Gym Videorecorder not working with LBFG environment #40

My steps so far:

  • Trained and saved model for LBFG
  • in run.py I highjack the evaluate_sequential()

env = runner.env._envs
env = gym.wrappers.Monitor(env, '/tmp/policy.mp4')
rec = VideoRecorder(env, enabled=True)

then I highjack runner.run(test_mode=True, rec=rec) in EpisodeRunner
by adding
rec.capture_frame()
in the while not terminated loop

afterwards I close the VideoRecorder.

My expectation would be a .mp4 Video. Instead I just get the .json files, which are empty.

Has anybody managed to get a Video out of epymarl?
