from mindspore import Tensor
import mindspore.ops as ops
import numpy as np
from mindspore import context
#context.set_context(mode=context.PYNATIVE_MODE, device_target='GPU')
context.set_context(mode=context.GRAPH_MODE, device_target='GPU')
input_x = Tensor(np.array([[1.0], [2.0], [4.0]]), mindspore.float32)
input_y = 3
_pow = ops.Pow()
_mean = ops.ReduceMean()
#out = _pow(input_x, input_y)
out = _mean(input_x)
print(out)
print(out.dtype) 運作結果：
如果把資料的類型該為float64， 則報錯：
input_x = Tensor(np.array([[1.0], [2.0], [4.0]]), mindspore.float64) 代碼：
