Description

Following up on issue #944 for which I have submitted code to reproduce here, the repro code goes through forward, but now fails on backward with a different exception:

https://github.com/fac2003/repro_deepspeed_multi_modality_perceiver_stage_3/blob/main/DeepSpeedMultiModalityPerceiver-from-master.ipynb?short_path=52c54dd

It would be great if the repro code could be tried with potential fixes so that this issue can be fully addressed this time.

Research direction

Start with the reproduction notebook linked in the issue and compare its forward and backward paths under optimization_stage_3. Review issue #944 for prior context, then run the repro to capture the backward exception and test potential fixes. Done means the repro completes backward without the reported exception.
