collecting demonstrations in the robosuite

[Nimingez]

After collecting demonstrations in the robosuite env, and then converting them using the conversion script provided, there seems to be an issue of action not being in the scale [-1, 1] . I have collected the demonstrations using "collect_human_demonstrations.py". then python conversion/convert_robosuite.py get_dataset_info.py total transitions: 27087 total trajectories: 35 traj length mean: 773.9142857142857 traj length std: 240.8114106727588 traj length min: 362 traj length max: 1490 action min: -7.500000000000007 action max: 7.5

the actions not scaled down automatically

I think if you clip the actions in the script it will fix the issue, this was also suggested by the authors in one of the previous issues, if I am not wrong.

like so : action = np.clip(action, -1, 1)

Have you successfully collected data and used training for robomimic？ @Dhanushvarma

[Dhanushvarma]

What I have noticed is that, the keyboard interface is binary, and training with "keyboard-interface" collected data results in poor training. I think to overcome this, the solution is to use a "SpaceMouse" or some alternative interface.

Hi, @Nimingez did the action clipping suggestion solve the issue?
