NameError: name 'defaultParams' is not defined while running the .exe converted using Pyinstaller

I successfully converted the main.py script using pyinstaller. However the below stated error is thrown while executing the .exe file for the same.

MatplotlibDeprecationWarning: Matplotlib installs where the data is not in the mpl-data subdirectory of the package are deprecated since 3.2 and support for them will be removed two minor releases later.

Supposedly, all you can do to fix this is to downgrade your matplotlib to the version:

pip install matplotlib==3.2.2

Apparently, the latest version of matplotlib meddles with the environment variable in the windows path.
