Describe the Bug

I've partially identified the cause and have been able to proceed with the execution. However, I'd like to inquire about more detailed investigations and better solutions. Below is the error message I encountered during execution:

❯ ./labelme2coco.py val val4coco --labels class.txt 
Creating dataset: val4coco

ValueError: y1 must be greater than or equal to y0

It appears that this issue is caused by the addition of assertions in a recent version update of Pillow. In my environment, Pillow version 10.3.0 did not work, but downgrading to version 9.1 resolved the issue and the behavior was as expected.

❯ pip install pillow 
Requirement already satisfied: pillow in /home/watanabe/work/YOLOX/pyenv/lib/python3.12/site-packages (10.3.0)

pip install pillow==9.1
