Error when running a matplot lib example

Hi all,
New forum user here.
When I run this code from the Matplotlib examples, I get the following error:

Error:

My Code:

import matplotlib.pyplot as plt import numpy as np plt.style.use('_mpl-gallery-nogrid') # make a stream function: X, Y = np.meshgrid(np.linspace(-3, 3, 256), np.linspace(-3, 3, 256)) Z = (1 - X/2 + X**5 + Y**3) * np.exp(-X**2 - Y**2) # make U and V out of the streamfunction: V = np.diff(Z[1:, :], axis=1) U = -np.diff(Z[:, 1:], axis=0) # plot: fig, ax = plt.subplots() ax.streamplot(X[1:, 1:], Y[1:, 1:], U, V) plt.show()

The style is not available, check the styles

import matplotlib.pyplot as plt print(plt.style.available)

This is what I get in Mint

Output:
