Thx for raising this issue. I will work on Py3 compatibility soon. I think it should be a small change.

[kolemikko]

I already updated my Wavegan files to work with Python 3.x, quite small change after all. I can share them if it helps!

[cclauss]

Please share them.

[kolemikko]

Should I send them to you @chrisdonahue ? So you could check the code and push the changes for everyone.

I noticed the print error from python2 in my python3 environment. Then I tried these 2 lines and it works fine now. 2to3 -W train_wavegan.py #change python2 to python3 automatically autopep8 -i train_wavegan.py #fix the tab issues
