RuntimeError: Node 'conv_high_res_0' resp. TypeError: conv2d(): argument 'padding'

[stvogel]

Thanks for providing your code for FastFlow. I try to train it but I got the following error:

Traceback (most recent call last):

TypeError: conv2d(): argument 'padding' (position 5) must be tuple of ints, not str

The above exception was the direct cause of the following exception:

I'm not sure what's the error here. I assumed it was the padding-problem (which was a problem between version of torch before 1.8) I'm using torch 1.8 but I cannot find any padding-problems.

Did someone else got this error?

Hi @stvogel, I use torch 1.10.0 and I never got that error. Did you modify the code in some way? If there is a way to solve this issue, I'm ready to fix the code. Best, Alessio

Hi @AlessioGalluccio,

ahh torch 1.10.0 did the trick. Thanks a lot for your hint. Maybe this version should be added to the requirements.txt.

[AlessioGalluccio]

That's a great idea. I updated it. Thank you very much. Best, Alessio

Hi @AlessioGalluccio, I haven't update the version of torch and the code can run. The detial as follow:

Only change this way.

hi, i can't find the file to modify

Hi, @Wangj688 The code fragment @gaowq2017 mentioned is in model.py. It worked fine with torch1.8.2 on windows10.
