ModulNotFoundError matplotlib

[WicardBohnam]

How did you install matplotlib? Import does not install a package.

I went to matplotlib's website and did a bunch of things that it seemed to be telling me to do to get matplotlib. I'm not sure how to check what you're asking, though I'll repost.

import matplotlib.pyplot as plt
import numpy as np

# Fixing random state for reproducibility
np.random.seed(19680801)


N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = (30 * np.random.rand(N))**2  # 0 to 15 point radii

plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.show()

and here's the error:

Error:
