Hi, I just want to try this out. Without CODA it is running fine, but as soon as I use it with CODA I get the following error:

Traceback (most recent call last):
File "\GFPGAN\inference_gfpgan.py", line 98, in
main()
File "\GFPGAN\inference_gfpgan.py", line 67, in main
cropped_faces, restored_faces, restored_img = restorer.enhance(

return torch._C._nn.reflection_pad2d(input, pad)
RuntimeError: "reflection_pad2d" not implemented for 'Half'

It's on a Windows 10 Laptop.

Thanks for your help!
