Backend TkAgg is interactive backend. Turning interactive mode on.

This message usually appears when using Matplotlib in a Python script or notebook. It means that the interactive mode for the TkAgg backend has been turned on, which allows for real-time plotting and user interaction. This can be useful for debugging or exploratory data analysis, but it can also slow down performance for large datasets. If you do not need interactive mode, you can turn it off by adding the following line at the beginning of your script:

import matplotlib
matplotlib.use('Agg')

This will switch the backend to Agg, which is a non-interactive backend that is optimized for generating static images.
