Beschreibung

Issue you'd like to raise.

I am trying to delete a single document from Chroma db using the following code:

chroma_db = Chroma(persist_directory = embeddings_save_path, embedding_function = OpenAIEmbeddings(model = os.getenv("EMBEDDING_MODEL_NAME"), chunk_size = 1, max_retries = 5) )

chroma_db._collection.delete(ids = list_of_ids) chroma_db.persist()

However, the document is not actually being deleted. After loading/re-loading the chroma db from local, it is still showing the document in it.

I have tried the following things to fix the issue:

I have made sure that the list of ids is correct. I have tried deleting the document multiple times. I have tried restarting the Chroma db server. None of these things have worked.

I am not sure why the document is not being deleted. I would appreciate any help in resolving this issue.

Thanks, Anant Patankar

Research-Richtung
Investigate the Chroma class in langchain's vectorstores implementation, specifically the ` collection.delete` and `persist` methods. Check if the deletion is actually persisted to disk or if there is a caching issue. Look at the ChromaDB documentation for the correct delete workflow. Examine the GitHub issue comments for any attempted solutions or reproduction steps.
