Hi,
I am working on someone’s code in torch 0.3.
I want to count number of padding so I wrote:
            ys = valid_decoder_inputs[1:,:].view(-1) #true target 
            not_padding = ys.ne(PAD_IDX)
            no_not_padding = not_padding.sum().item()

However torch 0.3 doesn’t support item(). Can you help of how to write this line of code in torch 0.3?
