Bug

Hi everybody. I am training a custom dataset with the yoloV9 model and the following error message appears. Does someone have a similar problem or know how to fix this exception ? When I start the train.py the following exception (Exception in thread Thread-14 (plot_images)) is raising up, but it does not interrupt the program. Here is the full code.
