I met the 72956 segmentation fault when I tried to train the task with Pixels suffix like FrankaPickPixels.
Besides, I have finished the training successfully with the task without the Pixels suffix. It seems that the segmentation fault is not triggered by pytorch.
I'm using Isaac Gym Preview 4 on Ubuntu 20.04.
Here is the output after running python tools/train_ppo.py task=FrankaPickPixels
