weights_delta in GAN Inversion

[yuxu915]

Hi, thanks for your great work! to edit a real image, I'd like to save the latent code files and weights_delta files, so that I don't need to run gan inversion next time. I save them as .npy files, however, when I try to load them, something wrong with "weights_delta" ValueError: only one element tensors can be converted to Python scalars

Any hints would be helpful!
