sim.plot3D() don't work in my pycharm APP

[liujw1007]

I want to show the structure in the official example below：

import meep as mp import numpy as np import math

cell_size = mp.Vector3(2,2,2)

A hexagon is defined as a prism with six vertices centered on the origin

vertices = [mp.Vector3(-1,0), mp.Vector3(-0.5,math.sqrt(3)/2), mp.Vector3(0.5,math.sqrt(3)/2), mp.Vector3(1,0), mp.Vector3(0.5,-math.sqrt(3)/2), mp.Vector3(-0.5,-math.sqrt(3)/2)]

geometry = [mp.Prism(vertices, height=1.0, material=mp.Medium(index=3.5)), mp.Cone(radius=1.0, radius2=0.1, height=2.0, material=mp.air)]

sim = mp.Simulation(resolution=50, cell_size=cell_size, geometry=geometry)

sim.plot3D()

but it seems that the command ‘sim.plot3D()’ don't work for me. Here is the information in the run window:
