what's the effect of the disable_torch_grad_focal_loss in ASymmetricLoss ?

Thank you for your work ! when i read the code of losses.py, i find the variable disable_torch_grad_focal_loss in AsymmetricLoss, but i don't find it appear in elsewhere . so i wonder if the disable_torch_grad_focal_loss is just used for paper's experiment comparing ? and in normal use,do we need to modify it ?

This is an option we experimented with a bit, but didnt have enough room to put in the paper. The gradient analysis with this option is a bit different.

try first the default version (without).
than you can compare results to the one with disable_torch_grad_focal_loss==True, i think in some cases it can improve results.
