Google Collab training notebook is not working

Did anyone tried Google Colab training here: https://colab.research.google.com/github/rmcpantoja/piper/blob/master/notebooks/piper_multilingual_training_notebook.ipynb

This is not working for me as piper-phonemizer is not being loaded and Preprocess dataset sections fails.

Anyone got a workaround or tried this? What's your experience with Colab training currently?
