test_get_nonlinear_path() failed for Panda #302

Closed ZhekaHauska closed 2 years ago

ZhekaHauska commented 2 years ago

Coppeliasim version: 4.1.0 for Ubuntu 20.04 PyRep version: 4.1.0.2 cloned from github Python version: 3.9

I've run tests/test_arms_and_configuration_paths.py and test_get_nonlinear_path() has failed with error:

[sandboxScript:info]   Simulator launched, welcome!

I had this issue too. For me, at least, the issue was that I had installed PyRep when my COPPELASIM_ROOT was pointing at the wrong version of Coppelia (4.5). When I switched to the right version (4.1), I failed to also reinstall PyRep, and this was the error I encountered. Re-running pip install -e . in PyRep after making sure the ROOT was properly set fixed it for me.

I had this issue too. The Coppeliasim terminal shows error: External call to sim CallScriptFunction failed (getNonlinearPath@PyRep): Error in script Function. The Python terminal shows error: The call failed on theV-REP side. Return value: -1.

I use: Ubuntu 22.04 Coppeliasim version: 4.1.0 for Ubuntu 20.04 Pyrep4.1.0.3 Python3.10.13

This error does not happens all the time, When I use EndEffectorPoseViaPlanning and a manipulation policy network that is trained by myself, the error sometimes shows. When I use action given by the RLBench demo, there is no error. That means the present of the error seem to be related to the action. I make sure that the action format is correct because in some case everything goes well.
