Examples

Shape origin_shape({3, 256, 256}); // Set the original shape to 3 x 256 x 256.
Shape out_shape;
ExpandDimsType type1("1000");
ExpandDimsType type2("10000");
ExpandDimsType type3("1001");
auto ret = type1.Expand(origin_shape, out_shape); // ret = ge::GRAPH_SUCCESS, out_shape = 1,3,256,256
ret = type2.Expand(origin_shape, out_shape); // ret = ge::GRAPH_FAILED
ret = type3.Expand(origin_shape, out_shape); // ret = ge::GRAPH_SUCCESS, out_shape = 1,3,256,1,256
