Request: Support for vectorised environments

[AsadJeewa]

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.

I need to train faster as I have limited compute walltime and the easiest way is vectorised environments. Any other methods for optimisation?

Maybe try raising this on the issues page for the underlying engine: dmlab2d

I have done so but have received no response
