When creating a Python project, you do so in a virtual environment (or maybe you don't?).
pip install your_module
Then you install packages for your project. So how do you know what all the installed modules are?
Easy, there's a command
So if you want to know which version of a module you have, combine with grep.
λ ~ pip list | grep 'tensorflow' tensorflow (1.14.0) tensorflow-estimator (1.14.0)
If you are using Ubuntu Linux or similar, you may have the odd situation in which you have both pip, pip3, python and python3 installed. Did the Ubuntu creators have some evil plan?
In that case, just add 3 after the pip command. For other operating systems, you can just use Python and pip.
