I'm using detectron2 wit pytorch 1.10 and cuda 11.8 on a HPC machine. Using one node works well, but using more than one node I get:
File "**/.conda/envs/detectron2_conda/lib/python3.8/site-packages/torch/distributed/distributed_c10d.py", line 2709, in barrier work = default_pg.barrier(opts=opts) RuntimeError: NCCL error in: /opt/conda/conda-bld/pytorch_1640811806235/work/torch/csrc/distributed/c10d/ProcessGroupNCCL.cpp:957, unhandled system error, NCCL version 21.0.3 ncclSystemError: System call (socket, malloc, munmap, etc) failed.
I suspect detectron2 is incompatible with such NCCL version. Have you ever seen such error? Thanks.
