Crash in multi_task_rl.py #24

Closed ahundt closed 4 years ago

I tried running example/multi_task_rl.py and encountered the following error:

The above exception was the direct cause of the following exception:

Hi, Thanks for pointing out. If you run the script a few times, you should find that it succeeds most of the time. Looks like the 'take_item_out_of_drawer' task is flaky. I'll take a look at this soon.
