NameError:vscode中未定义名称“测试”

Question

这是我的密码

image_cnt = 1


while True:

    for  event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()

        if event.type == MOUSEMOTION and iswriting:     
            xcord, ycord = event.pos
            pygame.draw.circle(DISPLAYSURF, WHITE, (xcord,ycord), 4, 0 )

            number_xcord.append(xcord)
            number_ycord.append(ycord)

        if event.type == MOUSEBUTTONDOWN:

            rect_min_x , rect_max_x = max(number_xcord[0]-BOUNDARYINC, 0 ), min(WINDOWSIZEX, number_xcord[-1]+BOUNDARYINC)

            if IMAGESAVE:
                cv2.imwrite("image.png")
                image_cnt +=1

            if PREDICT:

                image = cv2.resize(img_arr, (28,28))
                image = np.pad(image, (10,10), 'constant', constant_values = 0 )
                image = cv2.resize(image, (28,28))/255

                label = str(LABELS[np.argmax(MODEL.predict(image.reshape(1,28,28,1)))])

                textSurface = FONT.render(label, True, RED, WHITE)
                textRecObj = testing.get_rect()
                textRecObj.left , textRecObj.bottom = rect_min_x, rect_max_Y

                DISPLAYSURF.blit(textSurface, textRecObj)

            if event.type == KEYDOWN:
                if event.unicode == "n":
                    DISPLAYSURF.fill(BLACK)


        pygame.display.update()

这就是我一直犯的错误

Traceback (most recent call last):
  File "c:\Users\dell\app.py", line 86, in <module>
    textRecObj = testing.get_rect()
NameError: name 'testing' is not defined

我在大学里修了一门“数据科学”课程，这是一个必修项目 我的讲师只给了我们一周的时间来建立一个手写数字识别模型。我三周前才开始学习这门课，所以我对这门课并不太熟悉。。。 我遵循了这个教程https://www.youtube.com/watch?v=L2cAjgc1-bo&lc=Ugy5PxPjcqMIrl93iNR4AaABAg&ab_channel=edureka%21 你能帮我吗

Answer 1

您从未定义过testing是什么

Answer 2

我相信这条线应该是

textRecObj = textSurface.get_rect()

好像你不小心弄错了
