 [deepspeed] test on one node 2 gpus max
Deepspeed devs, who will be running our deepspeed tests as part of their tests, discovered that we had an unbound number of nodes and gpus in the tests so it was firing on multiple nodes and many gpus, so wasn't quite ready for it. So fixing it.
ok, it's all working in the Deepspeed team's test suite - yay!
