Unable to Knit To PDF the R-notebook containing Python code

I am KNIT TO PDF this R-notebook containing the following Python code:

enter image description here

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

t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2*np.pi*t)
plt.plot(t, s)
plt.xlabel('time (s)')
plt.ylabel('voltage (mV)')
plt.grid(True)
plt.savefig("test.png")
plt.show()

When I choose Knit To PDF, this error appears:

This application failed to start because it could not find or load the Qt platform plugin "windows" in "". Reinstalling the application may fix this problem.

enter image description here

On the other hand, when choosing to Knit To PDF a R-notebook that contains only R code, everything works fine.

Could you please help me resolve this error?
