Bug when init VariantGenerator

[JunningHuang]

Hi, I try to run the code. Last day, I success. But today I meet a strange problem.
I don't modify any code, just use setup_mujoco.sh script from
to setup the mujoco env for running cluster_trpo_cheetah.py:
For bug information see:

It seems that the VG class init with 4 arguments but default init is 2. But I check the class VariantGenerator, it's init with no arguments. So with this bug information I can't locate where the problem is. Have you ever meet this problem.

Did you make any changes to cluster_trpo_cheetah.py?

@cbfinn I am facing the same problem. I didn't make any change in the algorithm.
