torch.xpu.memory.memory_allocated

torch.xpu.memory.memory_allocated(device=None) [source]

Return the current GPU memory occupied by tensors in bytes for a given device.

Parameters

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).

Return type

int

Note

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.
