Thanks for your great work, when i try to train the giraffe use the FFHQ , i meet a error:

When i change the Shuffle (False) in the dataloder , it works. but the program stuck here with no GPU running:

      _(actvn): LeakyReLU(negative_slope=0.2, inplace=True)
    )
  )
)

Have you downloaded the dataset? As pointed out in the download script, we do not provide the images for FFHQ - you can find download links in the official repo.
