chainerx.mean(a, axis=None, keepdims=False)

Compute the arithmetic mean along the specified axis.

Returns the average of the array elements. The average is taken over the flattened array by default, otherwise over the specified axis.

  • a (ndarray) – Array to take the mean of.

  • axis (None or int or tuple of ints) – Along which axis or axes to compute

  • default. (the mean. The flattened array is used by) –

  • keepdims (bool) – If this is set to True, the axes which are reduced are

  • option (left in the result as dimensions with size one. With this) –

:param : :param the result will broadcast correctly against the input array.:


The mean of a, along the axis or axes if specified.
