Tacotron2 To onnx Model Conversion Help

[shubhank008]

I was checking out the tacotron2_onnx.py model conversion program and tried running it on my google colab notebook (the one I use for synthesis of my taco2 model) but it throws error "Modules not found".
I believe I am missing some steps here by directly trying to execute the .py class from my colab notebook, so wanted to ask for some pointers on what's the proper way to convert my Taco2 model to ONNX so I can use it on other platforms (windows/mobile).

Secondly, do I need to convert my HifiGan to ONNX too ?
