AttributeError: 'Upsample' object has no attribute 'recompute_scale_factor'

Question

I get error on line x_stats = dec(z).float().

import torch.nn.functional as F

z_logits = enc(x)
z = torch.argmax(z_logits, axis=1)
z = F.one_hot(z, num_classes=enc.vocab_size).permute(0, 3, 1, 2).float()

x_stats = dec(z).float()
x_rec = unmap_pixels(torch.sigmoid(x_stats[:, :3]))
x_rec = T.ToPILImage(mode='RGB')(x_rec[0])

display_markdown('Reconstructed image:')
display(x_rec)

I tried to downgrade and reinstall the torch package but that didn't help the issue. My package version is torch==1.11.0

Answer 1

Install Torch version, this will solve the issue
