mel_surrogate:

criterion: l2
real: target_mel
fake: mel_predNote that I have not provided (and will not provide) some of the things that you would need to make these step configs work, notably the DVAE. There are also some "weird" things like transitioning from 22kHz audio to 24kHz audio which were driven by my late stage decision to use a vocoder.
I strongly recommend you do not actually attempt to train your models with DLAS. It is a very rough sandbox I have built and maintain for my personal use. It is not going to be fun to get working for someone else. I would highly recommend doing your training in something better supported like pytorch lightning or fairscale. Hopefully the above configs can help you decipher what the pipeline and loss structure looks like.

@neonbjb hi, would you like to share the config file for CLVP model, thanks a lot.
Hello! I found the GptVoiceLatentInjector injector. It looks like it's for inference, anyway it's not difficult to return losses using it. But I still wanted to clarify which injector you used for training. Because I also found a GptTtsDataset dataset that returns quantized_mels, as I understand it, these are mels pre-processed by dVAE, but GptVoiceLatentInjector takes wav as input.
