well technically yes, but since it's in Rust once you have your embeddings, with some tweakings you could just store them and query them offline via ffi or wasm in an app for example. Also I am not a huge fan of maintaining python projects they often don't run after a while if I didn't properly maintain a virtual env etc never had this issue with Rust projects.

Yes, it's a well solved problem and much easier to do in Python. The author just wanted to do it in Rust, that's all.

sure, my point was more that it uses pytorch -> also lots of c++ :-)
