Creating and starting a virtual environment for Python 3

Create a directory for a virtual environment:

mathphysics]$ python3 -m venv ./venv/

Activate it:

mathphysics]$ source ./venv/bin/activate

Deactivate it:

deactivate

Pip install (in the virtual environment) requirements.

Go to Manifolds/ (you'll want the requirements.txt file accessible)

pip install -r requirements.txt

Running pip freeze before and after gives a good idea to the user of what pip packages have been installed.

jupyter notebook in this virtual environment

You'll also want to do a

pip install jupyter notebook

because you may be using a jupyter notebook for your local system; check this with

which jupyter

cf. https://www.codingforentrepreneurs.com/blog/install-jupyter-notebooks-virtualenv

If you want to use the virtual environments "version" or set of pip installed libraries, then from https://stackoverflow.com/questions/37891550/jupyter-notebook-running-kernel-in-different-env

pip install ipykernel

# and
# (but read further below because this might not be the right command for your setup)

python -m ipykernel install --user --name ENVNAME --display-name "Python (whatever you want to call it)"

e.g.

python -m ipykernel install --user --name venv --display-name "Python_venv"

Because I only have a single Python 3 kernel, the above command didn't work, but this did:

python -m ipykernel install --user
