Hello People,

I am getting the following error when I run . scripts/local_run_exp.sh ga configurations/frostbite_ga.json, which is the GA experiment

Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main

    eval_rews, eval_length = policy.rollout(env)  # eval rollouts don't obey task_data.timestep_limit
ValueError: too many values to unpack (expected 2)

and I managed to fixed it by changing the following code:

from

deep-neuroevolution/es_distributed/ga.py, line 230:

eval_rews, eval_length = policy.rollout(env) # eval rollouts don't obey task_data.timestep_limit

to:

deep-neuroevolution/es_distributed/ga.py, line 230:

eval_rews, eval_length, _ = policy.rollout(env) # eval rollouts don't obey task_data.timestep_limit

My environment information: Ubuntu 18.04 x64 Python 3.6.8 tensorflow 1.13.1 Click 7.0 atari-py 0.1.15 numpy 1.16.3 gym 0.12.1 baselines 0.1.5

Thanks
