Ask questionsa retrained and saved jit module could not be reload.

I'm try to retain a JIT module from pytorch using c++ based on Libtorch libtorch-win-shared-with-deps-1.3.0 _cpu, and save retrained module for next usage. the save and reload process will be like the following , but get erro while try reload.

		torch::serialize::OutputArchive output_archive;
		auto presavedModule = torch::jit::load("D:/localshare/data/model/model.pt");
		presavedModule.save("D:/localshare/data/model/testmodel.pt");
		auto savedModule = torch::jit::load("D:/localshare/data/model/testmodel.pt");
		savedModule.dump(true, true, true);

reported error:

Are you able to share the model.pt you are using to get this error?

useful!
