I download the Isaac Gym Preview 4 release from the website, then follow the installation instructions in the documentation using a conda environment to simplify set up. The Isaac Gym works on my system well when running one of the examples from the python/examples directory. Then I installed the Isaacgymenvs from the website, But when I created the environment using the code in repo:
“”"
import isaacgym
import isaacgymenvs
import torch
num_envs = 2000
envs = isaacgymenvs.make(
seed=0,
task=“Ant”,
num_envs=num_envs,
sim_device=“cuda:0”,
rl_device=“cuda:0”,
)
print(“Observation space is”, envs.observation_space)
print(“Action space is”, envs.action_space)
obs = envs.reset()
for _ in range(20):
random_actions = 2.0 * torch.rand((num_envs,) + envs.action_space.shape, device = ‘cuda:0’) - 1.0
envs.step(random_actions)
“”"
the error came as following:
