Thanks so much. I misunderstood the post you commented.
I have changed the w with w.detach() in focal_loss.py .Then it runs well.
Then i will test the model to check if it reproduces well.

I guess that the derivative for weight
is not supported in binary_cross_entropy
. You can follow this post.

OK. Thanks so much.
I will have a try.
Best regards.

After reading the post you recommended, i think it needs the derivative, but i dont know how to implement binary_cross_entropy_with_logits.
Could you give some suggestions ?

To my knowledge, you dont need the derivative for focal loss weight. So just detach it.
