Description

Hi All

Is it possible to run MeltingPot with vectorised environments? I am using CleanRL + Shimmy to run MeltingPot but when I try to use `concat_vec_envs_v1` I get error: 'TypeError: cannot pickle `dmlab2d.dmlab2d_pybind.Lab2d object`. Is there any other way? Any advice would be appreciated.
