label generation problem

[Hj]

Hi, when I use your code to auto-generate labels, the label pairings are empty. The image is the details. And the output file is also empty. But I still have not found the wrong place.

Hi,

Do you mind providing the environment you are using? Maybe it is an environment mismatch.
