multiprocess reduce can't pickle local object 'ModifiedSizeEnvFactory'.<locals>.ModifiedSizeEnv #9

When I use Morphological Modifications of the Mujoco agent, such as HalfCheetahBigFoot in multiprocess, I get the 'can't pickle local object 'ModifiedSizeEnvFactory'..ModifiedSizeEnv' screenshot 2019-02-28 15 28 25 by the way, When I do not create an agent(HalfCheetahBigFoot) in a multiprocess way, It's OK.

Did you figure out the issue here? I'm not sure what the rest of the code looks like for multiprocessing so it's a bit hard to figure out what's going on.
