FastSpeech2 training example
Hi all!

I couldn't find any examples of FastSpeech2 training. The only thing that I've found was the data preprocessing [tutorial](https://docs.nvidia.com/deeplearning/nemo/user-guide/docs/en/stable/tts/datasets.html)

Can anyone tell me if there is a py script such as those for tacotron2 and other models? And, is there an example of a config file?
