Switch between two versions of python in the same environment
1
I need to build a pipeline which was written in python 2.7. A few dependencies like matplotlib have been upgraded since then to work with Python 3.x, but the original pipeline code is incompatible with python 3.x syntax. While building, I am unable to use Python 2.7 as matplotlib and thereby mayavi refuse to be installed after that. And if I build everything using Python 3.x the final code does not execute because the code is incompatible with python 3.x.
The pipeline I need to run is https://github.com/aestrivex/ielu
Please help.

This sounds like an XY problem. Why exactly can't you use matplotlib in python 2.7? What is your Ubuntu version? are you using the OS default python, or a 3rd party installation such as anaconda?

@steeldriver looks like the repo mentioned wants to use anaconda

one possible course of action is to clone that repo and upgrade it to python3 then submit a pull request back to the repo ... however as @steeldriver suggests its probably easier to write your new code using python 2.7

You can use pyenv to switch between python versions.
# Get Pyenv
curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
# add pyenv to ~/.bashrc
echo -e "export PATH="/root/.pyenv/bin:$PATH" n eval "$(pyenv init -)" n eval "$(pyenv virtualenv-init -)" " >> ~/.bashrc
source ~/.bashrc
# install python 3 via pyenv
pyenv install 3.5.6
# verify
pyenv versions
# pyenv local <version> : use this to set python version per directory.
# pyenv gloal <version> : use this to set python version globally.
