Error: signal 11

When I run bash online_evaluation_rlbench/eval_peract.sh, this error occurs, how to solve it? Thank you!

Hi,
this seems to be a CoppeliaSIm specific issue. I admit that these are the hardest to debug because the error messages are not helpful at all.

I suppose you followed our installation instructions. One suggestion is to make sure that the Coppelia version is the appropriate for your Ubuntu version.

My CoppeliaSim installation followed the instructions given and the version is Ubuntn20.04.

Ok, thanks for providing this info! There are two things:

1. I ran into the exact same issue on another machine. The truth is, I never resolved it on that machine, since I had another machine successfully running RLBench.

2. Due to that, I googled the issue you're having. I tried things from this thread Arise Error signal 11 when running task.reset() stepjam/RLBench#146 but it didn't work for me. Still, it worked for some people, so maybe it's worth trying.

Unfortunately, I can't help much more since I also don't know how to resolve this. I really hope somewhere online we can find a solution. It's on the RLBench side.
