pyautogui 无法找到图像异常，即使它存在

Question

我长期使用 Pyautogui 库进行图像跟踪。 我不知道为什么，但我刚买了一台新笔记本电脑，但它根本不适合我。 即使图像存在，它也会抛出“找不到图像”错误。 我可以保证图像路径也是绝对正确的。 即使我尝试过 就像我下面给出的简单程序，但它仍然显示错误。

有人可以帮忙吗？ 真的很欣赏它。 谢谢！

from pyautogui import *

a = locateOnScreen("E:/Mark 7/Test.png")

print(a)

if not (a == None):

    print("Got Image")

if(a==None):

    print("Oops!")

当我尝试此操作时，我收到此错误

Traceback (most recent call last):

pyscreeze.ImageNotFoundException: Could not locate the image.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    a = locateOnScreen("E:\\Mark 7\\Test.png")

    raise ImageNotFoundException  # Raise PyAutoGUI's ImageNotFoundException.
pyautogui.ImageNotFoundException

Answer 1

尝试使用置信度参数。像这样。 pyautogui.locateOnScreen("E:/Mark 7/Test.png",confidence=0.7)

ImageNotFoundException 实际上并不意味着没有“E:/Mark 7/Test.png”文件。

我认为，ImageNotFoundException 意味着在屏幕上找不到与图像匹配的图案。

可以使用try: except:语句正确处理异常。
