How to use the ramp-engine.rampbkd.config.get_deployment_path function in ramp-engine

def path(self):
        return os.path.join(
            config.get_deployment_path(),
            'submissions',
            'submission_' + '{0:09d}'.format(self.id))

def get_train_data(self):
        path = os.path.join(config.get_deployment_path(),
                            'ramp-data',
                            self.name)
        return self.module.get_train_data(path=path)

def get_test_data(self):
        path = os.path.join(config.get_deployment_path(),
                            'ramp-data',
                            self.name)
        return self.module.get_test_data(path=path)

def module(self):
        return imp.load_source(
            '', os.path.join(config.get_deployment_path(),
                             'ramp-kits',
                             self.name,
                             'problem.py'))
