Install Ecole, Pytorch, and Pytorch Geometric in the same environment

[AntoinePrv]

Sometimes, when trying to install Ecole, Pytorch, and Pytorch Geometric in the same environment, conda runs indefinitely or fails.

If this command is not working

conda create -n myenv -c pytorch -c conda-forge ecole pytorch pytorch_geometric

You can get pytorch from the conda-forge channel

conda create -n myenv -c conda-forge ecole pytorch pytorch_geometric

Otherwise, if you find conda is still taking too much time, or not resolving, you can try to install packages with Mamba (an alternative, faster, Conda package manager).

conda install -n base -c conda-forge mamba
mamba create -n myenv -c pytorch -c conda-forge ecole pytorch pytorch_geometric
