ImportError: Cannot imporrt name SystemRandom

Reproducing code example:

import numpy as np
import matplotlib.pyplot as plt
import time
import numpy as np
ysample = np.random.randint(-50, 50, 100)
xdata = []
ydata = []
plt.show()
axes = plt.gca()
axes.set_xlim(0, 100)
axes.set_ylim(-50, +50)
line, = axes.plot(xdata, ydata, 'r-')
for i in range(100):
    xdata.append(i)
    ydata.append(ysample[i])
    line.set_xdata(xdata)
    line.set_ydata(ydata)
    plt.draw()
    plt.pause(1e-17)
    time.sleep(0.1)
plt.show()
