What does this PR do?
The deepspeed optimizer does not accept the argument
optimizer.zero_grad(set_to_none=...)
. In their optimizer, the name isoptimizer.zero_grad(set_grads_to_None=...)
🤣 We are translating this inconsistency for the user.Perhaps DeepSpeed should change their name to be consistent with PyTorch: microsoft/DeepSpeed#2678
