I compiled mxnet on ubuntu18, and got libmxnet.so.
Then tested it by the example of my model, but got error when runing program on the line of MXPredSetInput(pred_hnd, "data", image_data.data(), static_cast<mx_uint>(image_size));,
the error is:
[17:21:39] …/src/nnvm/legacy_json_util.cc:209: Loading symbol saved by previous version v1.4.1. Attempting to upgrade…
[17:21:39] …/src/nnvm/legacy_json_util.cc:217: Symbol successfully upgraded!
