SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

When reading pickle file, the above error is reported

Pickle file path is copied directly, no problem

Solution

The picture above shows the error message and the file path

It seems that there is no problem, but the problem still appears in the path

Because in Windows system, the “\” in the path will be escaped

For example, if you configure a path: D:// source <XXX/a.txt, the system will escape the “ ” to a tab key, so that the file path is wrong

The correct path should be:

The first way to write: D:\\source\\\t\\xxx\\\a.txt 

Second way to write: r "D:\source\t\xxx\\a.txt"

The third way to write: D:/source/t/xxx\a.txt # Path writing in Linux

the third writing method is recommended because it is common in windows and Linux
