Issues with "Training an audio keyword spotter with PyTorch" tutorial

[psiphi75]

I have followed the Training an audio keyword spotter with PyTorch tutorial, on a clean install of Ubuntu 18.04.

I have found the following minor issues:

• The tutorial did not mention to install pyaudio.
• The tutorial did not mention to install onnx - I used the following command conda install -c conda-forge onnx=1.4.1
• The tutorial has a few typos and other mistakes, but I could easily navigate around them (e.g. "GRUKeywordSpotter.ell" in the tutorial is actually "GRU128KeywordSpotter.ell")

Good point. The pyaudio setup was mentioned in the first audio tutorial. ONNX setup is missing from all our docs. Thanks for reporting these doc bugs.

Most of these issues are fixed and "onnx" is listed in the requirements.txt file in the ELL repo.
