"can't set attribute" when trying to make an environment

I tried to run the example notebook which is in the documentation of the repo, but first I encountered the error Pybulletgym is not defined. after installing pybulletgym again there was the error can't set attribute. here is the screenshot of the code.

Example Notebook

Can you please provide a Google Colab notebook showcasing a basic example.

Uniform random agent not moving in AntGather environment

I tried the example code provided in the README. the agent is not making any move from the initial position it was dropped, except it jitters its body a little.

import hrl_pybullet_envs
import gym
import numpy as np

env = gym.make('AntGatherBulletEnv-v0')
env.render()
ob = env.reset()
tot_rew = 0

for i in range(1000):
  # Take random actions
  ob, rew, done, _ = env.step(np.random.uniform(-1, 1, env.action_space.shape))
  tot_rew += rew

  if done: break

print(f'Achieved total reward of: {tot_rew}')
