Questions about position embedding

[hxy-123-coder]

Thanks for your great work! But I have some questions about code. Is the BeatGANsAutoencModel in unet_autoenc.py counterpart with the encoder of UNet? But the tensors of pos_emb and pos_emb_new seem not to be used in the model. Does it not use the position embedding or I misunderstand? Sincerely looking forward to your answer!
