I have created the PASCAL VOC 2007 and 2012 JSON file list. When I ran train.py, I got the errors below: ` 553433881it [19:06, 482647.72it/s]

I have a similar error, I run utils.py, create_data_lists.py, datasets.py, model.py then train.py in order, then during train.py something goes wrong when iterating over the dataloader. Here is my stack trace (parts of file paths removed for privacy):
