Python dependencies visualization using pydeps

To see what Python modules are available on my system I can run

pydoc3 modules

One of the modules is pandas. Here's a script that just loads pandas module:

cat load_pandas.py 
import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)
import pandas as pd 

When the script is run nothing happens

python3 load_pandas.py

I have pydeps installed:

pydeps --version
pydeps v1.12.17

Output of analysis by pydeps:

pydeps -o myfile.png --show-dot -T png --noshow load_pandas.py
