You need three packages: ChromaDotNet.Local starts Chroma on your machine, with the data in a folder you choose. It runs the native Chroma executable, written in Rust, which comes inside the package: no Docker, no Python. ChromaDotNet.Embeddings computes the same embeddings as the Python client (all-MiniLM-L6-v2): you pass the texts and it creates the vectors. A collection created from Python opens from...
