Anton Troynikov	d2ef5d6167	Default Chroma collection name (#1198) ... For persistence, it's convenient to have a default collection name which gets used everywhere.	1 year ago
Jeff Huber	34cba2da32	Fix typo in integration with Chroma (#1070) ... We introduced a breaking change but missed this call. This PR fixes `langchain` to work with upstream `chroma`.	1 year ago
Anton Troynikov	d43d430d86	Chroma persistence (#1028) ... This PR adds persistence to the Chroma vector store. Users can supply a `persist_directory` with any of the `Chroma` creation methods. If supplied, the store will be automatically persisted at that directory. If a user creates a new `Chroma` instance with the same persistence directory, it will get loaded up automatically. If they use `from_texts` or `from_documents` in this way, the documents will be loaded into the existing store. There is the chance of some funky behavior if the user passes a different embedding function from the one used to create the collection - we will make this easier in future updates. For now, we log a warning.	1 year ago

Anton Troynikov	78abd277ff	Chroma in LangChain (#1010) ... Chroma is a simple to use, open-source, zero-config, zero setup vectorstore. Simply `pip install chromadb`, and you're good to go. Out-of-the-box Chroma is suitable for most LangChain workloads, but is highly flexible. I tested to 1M embs on my M1 mac, with out issues and reasonably fast query times. Look out for future releases as we integrate more Chroma features with LangChain!	1 year ago
