pyqt+Python两个类之间传值

Question

class Ui_MainWindow的某个代码段

    def massage(self):
        print("按了啊")
        dir_choose, filetype = QFileDialog.getOpenFileName(self.model, "选取文件", "./",                                                  "All Files (*);;Excel Files (*.xls)")
        # 起始路径
        if dir_choose == "":
            print("\n取消选择")
            return
        print("\n你选择的文件夹为:")
        print(dir_choose)
        self.model.setText(dir_choose)
        adaboost = Adaboosting()
        result=adaboost.demo(dir_choose)
        self.text1.setText("训练完成")
        self.model_result.setText(result)

然后调用另一个类class Adaboosting的方法

    def demo(result):
        print("已进入到了内部函数")
        # result="text1.txt"
        from my_adaboosting_SVM_ROC import loadDataSet
        dataArr, LabelArr = loadDataSet(result)
        from my_adaboosting_SVM_ROC import adaBoostTrainDS
        weakClassArr, aggClassEst = adaBoostTrainDS(dataArr, LabelArr)
        from my_adaboosting_SVM_ROC import adaClassify
        predictions = adaClassify(dataArr, weakClassArr)
        errArr = np.mat(np.ones((len(dataArr), 1)))
        number=float(errArr[predictions != np.mat(LabelArr).T].sum() / len(dataArr) * 100)
        print('训练集的错误率:%.3f%%' % float(errArr[predictions != np.mat(LabelArr).T].sum() / len(dataArr) * 100))
        return number

但是这两类之间传值没实现，报错如下
Process finished with exit code -1073740791 (0xC0000409)
