Hi

Importing the Ingenuity task/environment outside the IsaacGymEnvs/isaacgymenvs folder produces the following error:

Problem: The path to the assets is relative only to the isaacgymenvs python package.

Steps to reproduce:

1. Open python (interactive terminal) in any folder except IsaacGymEnvs/isaacgymenvs
2. Execute the following code

   import isaacgym
   import isaacgymenvs
   env = isaacgymenvs.make(seed=42, 
                       task="Ingenuity", 
                       num_envs=4096, 
                       sim_device="cuda:0",
                       rl_device="cuda:0",
                       graphics_device_id=0,
                       headless=False)

Hi, have you fixed this error? I met similar errors as yours.

Hi @dulucas

Nop...

Each time I want to play with this task, I need to copy the main script to the IsaacGymEnvs/isaacgymenvs folder and run it from there
