Hi,When I ran the executable 'pick-demo', I encountered the following error:

No module named denso_control.controllers INFO 00:46:00,627 (transport.console.pick_and_place) [init: 227] Only run in OpenRAVE.

I am looking forward to your help to solve this problem. Thank you very much

Hi @aip1996, this looks like a version incompatibility issue.

Could you try to check out commit: 79a9b7df8996c88e56888c0ce861bd7935e929da (toppra) and try running the example again?

Please let me know if it works for you.
