ImportError: DLL load failed

[petepetepete88]

Hiya,

I'm using UE version 5.0.3 and when I load up the cart example (with no changes, created from the UE marketplace), MindMaker.exe starts but has this ImportError straight away and closes.

Any ideas or suggestions?

I believed the issue your facing could be the result of the DDPG algorithm requiring OpenMPI as a dependency. You can download openMPI here

you may also require the python dependency which can be installed with conda or pip

conda install mpi4py

I will upgrading mindmaker to Stable baselines 3 shortly(hopefully in the next week) and this should take care of this issue.
