Import Error about library"torchaudio_augmentations" in colab

[ghost]

Hi, first I would like to say thank you very much for the tutorial, it's really great. ：）

I'm trying to implement the code from the tutorial into colab, but it seems that in “Audio Data Augmentations” subsection, the import encounters problems with cuda version compatibility, I'm not quite sure what's going on, could you please take a look at it?

Here is my colab note: https://colab.research.google.com/drive/1Df2-yf9-tSnYUo8juIhfLTvhSto5Bk7F?authuser=2#scrollTo=GezaZlg7kqgx&line=5&uniqifier=1

Hi there! Thanks for reporting the issue. I've taken a look at your stack trace, and it says that it has problems loading torchaudio's Vol class. This may have to do that your torchaudio version does not match the compiled torch version in your notebook. I would recommend doing a pip3 install torch torchaudio --upgrade.

(copying the stack trace for reference here:)
