mindspore.hal.reset_peak_memory_stats

mindspore.hal.reset_peak_memory_stats(device_target=None)[source]

Reset the "peak" stats tracked by memory manager.

Note

If device_target is not specified, get the device capability of the current backend set by context.

Parameters: device_target (str, optional) – The device name of backend, should be one of "CPU", "GPU" and "Ascend". Default value: None.

Examples

>>> import mindspore as ms
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> a = Tensor(np.ones([1, 2]), ms.float32)
>>> b = Tensor(np.ones([1, 2]), ms.float32)
>>> c = ops.add(a, b).asnumpy()
>>> print(ms.hal.max_memory_reserved())
