"""
Script for checking various elements of the runtime environment and print a large amount of diagnostic information.

This is meant to be used for debugging environments used with MONAI, but doesn't directly need MONAI itself. It will
print information about the environment including trying to get installed packages, test PyTorch with CUDA, and then
have MONAI print its debugging information if no errors encountered. If MONAI is not installed this script should still
work and produce useful information.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
