I’ve got this error after running the code written with PyTorch on two GPUs:
RuntimeError: NCCL error in: …/torch/csrc/distributed/c10d/ProcessGroupNCCL.cpp:47, unhandled cuda error, NCCL version 21.0.3
ncclUnhandledCudaError: Call to CUDA function failed.
torch version: ‘1.11.0+cu102’
cuda version: 11.4 driver: 470.63.01
Could you please tell if this error happened because of incompatibility of cuda and torch version? and how can I fix it?
Thanks!
Could you rerun your script with NCCL_DEBUG=INFO and post the log here, please?
Here is the log:

This output doesn’t show any NCCL logs but just the PyTorch stacktrace, so make sure to export this env variable before rerunning your script.
I think this is NCCL logs:

Yes, these are the NCL logs, but they also don’t show any previous error besides:

Thanks for the updated logs.
The error is raised by:
The current PyTorch install supports CUDA capabilities sm_37 sm_50 sm_60 sm_70.
If you want to use the NVIDIA A100-PCIE-40GB GPU with PyTorch, please check the instructions at Start Locally | PyTorch
and NCCL just reraises it.
Your A100 GPU needs CUDA>=11.0 so install the binaries with the 11.3 or 11.6 runtime.
Hi @ptrblck , I am stuck for last few days on this error below when running the script using torch.distributed.launch python3.8 -m torch.distributed.launch \ --nnodes=1 \ --node_rank=0 \ --nproc_per_node=2 \ train_stdec.py.
Sorry for my inability to post question properly. The error looks like this.

This error:
CUDA error: the launch timed out and was terminated
is raised if the OS kills the kernel.
This is usually the case if the GPU is used for video output (e.g. X window) and the OS wants to avoid a lagging video output.
As a workaround you could kill the X server and rerun the workload in a terminal only to see if it would be working.
