Example notebooks will not work with the next release

• TIA Toolbox version: 1.1.x?
• Python version: Python 3.7
• Operating System: Linux

In the new version of TIAToolbox we have dropped the support for python < 3.8, while Colab uses python=3.7. I think this means that non of example notebooks will work in Colab after merging develop in master simply because users cannot install the toolbox via pip install tiatoolbox. We didn’t see this coming when we dropped the support of python 3.7.

One (really) nasty solution is to add a cell on the top of the notebook in which we install a Python 3.8 using Conda, like this

!wget -O mini.sh https://repo.anaconda.com/miniconda/Miniconda3-py38_4.8.2-Linux-x86_64.sh
!chmod +x mini.sh
!bash ./mini.sh -b -f -p /usr/local
!conda install -q -y jupyter
!conda install -q -y google-colab -c conda-forge
!python -m ipykernel install --name "py38" --user

however, this is not idea at all because it’s not guaranteed to work all the time and there might be tons of problems with dependencies. Alternatively, we can consider having support for Python 3.7 back, if possible.

@mostafajahanifar I am adding support for Python 3.7 back for now. Once Colab starts supporting Python 3.8 we will remove Python 3.7 support.

In case it helps, I can also highly recommend https://deepnote.com/ for hosting example notebooks. When Google stopped maintaining Colab, I switched my project’s example notebooks to Deepnote and I couldn’t be happier.
