My rb_bench environment is setup according to documentation.
Particularly for numpy and mujoco I have the following versions:
numpy 1.16.0
mujoco-py 2.0.2.9
However, when I first tried to visualize a rollout in my 'rb_bench' conda environment by calling python scripts/rollout.py --load_dir runs/PickPlaceCan-Panda-OSC-POSE-SEED129/PickPlaceCan_Panda_OSC_POSE_SEED129_2020_09_21_20_07_31_0000--s-0/ --horizon 200 --camera frontview
I get the following error:

It's not the first time I see this error. It is an incompatibility between mujoco and numpy. Where mujoco 2.0.2.9 needs numpy 1.20.1 I believe.
If I upgrade to 1.20.1 by doing pip remove numpy and then pip install numpy that error is fixed but then when I try to visualize the rollout with the command:

If I keep numpy at 17.1 but downgrade mujoco to 2.2.0 the rollouts work, but have yet to test robosuite here... It is stated that robosuite needs mujoco 2.0.2.9.
