Future of Python 3.7 and Google Colab

Question

Tried to install feature/cam16_hke_hellwig2022 in Google Colab, and realised colour now requries Python 3.8, and Colab is stuck on 3.7. I tried changing the version requirement in the pyproject.toml, and it installed, but submodules don't seem to load.

Are there any work arounds?

And is there any plan on supporting Google Colab while it's on 3.7?

Hey @ilia3101,

The Google Colab situation is rather bad and there is a thread here that you might want to weight in: googlecolab/colabtools#2165

I really do hope that they will not can it...

That being said, you should be able to install Colour has follows:

import sys

!pip install colour-science
!pip install --upgrade numpy

!pip uninstall -y colour-science
!if [ -d "colour" ]; then rm -rf colour; fi
!git clone https://github.com/colour-science/colour && cd colour && git fetch && git checkout develop && cd ..;
sys.path.append('colour')

!python -c "import imageio;imageio.plugins.freeimage.download()"

sys.path.append('colour')
