whatNumIsThis("C:/Users/p.de.falco/Desktop/images/test.png")

嗨，这是更大代码的一部分。它给了我这个错误：

Traceback (most recent call last):
  File "C:/Users/p.de.falco/PycharmProjects/test_1/detect3.py", line 30, in <module>
    whatNumIsThis('C:/Users/p.de.falco/Desktop/images/test.png')
  File "C:/Users/p.de.falco/PycharmProjects/test_1/detect3.py", line 3, in whatNumIsThis
    loadExamps = open('C:/Users/p.de.falco/Desktop/images/numArEx.txt', 'r').read()
IOError: [Errno 2] No such file or directory: 'C:/Users/p.de.falco/Desktop/images/numArEx.txt'

我将路径与我在代码中放置的其他路径相同，但是在这种情况下，它无法找到文件。我正在使用pycharm和anaconda3，有人知道如何解决此问题吗？谢谢你！

看起来您的文件在给定路径上不存在
您可以通过以下方式在打开文件之前验证其中一个文件是否存在：

import os.path
os.path.exists('C:/Users/p.de.falco/Desktop/images/numArEx.txt')

如果文件存在则返回True
希望这可以帮助！
干杯！
