Below are 3 methods we can try to find the version of an installed python package. We shall use
scipy as an example.
Method 1 – For pip 1.3 and above:
pip show scipy
Method 2 – Alternative (works with older versions of pip):
pip freeze | grep scipy
Using version attribute
Method 3 – Launch python/ipython, then execute the commands below:
import scipy scipy.__version__
Reference for Method 1 is here. Reference for Method 2 is here.
