[QUESTION|BUG] Mismatched type 'Mat' and 'opencv::opencv::hub::core::Mat'

[charl-alvs]

mismatched type 'Mat' and 'opencv::opencv::hub::core::Mat' have similar names, but are actually distinct types perhaps two different version of crate 'opencv' are being used?

let mut frame = imread("images/persons.jpg", 1).unwrap();
let (bboxes, class_ids, confidences) = model.forward(&frame, 0.25, 0.4).unwrap();

I guess this could be a reason of an error (I'm using a rather old versions on my personal computer, so I did not faced it). What version of OpenCV are you using?
