DSFDDetector creation problem

[rkinas]

I encountered probem with DSFDDetector creation (rest of detectors work without any problem) .. Any idea for fixing problem?

detector = face_detection.build_detector("DSFDDetector",confidence_threshold=.5, nms_iou_threshold=.3)

raises error

I found a solution and probably bug in code ...

file: detect.py

model_url = "http://folk.ntnu.no//haakohu/WIDERFace_DSFD_RES152.pth"

should be

model_url = "http://folk.ntnu.no/haakohu/WIDERFace_DSFD_RES152.pth"

works fine for me

Thanks for pointing out the error! Please notify me with any others you encounter, as I've only tested my code on macOS and ubuntu 16.04/18.04.
