Isaac Gym Preview 3 installation error

Hi,

i am trying to install Isaac Gym to my computer following the instructions included in the Isaac Gym Preview 3 Package (index.html). As recommended i installed it in a new conda environment (rlgpu). When i try to run python examples (joint_monkey.py) i get this error:
(rlgpu) student@lr-mimi:~/Documents/Ana_Udir/IsaacGym_Preview_3_Package/isaacgym/python/examples$ python joint_monkey.py
Importing module ‘gym_37’ (/home/student/Documents/Ana_Udir/IsaacGym_Preview_3_Package/isaacgym/python/isaacgym/_bindings/linux-x86_64/gym_37.so)

Can anyone please help?
