z_list

[rosinality]

For each block half of outputs splitted into z and appended to zs.

If you need to reconstruct then you only need a output z lists. Random zs is used for sampling from the model.

Thanks for your answer!
Why do we need a z list rather than a single z?

[ZhouCX117]

Thanks a lot! I think I have more understanding of the glow model.

Hi， It is me again!
I can't understand the self.scale = nn.Parameter(torch.zeros(1, out_channel, 1, 1)) and "out = out * torch.exp(self.scale * 3)" in the ZeroConv2d module. Could you please tell me what role this plays? I appreciate your answer!

`if args.n_bits < 8:
image = torch.floor(image / 2 ** (8 - args.n_bits))

        image = image / n_bins - 0.5`

Hi, a more question. Does this code mean image=image/256-0.5? What is the good of this way?

[ZhouCX117]

loss = -log(n_bins) * n_pixel
Hi~ Why do we need this constant loss? I appreciate your answer! Thanks a lot!

Hi, do you train the face for image_size 256*256? What is the setup of hyperparameters? I set the batch=2 and keep the other, the results are so bad.

[ZhouCX117]

The parallel train can't work. And if I change the n_block from 4 to 6 as suggested by the paper, the loss becomes Nan.
