Issues running the Colab notebook

[xperroni]

I was trying to run the Google Colab notebook in order to compile a MyriadX Blob with 3 shaves, but ran into numerous package compatibility problems — some of which are down to the installed version of PyTorch, which I wasn't able to correct. After a lot of trial-and-error I was able to perform the compilation procedure locally, see the script below for reference:

# For some reason this line fails in Colab, which is why I decided to run the compilation procedure locally.
pip install --extra-index-url https://download.pytorch.org/whl/lts/1.8/cu102 \
torch==1.8.2 \
torchvision==0.9.2 \
torchaudio==0.8.2 

pip install -U mmcv-full==1.3.13 mmsegmentation==0.18.0

pip install gdown
