Matplotlib in Pycharm - not running

[ALMOKTM]

hey. I'm trying to run a simple code with matplotlib liberty.
I got some errors.

ideas what is wrong?
I downloaded the liberty to my project.
the script:

import matplotlib.pyplot as plt
x=[1,2,3,4]
y=[1,2,3,4]
plt.plot(x,y)
plt.show()

the errors:

Error:

Works on my system:

>>> import matplotlib.pyplot as plt
>>> x=[1,2,3,4]
>>> y=[1,2,3,4]
>>> plt.plot(x,y)
[<matplotlib.lines.Line2D object at 0x7f0fa8bb33a0>]
>>> plt.show()

   

Try reinstalling matplotlib
