(1) ncclUnhandledCudaError and ncclSystemError indicate that a call NCCL made to an external component failed, which caused the NCCL operation to fail. The error message should explain which component the user should look at and try to fix, potentially with the help of the administrators of ...
During the execution of the HuggingFace Trainer.train(), I encountered the RuntimeError: NCCL Error 1: unhandled cuda error multiple times. This error happens occasionally at the last step of each epoch. I also wrapped the training process in a ray task by @ray.remote(num_cpus=8, num_gpu...
Hi, I am trying to use NCCL2 train my net using caffe. And I encounter such error which I cannot solve it by myself. My set up is 2 machine with 8 Tesla P40 GPUs each. And my shell code is: mpiexec --allow-run-as-root -machinefile hosts ...
