Overview Python v0.3.0 is_nccl_available¶ dragon.distributed.is_nccl_available()[source]¶ ReturnwhethertheNCCLbackendisavailable. Returns: bool–TrueifavailableotherwiseFalse.
cuda.is_available()) 如果输出为False,则说明PyTorch没有检测到GPU。在这种情况下,您需要检查PyTorch的安装是否正确,或者尝试重新安装PyTorch。如果您确定PyTorch已经正确检测到了GPU,但仍然遇到“RuntimeError: ProcessGroupNCCL is only supported with GPUs, no GPUs found”错误,那么问题可能在于您的代码中使用了不...
这通常是通过在代码中检查torch.cuda.is_available()来实现的,如上例所示。此外,如果您在分布式训练环境中使用PyTorch的DistributedDataParallel(DDP)或torch.nn.parallel.DistributedDataParallel,并且在没有GPU的情况下尝试使用NCCL作为后端,您应该考虑改用Gloo后端或其他适用于CPU的后端。 在DDP中,您可以通过设置process_...
