When I run ./tecnets_corl_results.sh sim_reach,error appear：

Traceback (most recent call last): File "/home/user/gym-mil/gym/core.py", line 203, in del self.close() File "/home/user/gym-mil/gym/core.py", line 164, in close self.render(close=True) File "/home/user/gym-mil/gym/core.py", line 150, in render return self._render(mode=mode, close=close) File "/home/user/gym-mil/gym/envs/mujoco/mujoco_env.py", line 104, in _render if self.viewer is not None: AttributeError: 'ReacherMILEnv' object has no attribute 'viewer'

What makes this error? Hope some tips,thanks.
