    """
    Given 1-D `indices` tensor, gather elements at `i` in `indices` from all the
    blobs in `record`. If a blob is a values blob of a list, all the elements
    included by the list's lengths blob are gathered. For example,

Input:
        indices = [0, 2]
        record:a = [[0, 1], [2, 3], [4, 5], [6, 7]]
        record:b:lengths = [0, 1, 2, 3]
        record:b:items = [0, 1, 2, 3, 4, 5]

Output:
        a = [[0, 1], [4, 5]]
        b:lengths = [0, 2]
        b:items = [1, 2]

This supports nested list.
