+# cache_transformer_activations
+
+Utility library to collect transformer activations **on disk**.
+
+These activations can be quite large (layers x batch x sequence x hidden_size), so it's nice to store it on disk and avoid and out of memory error.
+
+Install using `pip install git+https://github.com/wassname/cache_transformer_activations.git`.
+
+## Development
+```
+git clone https//github.com/wassname/cache_transformer_activations.git
+uv sync
+```
+
+see exampes in `nbs` folder.
