Running noisy.py doesn't produce any logging output

[ElonSatoshi]

$ python3 --version; pip3 --version  
Python 3.7.3
pip 20.2.1 from /home/elonsatoshi/.local/lib/python3.7/site-packages/pip (python 3.7)

$ python3 ./noisy.py --config config.json --log debug

It outputs nothing, until I hit Ctrl-C to close it, then it outputs a huge Python error message of the kind that usually occurs when you Ctrl-C a Python script.
