VS 代码中的 EOF 错误（也不适用于终端）

Question

我在 Manjaro 上使用 vs-code，我在

之后的这个问题中解释了很多问题

我有以下代码

import cv2
from random import randrange
#load data
trained_face_data = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

#Choose image
webcam = cv2.VideoCapture(0)

while True:
    successful_frame_read, frame = webcam.read()

    #convert to greyscale
    greyscaled_img = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)


    #detect faces
    face_coordinates = trained_face_data.detectMultiScale(greyscaled_img)

    #Draw a rectangle around the Face
    for (x, y, w, h) in face_coordinates:
        cv2.rectangle(frame, (x,y), (x+w, y+h), (0, 255, 0, 10)
    
    #Display the image with the faces spotted
    cv2.imshow('Face detector', frame)
    key = cv2.waitKey(1)

    #stop if Q is pressed
    if key==81 or key==113:
    break

webcam.release()
print("code completed")

一开始，我在

处遇到语法错误

  File "Face_detector.py", line 24
    cv2.imshow('Face detector', frame)
    ^
SyntaxError: invalid syntax

我注释掉了这一行，但在下一行出现了同样的错误

  File "Face_detector.py", line 25
    key = cv2.waitKey(1)
    ^
SyntaxError: invalid syntax

所以我继续把每一行注释掉直到最后 现在我收到 EOF 错误

 File "Face_detector.py", line 33

                            ^
SyntaxError: unexpected EOF while parsing

我尝试了 运行 来自终端的脚本，但仍然有完全相同的错误

您在这一行缺少括号：

#Draw a rectangle around the Face
for (x, y, w, h) in face_coordinates:
    cv2.rectangle(frame, (x,y), (x+w, y+h), (0, 255, 0, 10) # <-- Missing parentheses here
