Before Change

        // can"t use indices > data length with reduceat`
        trunc = np.searchsorted(indptr, indptr[-1])
        min_or_max.reduceat(mat.data, indptr[:trunc], out=out[:trunc])
        nnz = np.diff(indptr)
        // compare to 0 in non-full rows
        mask = nnz < N
        out[mask] = min_or_max(out[mask], zero)
        // reduceat will have filled empty rows with another data entry
        out[nnz == 0] = zero

After Change

        mat = self.tocsc() if axis == 0 else self.tocsr()
        mat.sum_duplicates()

        major_index, value = mat._minor_reduce(min_or_max)
        min_or_max(value, 0, out=value)

        out = np.zeros(len(mat.indptr) - 1, dtype=self.dtype)
