I was trying to use the Matplotlib module from Python, but every time i try to execute a function that should open a new window, it works, but returns qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "" in the terminal.
I think that it doesn’t like the fact that i use wayland, but do you have any idea about how to solve that ?
A script that displays the error :
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0, 1)
plt.plot(x, x*x)
plt.show()
