mxnet.ndarray.mean(data=None, axis=_Null, keepdims=_Null, exclude=_Null, out=None, name=None, **kwargs)

Computes the mean of array elements over given axes.

Defined in src/operator/tensor/

  • data (NDArray) – The input

  • axis (Shape or None, optional, default=None) –

    The axis or axes along which to perform the reduction.

    The default, axis=(), will compute over all elements into a scalar array with shape (1,).

    If axis is int, a reduction is performed on a particular axis.

    If axis is a tuple of ints, a reduction is performed on all the axes specified in the tuple.

    If exclude is true, reduction will be performed on the axes that are NOT in axis instead.

    Negative values means indexing from right to left.

  • keepdims (boolean, optional, default=0) – If this is set to True, the reduced axes are left in the result as dimension with size one.

  • exclude (boolean, optional, default=0) – Whether to perform reduction on axis that are NOT in axis instead.

  • out (NDArray, optional) – The output NDArray to hold the result.


out – The output of this function.

Return type

NDArray or list of NDArrays
