activation_store

Utility library to persistently store transformer activations on disk.

These activations can be quite large (layers x batch x sequence x hidden_size), so generating them to disk helps avoid out of memory errors.

Install using

pip install git+https://github.com/wassname/activation_store.git

Development

git clone https//github.com/wassname/activation_store.git
uv sync

see examples in nbs folder.

TODO:

• test compression: it's not worth the complexity
• add examples
• generate and collect activations
  • A manual loop of forwards/generate, reusing kv_cache, and appending model outputs along the token dim. saving outputs too
