wide range of functions to assist users in writing analytical queries. Some of these functions and data structures perform distance operations between vectors, [enabling ClickHouse to be used as a vector database](https://clickhouse.com/blog/vector-search-clickhouse-p1). Recently added ClickHouse capabilities like [Approximate Nearest Neighbour (ANN) indices](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/annindexes) support faster approximate matching of vectors and provide a promising development aimed to further enhance the vector matching capabilities of ClickHouse. In LangChain, some ClickHouse based commercial variant vector stores like [Chroma](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/chroma.py) and [MyScale](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/myscale.py), etc are already integrated, but for some enterprises with large scale Clickhouse clusters deployment, it will be more straightforward to upgrade existing clickhouse infra instead of moving to another similar vector store solution, so we believe it's a valid requirement to integrate open source version of ClickHouse as vector store. As `clickhouse-connect` is already included by other integrations, this PR won't include any new dependencies. #### Before submitting <!-- If you're adding a new integration, please include: 1.

Tomaz Bratanic	a0ea6f6b6b	Cypher search: Check if generated Cypher is provided in backticks (#5541 ) # Check if generated Cypher code is wrapped in backticks Some LLMs like the VertexAI like to explain how they generated the Cypher statement and wrap the actual code in three backticks: ![Screenshot from 2023-06-01 08-08-23](https://github.com/hwchase17/langchain/assets/19948365/1d8eecb3-d26c-4882-8f5b-6a9bc7e93690) I have observed a similar pattern with OpenAI chat models in a conversational settings, where multiple user and assistant message are provided to the LLM to generate Cypher statements, where then the LLM wants to maybe apologize for previous steps or explain its thoughts. Interestingly, both OpenAI and VertexAI wrap the code in three backticks if they are doing any explaining or apologizing. Checking if the generated cypher is wrapped in backticks seems like a low-hanging fruit to expand the cypher search to other LLMs and conversational settings.	1 year ago

Nathan Azrak	26ec845921	Raise an exception in MKRL and Chat Output Parsers if parsing text which contains both an action and a final answer (#5609 ) Raises exception if OutputParsers receive a response with both a valid action and a final answer Currently, if an OutputParser receives a response which includes both an action and a final answer, they return a FinalAnswer object. This allows the parser to accept responses which propose an action and hallucinate an answer without the action being parsed or taken by the agent. This PR changes the logic to: 1. store a variable checking whether a response contains the `FINAL_ANSWER_ACTION` (this is the easier condition to check). 2. store a variable checking whether the response contains a valid action 3. if both are present, raise a new exception stating that both are present 4. if an action is present, return an AgentAction 5. if an answer is present, return an AgentAnswer 6. if neither is present, raise the relevant exception based around the action format (these have been kept consistent with the prior exception messages) Disclaimer: * Existing mock data included strings which did include an action and an answer. This might indicate that prioritising returning AgentAnswer was always correct, and I am patching out desired behaviour? @hwchase17 to advice. Curious if there are allowed cases where this is not hallucinating, and we do want the LLM to output an action which isn't taken. * I have not passed `send_to_llm` through this new exception Fixes #5601 ## Who can review?

This is a two-fold problem, where the resulting embedding for the updated document is incorrect (it's only an embedding of the first character in the new page_content) and it calls the embedding function for every character in the new page_content string, using many tokens in the process.

It is important, as there are some limits for the maximum size of the request payload, and without batching implemented in Langchain, users need to implement it on their own. This PR exposes a new optional `batch_size` parameter, so all the documents/texts are loaded in batches of the expected size (64, by default). The integration tests of Qdrant are extended to cover two cases: 1. Documents are sent in separate batches. 2. All the documents are sent in a single request.	1 year ago

Martin Holecek	44b48d9518	Fix update_document function, add test and documentation. (#5359 ) # Fix for `update_document` Function in Chroma ## Summary This pull request addresses an issue with the `update_document` function in the Chroma class, as described in [#5031](https://github.com/hwchase17/langchain/issues/5031#issuecomment-1562577947). The issue was identified as an `AttributeError` raised when calling `update_document` due to a missing corresponding method in the `Collection` object. This fix refactors the `update_document` method in `Chroma` to correctly interact with the `Collection` object. ## Changes 1. Fixed the `update_document` method in the `Chroma` class to correctly call methods on the `Collection` object. 2. Added the corresponding test `test_chroma_update_document` in `tests/integration_tests/vectorstores/test_chroma.py` to reflect the updated method call. 3. Added an example and explanation of how to use the `update_document` function in the Jupyter notebook tutorial for Chroma. ## Test Plan All existing tests pass after this change. In addition, the `test_chroma_update_document` test case now correctly checks the functionality of `update_document`, ensuring that the function works as expected and updates the content of documents correctly. ## Reviewers @dev2049 This fix will ensure that users are able to use the `update_document` function as expected, without encountering the previous `AttributeError`. This will enhance the usability and reliability of the Chroma class for all users. Thank you for considering this pull request. I look forward to your feedback and suggestions.	1 year ago

os1ma	1366d070fc	Add path validation to DirectoryLoader (#5327 ) # Add path validation to DirectoryLoader This PR introduces a minor adjustment to the DirectoryLoader by adding validation for the path argument. Previously, if the provided path didn't exist or wasn't a directory, DirectoryLoader would return an empty document list due to the behavior of the `glob` method. This could potentially cause confusion for users, as they might expect a file-loading error instead. So, I've added two validations to the load method of the DirectoryLoader: - Raise a FileNotFoundError if the provided path does not exist - Raise a ValueError if the provided path is not a directory Due to the relatively small scope of these changes, a new issue was not created. ## Before submitting <!-- If you're adding a new integration, please include: 1. a test for the integration - favor unit tests that does not rely on network access. 2. an example notebook showing its use See contribution guidelines for more information on how to write tests, lint etc: https://github.com/hwchase17/langchain/blob/master/.github/CONTRIBUTING.md --> ## Who can review?
