Cannot read ONNX model

[benjamingb]

I'm trying the example of loading a YOLOv8 model in ONNX format and I'm getting this error, am I doing something wrong?

    let classes_labels: Vec<&str> = vec!["person", "bicycle", "car", "motorbike", "aeroplane", "bus", "train", "truck", "boat", "traffic light", "fire hydrant", "stop sign", "parking meter", "bench", "bird", "cat", "dog", "horse", "sheep", "cow", "elephant", "bear", "zebra", "giraffe", "backpack", "umbrella", "handbag", "tie", "suitcase", "frisbee", "skis", "snowboard", "sports ball", "kite", "baseball bat", "baseball glove", "skateboard", "surfboard", "tennis racket", "bottle", "wine glass", "cup", "fork", "knife", "spoon", "bowl", "banana", "apple", "sandwich", "orange", "broccoli", "carrot", "hot dog", "pizza", "donut", "cake", "chair", "sofa", "pottedplant", "bed", "diningtable", "toilet", "tvmonitor", "laptop", "mouse", "remote", "keyboard", "cell phone", "microwave", "oven", "toaster", "sink", "refrigerator", "book", "clock", "vase", "scissors", "teddy bear", "hair drier", "toothbrush"];
    let mf = ModelFormat::ONNX;
    let net_width = 640;
    let net_height = 640;
    // let class_filters: Vec<usize> = vec![15, 16];
    let class_filters: Vec<usize> = vec![];
    let mut model = ModelUltralyticsV8::new_from_file("pretrained/yolov8n.onnx", None, (net_width, net_height), mf, DNN_BACKEND_CUDA, DNN_TARGET_CUDA, vec![]).unwrap();
    let mut frame = imread("images/dog.jpg", 1).unwrap();
    let (bboxes, class_ids, confidences) = model.forward(&frame, 0.25, 0.4).unwrap();
    for (i, bbox) in bboxes.iter().enumerate() {
        rectangle(&mut frame, *bbox, Scalar::from((0.0, 255.0, 0.0)), 2, LINE_4, 0).unwrap();
        println!("Class: {}", classes_labels[class_ids[i]]);
        println!("\tBounding box: {:?}", bbox);

    }

I have two guesses:

1. OpenCV version (you have 4.6.0 based on error message). object detection: yolov8 onnx opencv DNN ultralytics/ultralytics#1836 I think that version 4.7.0 should do the trick.
2. OpSet for ONNX. It should be 12. yolov8 export as onnx issue (8.0.43) ultralytics/ultralytics#1097

Hi

I updated to version opencv 4.8.0 but now I get another error

Can't process detection,  error: OpenCVError(Error { code: "StsAssert, -215", message: "OpenCV(4.8.0) /home/benjamin/dist/opencv-4.8.0/modules/dnn/src/layers/reshape_layer.cpp:109: error: (-215:Assertion failed) total(srcShape, srcRange.start, srcRange.end) == maskTotal in function 'computeShapeByReshapeMask'\n" })

Does it only work with the darknet?

[LdDl]

May you provide link to a model and image you trying to run through the detection function?
I think that something could be wrong with the shape of the model (I guess the model is custom?): input[0] = [ 1 64 3549 ]. ultralytics/ultralytics#1050

[benjamingb]

The problem was that I had the dimensions of the network wrong, I had it at 416, I changed it to 640 and it worked.

let net_width = 640;
let net_height = 640;

Thank you for your help and for the great work in developing the lib.

Are you planning to update the opencv-rust version to 0.9.x in your library soon?

[LdDl]

Glad to hear that it works!
Yes, I'm planning to update Cargo.toml to include 0.9 version of OpenCV bindings, but it will happen in a couple of weeks after my vacation and checks that my other projects depending on this package won't be broken

[benjamingb]

Question
I converted a Yolov8m model to Onnx,
the model works fine, but when I put a video to detect the objects, the video goes very slow, if I use darknet the video goes at normal speed, only when I load the .onnx model the video gets super slow, the video has 29 FPS, do you know why that happens ?

[LdDl]

1. If using GPU check CUDA actually works for both ONNX and Darknet weights
2. Check if batch is the same for both configurations (most of time this is the issue)
3. Check the input size / classes num for both configurations

I believe it should be investigated in details in both Rust and Python OpenCV's bindings then if any of three clauses above does not take place.

[LdDl]

Using cargo run (in case of cargo build it should be faster), RTX 3060 (CUDA is enabled)
TLDR:

• v7 darknet. Average:

real    0m0,5s
user    0m0,3s
sys     0m0,2s

• v4 darknet. Average:

real    0m0,6s
user    0m0,4s
sys     0m0,3s

• v8m onnx. Average:

real    0m0,7s
user    0m0,4s
sys     0m0,2s

• v8s onnx. Average:

real    0m0,5s
user    0m0,4s
sys     0m0,2s

Seems like, that M-model just takes more resources on computing. But should it affect FPS so much in your case?

Glad to hear that it works! Yes, I'm planning to update Cargo.toml to include 0.9 version of OpenCV bindings, but it will happen in a couple of weeks after my vacation and checks that my other projects depending on this package won't be broken

Just bumped to 0.91.3 version
