Using oneflow SD with graph save/load, updating oneflow version got error: user_op_conf.cpp:87] Check failed: attr.get() != nullptr attr_name: query_head_size

oneflow-0.9.1.dev20230216+cu117 works, updating to oneflow-0.9.1.dev20230312+cu117 and oneflow-0.9.1.dev20230309+cu117 will raise Error

It turns out that the graphs are saved with oneflow-0.9.1.dev20230216+cu117 , but load with newer versions of oneflow.

The newer versions of oneflow has updated some Operator Config, and Operater Config is part of the saved Graph.

So the newer versions oneflow cannot load the old saved graph. Please compile and save graphs with the new version oneflow, then you can load the new graph.
