【Pyautogui自动准备jupyter】附上报错合集，已解决

刚认识了pyautogui，浅浅写一段自动准备jupyter的程序

import pyautogui 
#import pyperclip
import time
 
def open_jupyter():
    print('Opening jupyter...')
    time.sleep(1)
    
    try:
        location = pyautogui.locateOnScreen(r"D:\STEFANOS\python\tools\auto\icons\jupyter.png",confidence=0.8) 
        print(location)
        pyautogui.click(location)
    except pyautogui.ImageNotFoundException:
        print("Sorry I cannot locate Jupyter")

    time.sleep(3)
    
def new():
    print('newing...')
    time.sleep(1)
    
    try:
        location = pyautogui.locateOnScreen(r"D:\STEFANOS\python\tools\auto\icons\new.png",confidence=0.8) 
        print(location)
        pyautogui.click(location)
    except pyautogui.ImageNotFoundException:
        print("Sorry I cannot locate 'new'")

    time.sleep(1)

def python3():
    print('newing python3...')
    time.sleep(1)
    
    try:
        location = pyautogui.locateOnScreen(r"D:\STEFANOS\python\tools\auto\icons\python3.png",confidence=0.8) 
        print(location)
        pyautogui.click(  )
    except pyautogui.ImageNotFoundException:
        print("Sorry I cannot locate 'python3'")

    time.sleep(1)

open_jupyter()
new()
python3()

报错：

第一类：unicode编码问题

OSError: Failed to read D:\STEFANOS\python oolsuto\icons\jupyter.png because file is missing, has improper permissions, or is an unsupported or invalid format

[ WARN:[email protected]] global loadsave.cpp:241 cv::findDecoder imread_(‘D:\STEFANOS\python oolsuto\icons\jupyter.png’): can’t open/read file: check file path/integrity

SyntaxError: (unicode error) ‘unicodeescape’ codec can’t decode bytes in position 232-233: truncated \UXXXXXXXX escape

写在前面：复制路径快捷键Ctrl+Shift+C

方法1：在路径前加r

location = pyautogui.locateOnScreen(r"D:\STEFANOS\python\tools\auto\icons\jupyter.png")

方法2：写成双斜杠\\

location = pyautogui.locateOnScreen("D:\\STEFANOS\\python\\tools\\auto\\icons\\jupyter.png")

方法3：改成/

location = pyautogui.locateOnScreen("D:/STEFANOS/python/tools/auto/icons/jupyter.png")

第二类：图像识别问题

raise ImageNotFoundException # Raise PyAutoGUI’s ImageNotFoundException.
ImageNotFoundException

可以降低图片‘信任度’，但建议在confidence=0.8这样，
否则，比如会把jupyter识别成blender（无语了

第三类：写着写着就不见了的问题

python:ocal variable ‘xxx’ referenced before assignment

KeyboardInterrupt
