Size mismatch error

[nightrain-vampire]

When I load weight from genforce format, it reports error as follow:

RuntimeError: Error(s) in loading state_dict for StyleGAN2Generator:

After I check the stylegan2_generator.py, I found that the default value of 'fmaps_base' is said to be 16 << 10, but actually it is 32 << 10 in the python code. When I change the 'fmaps_base' into 16 << 10, the code works?

However, in the genforce (where I obtain the model weight), the 'fmaps_base' is 32 << 10! It seems that the same parameter does not work for the same model??

Can anyone tell me what happens? Thank you very much!
