The web backend on the server often needs to run multiple processes at the same time, and each process needs to exchange data. This function can be realized in python with the help of multiprocessing. Further, after the process is interrupted, we want developers to receive messages for improvement and maintenance at the first time, which ne ...

Jaccard Index (IoU, degree of overlap)    Jaccard Index (Jaccard coefficient), or Jaccard Overlap (Jaccard Overlap) or intersection over Union (IoU), measures the degree of overlap between the two frames. This index can reflect the proximity between the prediction frame and the real frame, which will be used in calculating loss and N ...
