Running Detectron2 locally - windows - [Pytorch Config error]

I am trying to run this code locally:https://gist.github.com/shashank524/74d8f46d5de633b84e2265fcc34774de#file-tabledetection-ipynb

After installing required packages, when I am trying to run this line:

import layoutparser as lp# PubLayNetmodel = layoutparser.Detectron2LayoutModel('lp://PubLayNet/faster_rcnn_R_50_FPN_3x/config',extra_config=["MODEL.ROI_HEADS.SCORE_THRESH_TEST", 0.81],label_map={0: "Text", 1: "Title", 2: "List", 3:"Table", 4:"Figure"})

I receive this error:

OSError: [Errno 22] Invalid argument: 'C:\\Users\\username/.torch/iopath_cache\\s/f3b12qc4hc0yh4m\\config.yml?dl=1.lock'

I looked into the directory and there was no config file available.I tried to download the config file from here (https://layout-parser.readthedocs.io/en/latest/notes/modelzoo.html) and put it in the directory but it didn't solve the issue!
