AttributeError: 'module' object has no attribute 'functional'

[VictorZuanazzi]

Hello,

I am trying to get started with GAN zoo, but I cannot the steps of the instructions don't seem to work for me.

Which python version does it use? Python 2 or 3?

When I run the following line (as per instructions), I get several errors including a 'module' object has no attribute 'functional', which seems to point out to torch versioning issue.

I did not change anything in the code yet.

That's weird. What version of pytorch do you use ?

[VictorZuanazzi]

I am currently using Pytorch 1.1. Other implementations are working allright, but I really could not use the GAN-ZOO

What is your version of torchvision then ?

To check that there isn't an issue over a variable name, can you try to replace the line https://github.com/facebookresearch/pytorch_GAN_zoo/blob/d87a196fc382d6904180c6d9e241458bcb37ce22/models/utils/image_transform.py#L71 by return torchvision.transforms.functional.to_tensor(img) ?
