Unhandled descriptor set followed by segmentation fault

Hi,

I recently installed Isaac Gym (preview 3) and I’m trying to run the included examples. A window appears and the animation seems to run for 1-2 seconds but then I’m greeted with these messages on the terminal:

(isaacgym) nikhil@lambda:~/projects/isaacgym/python/examples$ python 1080_balls_of_solitude.py

Any pointers to solve this would be really appreciated.
Thanks!

Hi @nikhilweee,

Your problem is here:

WARNING: lavapipe is not a conformant vulkan implementation, testing use only.

Your system doesn’t seem to be finding a compatible NVIDIA GPU. You need to make sure you have a Pascal or later generation GPU, and that it’s visible in vulkan-info - there should be some more info on this in the Troubleshooting section of the install.html documentation.

Take care,

Hi @gstate

I have the same problem with some of the examples, with other not, I am using a 980ti which I think is in the Maxwell 2.0 architecture, it is listed in vulkaninfo, but it will still not work due to the wrong architecture?

Greetings,
Nic
