Question about label_smoothed_cross_entropy.py

[jun297]

line 222 in label_smoothed_cross_entropy.py updated as the following: From net_output[0].masked_fill_(~constraint_masks, -math.inf) To net_output[0] = net_output[0].masked_fill(~constraint_masks, -math.inf)

With the latest code, I got an error typeError: 'tuple' object does not support item assignment

I fixed by using the previous one. Is there any reason why it is changed?

Which version of pytorch are you using? This is because the problem of in-place operation in the new version of pytorch, for example, >=1.10
