How to render the environment?

Hi, can I render the box2D tasks during the training? I could not find relevant parameters in algo class.

Does setting plot=True work?

I first got a None type object error. It worked after I added 'plotter.init_worker()' in start_worker() in batch_polopt.py . Thanks!

Interesting. Did you uncomment both lines of plot=True?

Oh, I did not uncomment the second line. It worked after both lines are uncommented. Thanks.

In fact I did not use run_experiment_lite() in my program. If I only uncomment the first line and then call algo.train() I will get None type object error.
