Increase reid mutlibackend preprocessing robustness by clipping the detections to ((0, w), (0, h)) by Justin900429 in https://github.com/mikel-brostrom/yolo_tracking/pull/1187. This error may arise if the detector generates bboxes that ends outside the input image. It happens when the detector has been trained, not following best practices (clean up your ground truth, clip the output of the model...).
