I’m attempting to run the imitation learning library [Atari-Reset](https://github.com/openai/atari-reset) from openai on Github.

This repo requires installation of [Horovod on GPU](https://github.com/horovod/horovod/blob/master/docs/gpus.md) and Cuda-aware Open MPI. Would it be possible for you to write a installation guide for this stack? It gets confusing when Open MPI asks for the locations of the ucx-cuda and cuda locations (See ‘Building CUDA-aware Open MPI’).

I have been able to install the libraries with CPU support, but I want to get the GPU compute power of my Lambda Quad.
