Discuss about Stochastic duration predictor and adversarial training

[ductho9799]

In Section 2.1 of VITS-2, I see "Our proposed duration predictor and training mechanism allow for a learning duration in short steps, and the duration predictor is separately trained as the last training step, which reduces the overall computation time for training."

So, I think the duration predictor network is seperately. When training Duration Predictor as the last training step, and the others modules such as: TextEncoder, Posterior Encoder, Generator, Normalizing Flow are freeze.

Yes, you are right. See this thread for more discussion. I will add it later on or wait for someone to send a PR =)
