Describe the bug

I cannot make a gym environment anymore. I get an error stating

Traceback (most recent call last):
  File "test.py", line 26, in <module>
    env = gym.make('PandaReach-v2', render=True)
  File "/home/jakob/anaconda3/envs/panda/lib/python3.7/site-packages/gym/envs/registration.py", line 235, in make
    return registry.make(id, **kwargs)
  File "/home/jakob/anaconda3/envs/panda/lib/python3.7/site-packages/gym/envs/registration.py", line 129, in make
    env = spec.make(**kwargs)
  File "/home/jakob/anaconda3/envs/panda/lib/python3.7/site-packages/gym/envs/registration.py", line 90, in make
    env = cls(**_kwargs)
  File "/home/jakob/Promotion/code/panda-gym/panda_gym/envs/panda_tasks/panda_reach.py", line 20, in __init__
    sim = PyBullet(render=render)
  File "/home/jakob/Promotion/code/panda-gym/panda_gym/pybullet.py", line 34, in __init__
    self.connection_mode = p.GUI if render else p.DIRECT
AttributeError: module 'pybullet' has no attribute 'GUI'

To Reproduce

Starting on a clear plate

conda create -n panda python=3.7
conda activate panda
~/panda-gym$ pip install -e .

and running the quick start code

import gym
import panda_gym

env = gym.make('PandaReach-v2', render=True)

leads to the aforementioned error. I also tried python 3.8

System

• OS: Ubuntu 20.04
• Python version (python --version): 3.7, 3.8
• Package version (pip list | grep panda-gym): panda-gym 2.0.0 | pybullet 3.2.1

Hello,

Thank you for reporting this bug.

Can you try to execute the same python code from ~ ?

cd  ~
python <PATH_TO_YOUR_CODE>/your_code.py

Intuition: After checking, the latest version of pybullet still has the GUI attribute. So I think this bug comes from the fact that you are running this script from a panda-gym/panda_gym At this location pybullet is referring to pybullet.py (a panda-gym helper file) and not the pybullet module.
