Clearly missing the src.utils.profiler and src.utils.math_utils modules

[R2008KK]

Running main.py causes the errors:

These modules are missing from your GitHub project. Removing the import of these modules from init.py causes the program to terminate immediately with an error:

I tested it on Python versions 3.8, 3.9, and 3.10. PyCharm is not installed.
