Cannot run on Colab

[TueNguyen2006]

I ran this Colab file "https://colab.research.google.com/drive/1vyqbBzBDpgNhjGGuGsiVJb336-WDunOv?usp=sharing", and I performed the environment setup and setup process smoothly. However, when it came to the inference step, it encountered this error.

By replacing line 30 of numerical.py from matplotlib.use(‘TkAgg’) to matplotlib.use(‘Agg’), this error will be resolved.
