Description

I have implemented AMP for my model, it appears to be working, but there has been no decrease in VRAM usage for my model. I have tried optimizations "O1" and "O2".

Research direction

Start by collecting the missing model, environment, and AMP configuration details; the report only mentions AMP with optimizations O1 and O2. Compare VRAM usage under those configurations and define done as identifying why usage does not decrease or documenting the reproduction and limitation.
