mocap_demo error (matplotlib problem?): [GLFWApplication _setup:]: unrecognized selector sent to instance 0x10f0b3ae0 #80

Closed bibbygoodwin closed 4 years ago

bibbygoodwin commented 5 years ago

Currently something in the package is resulting in this error when I run the mocap_demo script. The error seems to be the same as #deepmind/dm_control#62, and given that the author of that issue put it down to something involving matplotlib it is possible that this is the root cause.

One of the replies to that issue from @saran-t (https://github.com/deepmind/dm_control/issues/62#issuecomment-438239756_) failed to reproduce the error because, it seems, they ran into the more standard matplotlib on OSX in virtualenvs problem, where a "ImportError: Python is not installed as a framework." error is thrown. If @saran-t sets the matplotlib backend to 'TkAgg' following the solution here: https://stackoverflow.com/questions/21784641/installation-issue-with-matplotlib-python then they should be able to reproduce this error?

The minimal script required to trigger the error:

import matplotlib.pyplot as plt
from dm_control.suite import humanoid_CMU
env = humanoid_CMU.run()
fig = plt.figure()

If instead I call the last 2 lines in the other order I get no error i.e. 

import matplotlib.pyplot as plt
from dm_control.suite import humanoid_CMU
fig = plt.figure()
env = humanoid_CMU.run()

@bibbygoodwin Hi, what i suggest is trying to use cv2 to do the visualisation

import cv2
...

for i in range(max_frame):
  cv2.imshow('demo', video[i])
  cv2.waitKey(100)
