Dose create_compound support string or vector?

  std::vector<Test> dims{{1, "3", vector<int>{0, 1}},
                         {2, "4", vector<int>{2, 3}}};
  auto dataset = file.createDataSet(DATASET_NAME, dims);

  auto g1 = file.createGroup("group1");
  g1.createAttribute(DATASET_NAME, dims);
}

The second error confuses me, How can I achieve my purpose? thanks

Hi@xuedj , I have encountered the same problem as you. How did you solve it?
