Proposed fix: [Chroma] ValueError "An embedding function already exists in the collection configuration, and a new one is provided ... Embedding function conflict: new: X vs persisted: Y"
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Open the collection without an embedding_function (use the persisted one) or with the same one; for a new model create a new collection and re-embed; if intentional, compute embeddings yourself and pass them explicitly.
Option: Reuse the persisted EF or create a new collection [evidence: official_recommended_action]
Applies when: Changing embedding models
Steps:
1. client.get_collection(name) # no embedding_function
2. or create name_v2 with the new EF and re-ingest
Expected: Collection opens consistently
