Dealing With Warnings resulting in Application Fatal Errors in windows mode
When warnings are emitted in windows mode (no console available) the warning messages can't be correctly output and the application exits with an error message. This problem doesn't usually interfere with the application features, but it's very inconvenient and ugly.
To filter out warnings and avoid the problem, you can use the warnings module, part of the Python standard library.
It allows suppressing warnings like this:
import warnings warnings.simplefilter('ignore')
See the warnings module in the stdlib for more options.
