/home/admin/TTS/TTS/tts/models/tacotron2.py:331: UserWarning: __floordiv__ is deprecated, and its behavior will change in a future version of pytorch. It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). This results in incorrect rounding for negative values. To keep the current behavior, use torch.div(a, b, rounding_mode='trunc'), or for actual floor division, use torch.div(a, b, rounding_mode='floor').

Check the device type of the tensors at the error line. Move them all to either GPU or cpu and run.

@p0p4k Can you elaborate a bit, please? I'm having the same problem.

@BrukArkady The answer is given by @p0p4k. To be precise, you should change line #3150 of functional.py from:

return torch.binary_cross_entropy_with_logits(input, target, weight, pos_weight, reduction_enum)

to:

return torch.binary_cross_entropy_with_logits(input.cuda(), target.cuda(), weight, pos_weight.cuda(), reduction_enum)

For precise analysis of the error, append the following code, you can see the tensors' respective devices. In the TTS/TTS/tts/layers/losses.py file,

#add immediately above L193
tensors_to_check = [x.masked_select(mask), target.masked_select(mask), self.pos_weight] 
for t in tensors_to_check:
    try:
        print(f'tensor {t} is on GPU device - {t.get_device()}
    except:
        print(f'tensor {t} is on cpu'}

#add immediately above L197
tensors_to_check = [x, target, pos_weight=self.pos_weight] 
for t in tensors_to_check:
    try:
        print(f'tensor {t} is on GPU device - {t.get_device()}
    except:
        print(f'tensor {t} is on cpu'}

Then you can just add tensor.cuda() to change a tensor's device to GPU. You can do this directly without doing the above step as well.

Would prefer doing the changes in TTS file, rather than Pytorch library.

Got it. Thanks.

Then again one issue is if you are using a machine with no GPU, we have to write if-else for that. Can you make a PR?

I'm afraid I can't right now. I'll look into it once I get some spare time.

same exact issue here... can someone comment on this issue when it is fixed, so i can try again... Thanks

Fixed by #1872
