How to check the version of Python Modules

If you are wondering how to check the version of the modules that you have with Python, you can pip/pip3 installer to do so.

Let's take a look at a few examples.

Using the "pip list" command:

% pip list | grep spacy

spacy                    3.5.2
spacy-legacy             3.0.12
spacy-loggers            1.0.4

As the pip list command will print out the list of all the installed module's versions, you can pip the command with grep followed by the specific module you are looking for.

Example: Get the list of versions for all installed Python modules:

% pip list
