Installing torchaudio on google colab


I am trying to install the torchaudio library in google Colaboratory notebook. However I get this dependency error:

Is there any workaround to fix this issue ?

Best Regards

I just installed it via pip on Google Colab directly from the GitHub repo and it works fine.

pip install git+git://

Note that you need to install the required dependencies via apt-get first as mentioned in the GitHub repo. Also you need to have PyTorch installed, otherwise you will get an error during the install.


The dependencies I mentioned above are the ones listed for Ubuntu Linux ( Worked fine for me in the Colaboratory Notebook:

apt-get install sox libsox-dev libsox-fmt-all

Actually I was installing it manually and found that I should have installed ‘cffi’ first as additional dependency. However the direct installation via pip you have provided is awesome. Thaanks

Tried the following:

!sudo apt-get install sox libsox-dev libsox-fmt-all
!pip install git+git://

Got the following message:
Successfully built torchaudio

However, got the following error while importing torchaudio:
import torchaudio
RuntimeError: Failed to parse the argument list of a type annotation: name 'Optional' is not defined

Am I missing something?

This worked finally:

!git clone
!git checkout 301e2e9
!python install
