DTSED:

extraFilesMap


Please take a look at this
‘https://github.com/pytorch/pytorch/blob/22401b850b2010119d3f674f495b7c2b2dfb710b/test/cpp/jit/test_save_load.cpp#L16 32’
It seems to me that the extra_files can store string only.
If you want more info, please change the category to ‘jit’, jit people can provide more info.
