ModuleNotFoundError: No module named 'torchaudio.prototype'

🐛 Describe the bug

Having issues getting the Streamer to import. Have tried importing it like this from torchaudio.prototype.io.streamer import Streamer in folders independent of my cloned audio repo. In this case I had torchaudio installed as a pip dependency, however it seemed like it was possibly trying to reference my local audio repo. I was using torch 1.11.0 and torchaudio 0.11.0 Error:

ModuleNotFoundError: No module named 'torchaudio.prototype

Similarly I’ve tried removing the pip torchaudio dependency and trying to run online_asr_tutorial.py from its location in the audio repository and I still get the same issue.

ModuleNotFoundError: No module named 'torchaudio.prototype

I tried adding

import sys sys.path.append(‘…/…/’)

before the torchaudio import in my local copy of online_asr_tutorial.py under the audio repository but I then encountered this.

Running online_asr_tutorial.py in google colab also gave the same error (with no file modification):
