How to leave matplotlib figure opened after script ends?

Question

Suppose I have the following script plotting a graph for me:

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

img = mpimg.imread('stinkbug.png')
#circle = plt.Circle((0, 0), radius=0.5, fc='y')
circle = plt.Circle((0, 0), radius=100, fill=False, color='b')

fig, ax = plt.subplots()
ax.imshow(img)
ax.add_artist(circle)
fig.show()
pass

Unfortunately, the figure closes after the script ends.

How to prevent that?

UPDATE

If it is impossible for the figure to survive the script, then what is the reason for it? What is the connection between the figure and the script?

Answer 1

You can't. The figure created by your script can't survive after the script has ended. But maybe you do not need that, you can make your script wait for you to close the figure window instead. Just be sure interactive mode is not activated.

import matplotlib.pyplot as plt
plt.ioff()  # Use non-interactive mode.
plt.plot([0, 1])  # You won't see the figure yet.
plt.show()  # Show the figure. Won't return until the figure is closed.
