You are populating items with the mailabs function (which is just one of several, plus you can if needs be write your own if your files/data are in a different structure) Using a suitable one is what the comment there is drawing attention to.
Are you sure that your files are in a format/directory structure that matches?
I’ve seen several cases where people set up their data in the structure for LJSpeech.
I’d suggest you Google both M-AI-Labs and LJSpeech to figure out if your structure matches them (or is some other structure) and make changes as appropriate, until the number of files is non-zero (ie that they’ve all been loaded correctly)
Yes, I did it in LJSpeech way, even names are the same, however only mailabs works without giving any error. I will check it again, and I will come back
Now it’s working. The data path should be ‘more complicated’, as in the exemplary notebook.
Worth mentioning is that i had to rerun couple of times 7th block of commands. Before I had to do something with widgets: Jupyterlab and tqdm_notebook · Issue #394 · tqdm/tqdm · GitHub.
/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:18: TqdmDeprecationWarning: This function will be removed in tqdm==5.0.0
Please use tqdm.notebook.tqdm instead of tqdm.tqdm_notebook
