Playback Demostrations Failed

[jiaqixuac]

I want to replay the demonstrations.

However, when I "python playback_demonstrations_from_hdf5.py --folder ../models/assets/demonstrations/SawyerPickPlace/ --use-actions" under the robosuite/robosuite/scripts/, the program failed the assertion and the robot can't grab the things.

I failed when installing mujoco-py==2.0.2.2 & robosuite==0.3.0 as well as mujoco-py==1.50.1.68 & robosuite==0.2.0. Could you give any suggestion？

BTW, when I installed surreal, it says "ERROR: surreal 0.2.1 has requirement mujoco-py<1.50.2,>=1.50.1, but you'll have mujoco-py 2.0.2.2 which is incompatible." "ERROR: robosuite 0.3.0 has requirement mujoco-py==2.0.2.2, but you'll have mujoco-py 1.50.1.68 which is incompatible." Does this mean RoboTurk collected demonstrations using mujoco-py 1.50.1.68 and maybe incompatible with the current robosuite?

I see the previous issue https://github.com/StanfordVL/robosuite/issues/37

So, it means the RoboTurk dataset does not promise replay using actions, and we can't use the RoboTurk dataset for some imitation learning methods like simple behavior cloning?

Thanks!

Just because the replay fails doesn't mean that you can't use it for simple behavior cloning, or other imitation learning methods! For example, we used the RoboTurk dataset in this work with purely offline learning.

if j < num_actions - 1: env.sim.set_state_from_flattened(states[j+1]) Hey i change this code snippet to above to set state rather than assert state,then robot can perform correctly:)
