Hey,

Love your project! Small contribution from me - colab demo with your inference helper wrapper.

Cheers,

Hi all, Thanks for putting this together.
The colab demo no longer works with the change in pytorch versions. Adding a cell to downgrade pytorch works.

!pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
