I’m able to run most of the examples with the PhysX engine (both, physx and physx_gpu options work). However, when using flex, I get a Segmentation fault error. For example, when running
python soft_body.py --flex, I get the following error:
Importing module ‘gym_37’ (/home/aa/isaacgym/python/isaacgym/_bindings/linux-x86_64/gym_37.so)

I followed all the instructions for installation in a conda environment (including the troubleshooting section in the documentation). On running vulkaninfo, I get the following output for VkPhysicalDeviceDriverProperties:
driverID = DRIVER_ID_NVIDIA_PROPRIETARY driverName = NVIDIA driverInfo = 460.32.03 conformanceVersion = 188.8.131.52
I’m running this on Ubuntu 20.04 with an RTX 3080 and CUDA version 11.2. I’ve also tried running this on Ubuntu 18.04 with a laptop GTX 1060 and that works perfectly fine.
Would appreciate any help troubleshooting this.
