   How to pass a lot of cv:: Mat to MXDataIter ?
   ``C++
   
       auto val_iter = MXDataIter("ImageRecordIter")
               .SetParam("data_shape", Shape(3, image_size, image_size))
               .SetParam("batch_size", batch_size)
               .SetParam("shuffle", 1)
               .SetParam("flat", 1)
               .SetParam("ctx", "cpu")
               .CreateDataIter();
   
       int count = 0;
       Accuracy acc;
       val_iter.Reset();
       while (val_iter.Next()) {
           auto data_batch = val_iter.GetDataBatch();
           data_batch.data.CopyTo(&args_map["data"]);
           NDArray::WaitAll();
           exec->Forward(false);
           acc.Update(data_batch.label, exec->outputs[0]);
       }
   
       delete exec;
       MXNotifyShutdown();
   
       return 0;
