Python and NumPy Versions:
Python 3.11.7
Runtime Environment:
win11
Context for the issue:
I've been trying to install Manim so that I can create mathematical animations, but I encountered an error with NumPy when trying to install it using this command: python -m pip install manim. To resolve it, I just decided to install NumPy individually and came across this error. I'd greatly appreciate it if someone helped me troubleshoot this bug.
