sparse.nansum(x, axis=None, keepdims=False, dtype=None, out=None)[source]

Performs a NaN skipping sum operation along the given axes. Uses all axes by default.

Parameters:
  • x (SparseArray) – The array to perform the reduction on.

  • axis (Union[int, Iterable[int]], optional) – The axes along which to sum. Uses all axes by default.

  • keepdims (bool, optional) – Whether or not to keep the dimensions of the original array.

  • dtype (numpy.dtype) – The data type of the output array.

Returns:

The reduced output sparse array.
