Valid grasps not displayed in scene generation about acronym HOT 3 OPEN

Hi, this was tested under 18.04. Is there any output/error message that you get when executing the code?

Another possibility that comes to mind is that there might be no valid grasps in the particular scene you are looking at (if all of them are in collision). You can test this by e.g. adding print(len(gripper_markers)) in line https://github.com/NVlabs/acronym/blob/main/scripts/acronym_generate_scene.py#L115 and check that the output is greater than zero.

Hello,
thank you for you fast reply. So it works under Ubuntu20.04, too. I just had to uncomment or exit the first window which appears containing only the objects in the scene.

So I guess it is normal, that not every possible, collision-free grasp is displayed?
Again, thanks!

Yes, not every grasps is shown, the visualization will become very slow, but you can increase the parameter --num_grasps_per_object, see here:
