Data Generation script is running for very long time

[Ashiqur-Rahaman-Khan]

Hi All. I am trying data generation steps in colab with GPU with the dataset you mentioned here. I am using below command:
!python3 generate_data.py --filesize 3 --threads 2 --outpath TFRecords --imagespath ./unlv_images --ocrpath ./unlv_xml_ocr --tablepath ./unlv_xml_gt --visualizeimgs 0 --visualizebboxes 0

It is running overnight but not ending.Seems it goes to infinite loop. Am I doing anything wrong here? Please suggest.
