Description

🚀 Feature

We should be able to: (1) Understand which op is used for FW/BW (via additional logging enabled with an env variable?) (2) Possibly disable some ops entirely with env variable (like CUDA_VISIBLE_DEVICES but something like XFORMERS_MEMEFF_FW_OPERATORS=...)

Contributor guide

Research direction
Investigate how to add environment variable controls for memory efficient operators in xformers, specifically logging which op is used for forward/backward and disabling certain ops.
