Unconditional Generation Training Time #42

Open BenoitWang opened 1 year ago

BenoitWang commented 1 year ago

Hi @sharvil @Andrechang @JCBrouwer thanks for this implementation.

My issue is about the training time for unconditional generation. It takes me about 5 hours/ epoch on 1 * RTX8000 and most of the time is spent on loss.backward(), with the unconditional setting in #5, I wonder:

  1. Is this common?
  2. Any suggestions for acceleration please?
  3. From how many epochs that you start to have good-quality generations?

Thanks in advance.
