KeyError: 'coco_url'

[Siddhi Jain]

I am trying to convert dataset from coco to voc format using anno_coco2voc.py file but got this KeyError: 'coco_url'

billion@billion-Inspiron-3542:~/Dataset_to_VOC_converter$ python3 anno_coco2voc.py --anno_file /home/billion/Desktop/Siddhi/document_edge_detection_dataset/earlier_training/testing/test.json \

                     --type instance \
                     --output_dir /home/billion/Desktop/Siddhi/document_edge_detection_dataset/earlier_training/annotations

Traceback (most recent call last):
