Hi,
I’m using torchaudio v0.3.1 and I’m getting this error while I’m running torchaudio official example in google colab,

module 'torchaudio.transforms' has no attribute 'DownmixMono'

If you open to degrade, this works to me.

conda install pytorch==1.1.0 torchvision==0.3.0 cudatoolkit=10.0 torchaudio=0.2.0 -c pytorch
