How so?  The basic use is simple

https://docs.python.org/3/library/venv.html

python -m venv /path/to/new/virtual/environment

I group all my python project in a python directory so it would be

python3 -m venv new_project
cd new_project
. ./bin/activate
python -m pip install matplotlib
python -m pip install numpy
etc.

You can get creative with different python versions but I stick with the 
basics. I need to use python3 initially since that's the base install. 
After activating the environment it's just python and refers to the python 
interpreter in the bin directory of the venv directory. Similarly all the 
packages are placed in lib/python.3x/site-packages. You are not trying to 
install potentially conflicting packages in a global site-packages.

To get back to the global environment 'deactivate'

https://python.land/virtual-environments/virtualenv

That's a more coherent explanation and points out the minor differences 
between Windows and Linux.

Anaconda can be used with virtual environments too. If you're a real 
masochist you can use both but I would suggest sticking with one or the 
other. I had problems installing packages I needed with Anaconda so went 
back to standard python for most purposes. Esri favors Anaconda so I do 
have it on one machine.

fwiw, VS Code allows you to select the interpreter and thus the venv. For 
example if you've installed keras in a venv and switch to a different venv 
you don't have access to keras anymore.
