1. Write the setup.py file:
the content of the setup.py file as follows:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
extensions = [
Extension("UIBox", ["UIBox.py"],
include_dirs=["../include"],
libraries=["../lib/cv2/cv2.cpython-36m-aarch64-linux-gnu.so",
"../lib/dlib-19.17.0-py3.6-linux-aarch64.egg/dlib.cpython-36m-aarch64-linux-gnu.so"],
library_dirs=["../lib/cv2",
"../lib/dlib-19.17.0-py3.6-linux-aarch64.egg"]),
Extension("UIShow", ["UIShow.py"],
include_dirs=["../include"],
libraries=["../lib/cv2/cv2.cpython-36m-aarch64-linux-gnu.so",
"../lib/dlib-19.17.0-py3.6-linux-aarch64.egg/dlib.cpython-36m-aarch64-linux-gnu.so"],
library_dirs=["../lib/cv2",
"../lib/dlib-19.17.0-py3.6-linux-aarch64.egg"]),
……
]
setup(ext_modules=cythonize(extensions))
Write as many Extensions as there are py files included in the entire project, and set other library paths that need to be called in include_dirs, libraries, library_dirs.
2. Compile the so file and execute the following command:
python setup.py build_ext
3. Call the so file
and add the following content to the called py file to
import sys
sys.path.append('../lib.linux-aarch64-3.6') #Load the so file (the input parameter is so file path)
from libSupernode import libSupernode #import related classes in so file
