    Args:
      tensor: A Tensor. Must be one of the following types:
      uint8, int8, int16, int32, int64, float32, bool Up to 8-D.

      axis: A Tensor. Must be one of the following types: int32, int64.
      with only 1 element which is the axis index.
      TODO: Add support for multiple elements.
