so on mac download and bash Miniconda-latest-MacOSX-x86_64.sh
cd ~/bin # or other place that is in $PATH
ln -s ~/miniconda3/bin/conda conda
conda install pip
~/miniconda3/bin/pip install conda-workon
conda create -n python3 python=3
conda workon python3
# etc. e.g.
conda install jupyter
Now always to launch jupyter or use python, you need to choose the environment and launch a subshell (virtualenv kinda)
conda workon <env>
jypyter notebook
One idea would be to have a separate environment for jupyter
conda create -n jupyter python=3
conda workon jupyter
jypyter notebook
