We install some stuff on Nix (as much as we can) and the rest with `uv pip`.

That works well. Which means it installs. But the `venv`, which is in `.venv`, also has a python runtime there, and as we're using the nix store python runtime, it won't see the venv packages. So you gotta do `source .venv/bin/activate` which is pretty weird but it does work.

Apparently transformers need the with torch.no_grad(): thing all the time but sentence transformers don't. at all




## DIM creating the DB table is retarded damn you chatgpt
>>  he says
TL;DR

DIM = number of floats per embedding vector (fixed by the model).

sqlite-vec needs it at table creation.

You don’t restart the DB every run — you just make sure new embeddings match the stored DIM.

Best practice: store model+dim in a meta table so you don’t accidentally mix dimensions.
