You should use the version of MSVC that is used to build the version of Python from python.org - MSVC 2015 in the case of Python v3.6.

Alternatively, those symbols are defined in mincore.lib so you could try adding them to the qmake page in pyqtdeploy. Something like...

win32 {
    LIBS += -lmincore
}
