刘方瑞	890ed775a3	Resolve: VectorSearch enabled SQLChain? (#10177 ) Squashed from #7454 with updated features We have separated the `SQLDatabseChain` from `VectorSQLDatabseChain` and put everything into `experimental/`. Below is the original PR message from #7454. ------- We have been working on features to fill up the gap among SQL, vector search and LLM applications. Some inspiring works like self-query retrievers for VectorStores (for example [Weaviate](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/weaviate_self_query.html) and [others](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query.html)) really turn those vector search databases into a powerful knowledge base! 🚀🚀 We are thinking if we can merge all in one, like SQL and vector search and LLMChains, making this SQL vector database memory as the only source of your data. Here are some benefits we can think of for now, maybe you have more 👀: With ALL data you have: since you store all your pasta in the database, you don't need to worry about the foreign keys or links between names from other data source. Flexible data structure: Even if you have changed your schema, for example added a table, the LLM will know how to JOIN those tables and use those as filters. SQL compatibility: We found that vector databases that supports SQL in the marketplace have similar interfaces, which means you can change your backend with no pain, just change the name of the distance function in your DB solution and you are ready to go! ### Issue resolved: - [Feature Proposal: VectorSearch enabled SQLChain?](https://github.com/hwchase17/langchain/issues/5122) ### Change made in this PR: - An improved schema handling that ignore `types.NullType` columns - A SQL output Parser interface in `SQLDatabaseChain` to enable Vector SQL capability and further more - A Retriever based on `SQLDatabaseChain` to retrieve data from the database for RetrievalQAChains and many others - Allow `SQLDatabaseChain` to retrieve data in python native format - Includes PR #6737 - Vector SQL Output Parser for `SQLDatabaseChain` and `SQLDatabaseChainRetriever` - Prompts that can implement text to VectorSQL - Corresponding unit-tests and notebook ### Twitter handle: - @MyScaleDB ### Tag Maintainer: Prompts / General: @hwchase17, @baskaryan DataLoaders / VectorStores / Retrievers: @rlancemartin, @eyurtsev ### Dependencies: No dependency added	1 year ago

cccs-eric	b64a443f72	Fix SQL search_path for Trino query engine (#10248 ) This PR replaces the generic `SET search_path TO` statement by `USE` for the Trino dialect since Trino does not support `SET search_path`. Official Trino documentation can be found [here](https://trino.io/docs/current/sql/use.html).

Predrag Gruevski	ccb9e3ee2d	Install dev, lint, test, typing extra deps for linting steps. (#10249 ) `mypy` cannot type-check code that relies on dependencies that aren't installed. Eventually we'll probably want to install as many optional dependencies as possible. However, the full "extended deps" setup for langchain creates a 3GB cache file and takes a while to unpack and install. We'll probably want something a bit more targeted. This is a first step toward something better.	1 year ago
Predrag Gruevski	82d5d4d0ae	Deny creating files as a result of test runs. (#10253 ) A test file was accidentally dropping a `results.json` file in the current working directory as a result of running `make test`. This is undesirable, since we don't want to risk accidentally adding stray files into the repo if we run tests locally and then do `git add .` without inspecting the file list very closely.	1 year ago

ElReyZero	5dbae94e04	OpenAIEmbeddings: Add optional an optional parameter to skip empty embeddings (#10196 ) ## Description ### Issue This pull request addresses a lingering issue identified in PR #7070. In that previous pull request, an attempt was made to address the problem of empty embeddings when using the `OpenAIEmbeddings` class. While PR #7070 introduced a mechanism to retry requests for embeddings, it didn't fully resolve the issue as empty embeddings still occasionally persisted. ### Problem In certain specific use cases, empty embeddings can be encountered when requesting data from the OpenAI API. In some cases, these empty embeddings can be skipped or removed without affecting the functionality of the application. However, they might not always be resolved through retries, and their presence can adversely affect the functionality of applications relying on the `OpenAIEmbeddings` class. ### Solution To provide a more robust solution for handling empty embeddings, we propose the introduction of an optional parameter, `skip_empty`, in the `OpenAIEmbeddings` class. When set to `True`, this parameter will enable the behavior of automatically skipping empty embeddings, ensuring that problematic empty embeddings do not disrupt the processing flow. The developer will be able to optionally toggle this behavior if needed without disrupting the application flow. ## Changes Made - Added an optional parameter, `skip_empty`, to the `OpenAIEmbeddings` class. - When `skip_empty` is set to `True`, empty embeddings are automatically skipped without causing errors or disruptions. ### Example Usage ```python from openai.embeddings import OpenAIEmbeddings # Initialize the OpenAIEmbeddings class with skip_empty=True embeddings = OpenAIEmbeddings(api_key="your_api_key", skip_empty=True) # Request embeddings, empty embeddings are automatically skipped. docs is a variable containing the already splitted text. results = embeddings.embed_documents(docs) # Process results without interruption from empty embeddings ```	1 year ago

Cameron Hutchison	7d8bb78e5c	Extraction Chain - Custom Prompt (#9828 ) # Description This change allows you to customize the prompt used in `create_extraction_chain` as well as `create_extraction_chain_pydantic`. It also adds the `verbose` argument to `create_extraction_chain_pydantic` - because `create_extraction_chain` had it already and `create_extraction_chain_pydantic` did not. # Issue N/A # Dependencies N/A # Twitter https://twitter.com/CamAHutchison	1 year ago

Viktor Zhemchuzhnikov	507e46844e	Extend SQLChatMessageHistory (#9849 ) ### Description There is a really nice class for saving chat messages into a database - SQLChatMessageHistory. It leverages SqlAlchemy to be compatible with any supported database (in contrast with PostgresChatMessageHistory, which is basically the same but is limited to Postgres). However, the class is not really customizable in terms of what you can store. I can imagine a lot of use cases, when one will need to save a message date, along with some additional metadata. To solve this, I propose to extract the converting logic from BaseMessage to SQLAlchemy model (and vice versa) into a separate class - message converter. So instead of rewriting the whole SQLChatMessageHistory class, a user will only need to write a custom model and a simple mapping class, and pass its instance as a parameter. I also noticed that there is no documentation on this class, so I added that too, with an example of custom message converter. ### Issue N/A ### Dependencies N/A ### Tag maintainer Not yet ### Twitter handle N/A	1 year ago
