[FIXED] Spyder is restarting kernel without error message

Issue

Trying to run this example script in spyder IDE version 5.1.5

import matplotlib.pyplot as plt
import numpy as np
import matplotlib.mlab as mlab
import matplotlib.gridspec as gridspec

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

dt = 0.01
t = np.arange(0, 10, dt)
nse = np.random.randn(len(t))
r = np.exp(-t / 0.05)

cnse = np.convolve(nse, r) * dt
cnse = cnse[:len(t)]
s = 0.1 * np.sin(2 * np.pi * t) + cnse

fig, (ax0, ax1) = plt.subplots(2, 1)
ax0.plot(t, s)
ax1.psd(s, 512, 1 / dt)

plt.show()

leads to

Restarting kernel...

without any further error message. Python version is 3.8.12, intalled with Anaconda.

Solution

Thank you Daniel Althviz for the hint.

This solution solved the problem:

conda install freetype=2.10.4
