(self, index)
Extract a subset view of the items via slice style indexing
        along each dimension. e.g. A[5:10, :]. Each slice consists of
        start_idx:stop_idx:step_size triplets.  If step_size isn't specified it
        defaults to 1.  If start_idx isn't specified it defaults to 0.  If
        stop_idx isn't specified it defaults to the total number of elements
        along that dimension.  As such a slice value of ':' allows one to
        select all elements along that dimension.

        Arguments:
            index (int, slice, tuple): indices of each dimension's slice.

        Returns:
            Tensor: view of self corresponding to the subset items.

        Raises:
            NotImplementedError: Can't be instantiated directly.
