When i try to put this code:

• python3 -m pybullet_envs.deep_mimic.testrl --arg_file run_humanoid3d_backflip_args.txt

AttributeError: type object 'Callable' has no attribute '_abc_registry'

please let me know how to resolve this. Many thanks!

For future references, pip uninstall typing seems to solve the issue. It must be some sort of conflict between pybullet and typing.
