torch.xpu.memory.max_memory_allocated

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

返回给定设备上张量占用的最大 GPU 内存（以字节为单位）。

By default, this returns the peak allocated memory since the beginning of this program. reset_peak_memory_stats() can be used to reset the starting point in tracking this metric. For example, these two functions can measure the peak allocated memory usage of each iteration in a training loop.

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
