when i try to run v0.14.0 from source code, it raise ImportError.

[KingArtherTT]

I clone the source code from github, then i want to run the openpifpaf/src/openpifpaf/predict.py file.And it raise error.I tracked down the issue and found that the error came from cpp_extension.register_ops()。

extfinder = importlib.machinery.FileFinder(lib_dir, loader_details)
ext_specs = extfinder.find_spec("_cpp")
if ext_specs is None:
raise ImportError

It needs some openpifpaf._cpp files where i found in setup.py.
I want to run from the source code, and i do not know how to build this openpifpaf._cpp file,please help!!

I already fixed it.
you need run the following command and manually specify the path of _cpp.so file .
1. python setup.py build
2. python setup.py install
3. check the _cpp.so file path and remember it.
4. set the code in cpp_extension.py file
5. lib_dir = 'the path of your _cpp.so file'
