Train a model with 1 step of flow first.
Then use this model to warm-start a model with 2 steps of flow.

Hi,
Thanks for your reply. I indeed started training a 1-flow using the LibriSpeech train-clean-100 data using a modified unconditioned version of Flowtron. I then used the trained flow to warm-start a 2-flow architecture. However at inference there is nothing but noise: https://drive.google.com/file/d/1V7sX3Ma3RFBo6lNSCUxSsNjP3Y_HmAZo/view?usp=sharing.
I was expecting at least some babble noise.
Any hints on when is a goot point to start the second-flow training? Should I train more? Should I lower the learning rate?
Below are the loss curves for the 1st flow:
Thanks!

The validation loss for your 1-step of flow model is starting to plateau.
Use this model to warm-start a 2-steps of flow model. I assume the validation loss will go down.
You can alternatively try the same experiment on LJS.

I warmstarted a 2 flow model from the 1 flow weights and continued training. Training and validation losses are as below:
Still no speech-like output at inference.

I additionally started a subsequent 3 flow model, as well:
The output is as follows:

So I assume that this architecture might not be complex enough to estimate a multispeaker latent space. I will try to do the same thing on LJSpeech -- perhaps the conditions are simpler.
Thanks!

@adrianastan if you trained a model with speaker embeddings, what happens if do this:
flowtron.infer(flowtron.forward(audio, speaker), other_speaker)
from flowtron.
I did not use speaker embeddings, just a multispeaker dataset. I removed all conditionings of the flow.
