torch.xpu.memory.memory_allocated

torch.xpu.memory.memory_allocated(device=None)

返回给定设备上张量当前占用的 GPU 内存（以字节为单位）。

参数

device (torch.device or int or str, optional) – selected device. Returns statistic for the current device, given by current_device(), if device is None (default).

返回类型

int

注意

This is likely less than the amount shown in xpu-smi since some unused memory can be held by the caching allocator and some context needs to be created on GPU.
