现在可以了。我用的PyTorch2.1.0+cu121,4060的显卡有8G显存,16G的共享显存,可以直接创建一个占用16...

A GPU-Ready Tensor Library If you use NumPy, then you have used Tensors (a.k.a. ndarray). PyTorch provides Tensors that can live either on the CPU or the GPU and accelerates the computation by a huge amount. We provide a wide variety of tensor routines to accelerate and fit your sci...
然而当我们希望分配存储给 GPU,我们最终会使用如 cudaMallocHost() 那样的 CUDA 分配器,我们可以在下面的 THCudaHostAllocator malloc 函数中看到这一点。static void *THCudaHostAllocator_malloc(void* ctx, ptrdiff_t size) {void* ptr; if (size < 0) THError("Invalid memory size: %ld", size); ...
I expect similar it/s to before I installed some OS and driver updates and low usage of the GPU BUS and shared memory. Actual Behavior However, instead the GPU utilization is pinned to 100%, BUS usage spikes much higher than normal, GPU temps stay low, shared GPU memory spikes from it...

Note: DIGITS uses shared memory to share data between processes. For example, if you use Torch multiprocessing for multi-threaded data loaders, the default shared memory segment size that the container runs with may not be enough. Therefore, you should increase the shared memory size by issuing...
use_env:使用 used_env 后,pytorch 会把当前进程所使用的 local_rank 放到环境变量中,而不会放在args.local_rank 中。目前,官方现在已经建议废弃使用 torch.distributed.launch,而是建议使用 torchrun。在 torchrun 中,--use_env 这个参数被废弃了并作为默认设置在 torchrun 中,从而强制要求用户从环境变量的 LOAC...
要启用PyTorch distributed, 需要在源码编译的时候设置USE_DISTRIBUTED=1。目前在Linux系统上编译的时候,默认就是USE_DISTRIBUTED=1,因此默认就会编译distributed模块;而在MacOS上默认是0(你需要手动开启,在PyTorch 1.3的时候才添加了对macOS的支持,使用Gloo backend)。那么Windows系统呢?Windows不支持distributed(不过没什么...
