The error seems to come from NCCL not being able to use shared memory:
NCCL WARN Call to posix_fallocate failed : No space left on device
[...]
NCCL WARN Error while creating shared memory segment nccl-shm-recv-ea821c4e67e70b28-0-2-0 (size 9637888)

so make sure your machine has enough shared memory and if you are using a docker container, use the --ipc=host argument (or specify the shared memory usage manually).
