Some questions to produce good generation results.

[Adenialzz]

Hi, thank you very much for sharing your clean implementation. I would like to ask you some questions:

1. How much data we need to produce a good generation result.
2. Does the data need to be of the same category (e.g. flowers).
3. Does transformer require pre-training.

Looking forward for your reply, thanks in advance.

Hello, I have also been researching vqgan recently. May I ask if your network has good convergence performance?
