mindspore.runtime.memory_stats

查看源文件
mindspore.runtime.memory_stats()[源代码]

返回从内存池查询到的状态信息。

说明

  • 对于 CPU 后端，固定返回数据为空的字典。

返回：

dict，查询到的内存信息。

样例：

>>> import mindspore as ms
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> ms.set_device("Ascend", 0)
>>> a = Tensor(np.ones([1, 2]), ms.float32)
>>> b = Tensor(np.ones([1, 2]), ms.float32)
>>> c = ops.add(a, b).asnumpy()
>>> print(ms.runtime.memory_stats())
