This example shows how to create a Python virtual environment.
Load modules
First, switch to the new software stack
$ env2lmod
or, set your default software stack to the new software stack
$ set_software_stack.sh new
Load a Python module
$ module load gcc/6.3.0 python/3.8.5
Create a Python virtual environment
The option --system-site-packages includes Python packages from host Python also in the virtual environment.
$ python -m venv --system-site-packages myenv
Activate the virtual environment
$ source myenv/bin/activate
Check the python packages included in this environment
(myenv)$ pip list
You can install new packages inside this environment
(myenv)$ pip install --upgrade pip
Deactivate the Python virtual environment
(myenv)$ deactivate
