hello, i found bug in pytorch reinforcement tutorial, which is on pytorch.org.i run colab version and it gave me error on this code:
‘’’
env.reset()
plt.figure()
plt.imshow(get_screen().cpu().squeeze(0).permute(1, 2, 0).numpy(),
       interpolation='none')

plt.title(‘Example extracted screen’)
plt.show()
‘’’
and error says:
‘’’
Cannot connect to “None”
‘’’
i haven’t read code yet.so what is solution, is that a bug? and how to fix it.To see whole code, you can go to https://pytorch.org/tutorials/intermediate/reinforcement_q_learning.html 6, this is official website.
