Can I use FFHQ 1024 pre-trained model with PyTorch?

[dk-hong]

I executed PyTorch_version/loader.py with ffhq-snapshot.pkl and it worked well.

However, I didn't work with ffhq-snapshot-1024.pkl.

How can I resolve this issue?

Error messages are below.

Thank you in advance.

just add these after line 231: (as it is written for 256, it lacks mappings for the rest of the network)
