from win32com.client import Dispatch

# get Femtet control
Femtet = Dispatch('FemtetMacro.Femtet')

# initialize (create temporary foldere and child process)
predictor = Predictor(Femtet)

# predict
id_map: dict = predictor.predict(
    'orig.x_t',
    'var.x_t',
)

# finalize (delete temporary folder and terminate child process)
del predictor
