python numpy ndarray元素均值 [英] python numpy ndarray element-wise mean

问题描述

我想计算numpy ndarray的逐元素平均值.

I'd like to calculate element-wise average of numpy ndarray.

In [56]: a = np.array([10, 20, 30])

In [57]: b = np.array([30, 20, 20])

In [58]: c = np.array([50, 20, 40])

我想要什么:

[30, 20, 30]

除了矢量求和和除法之外，该操作是否有任何内置函数?

Is there any in-built function for this operation, other than vectorized sum and dividing?

推荐答案

您可以直接使用np.mean:

>>> np.mean([a, b, c], axis=0)
array([ 30.,  20.,  30.])
