I have a python program, say, train.py. It can be run in anaconda prompt by typing: 

python train.py

In train.py, some part is written for drawing and saving figures:

import matplotlib.pyplot as plt
....... #I omit these codes
plt.savefig(....)
plt.show() #this will produce a figure window 
plt.close()

In implementing the program, some figures are to be generated, which will bring the program to a temporary halt, even though plt.close() present. Then I need to manually close the pop-up figure window due to plt.show() and continue the program. How to avoid this inconvenience.

It is noted that spyder can run the program continuously, with figures displayed in its console.

  • Is there a reason you would use `plt.show()` to be immediately followed by an attempt to close that window? – roganjosh Jul 14 '17 at 20:23
  • I still want to see these figures, and then they are closed by coding – jwm Jul 14 '17 at 20:24
  • Have you read the answer [here](https://stackoverflow.com/questions/11140787/closing-pyplot-windows)? Did it help? – roganjosh Jul 14 '17 at 20:27
  • Do you want the figures to be displayed for a certain time period, say 10 seconds, and then the windows be closed? – Rory Daulton Jul 14 '17 at 20:36

plt.show() is meant to be used once in a script to show all figures present. So you can create your figures and show them all at the end

fig1 = plt.figure(1)
# do something with figure 1

fig2 = plt.figure(2)
# do something with figure 2

plt.show() # show both figures
