As https://github.com/pytorch/pytorch/issues/2575 said That's also why changing import order can fix things, because if you change it in a way that loads all your "static TLS" libraries first, then future "dynamic TLS" libraries will resize the DTV like normal, I just insert import cv2 at the 1st line of https://github.com/rupeshs/fastsdcpu/blob/main/src/app.py and solve the issue.
