Take this link as a reference.

To my problem, use otool -L hello.so:

hello.so:
    hello.so (compatibility version 0.0.0, current version 0.0.0)
    libboost_python.dylib (compatibility version 0.0.0, current version 0.0.0)
    /System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.10)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.1.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1225.1.1)

you can see that libboost_python.dylib is not point to the really exist path.

so use this command:

install_name_tool -change libboost_python.dylib /usr/local/lib/libboost_python.dylib hello.so 

and run otool -L hello.so again:

hello.so:
    hello.so (compatibility version 0.0.0, current version 0.0.0)
    /usr/local/lib/libboost_python.dylib (compatibility version 0.0.0, current version 0.0.0)
    /System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.10)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.1.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1225.1.1)

and finally run python test.py, I get the result.
