the Error during UnmarshalBinary(b)

[annatelegina]

Hello everyone! I have the following problem during testing yolo model.

func Example_gorgonia() {

    backend := gorgonnx.NewGraph()
    model := onnx.NewModel(backend)

    b, err := ioutil.ReadFile("last_model.onnx")
    if err != nil {
            log.Fatal(err)
    }

    err = model.UnmarshalBinary(b)
    if err != nil {
            log.Fatal(err)
    }
    tensor := tensor.New(tensor.WithShape(1, 3, 640, 640), tensor.Of(tensor.Float32))
    model.SetInput(0, tensor)
    err = backend.Run()
    if err != nil {
            log.Fatal(err)
    }
    output, _ := model.GetOutputTensors()
    fmt.Println(output[0])
}

func main() {
    Example_gorgonia()
}

The output is:
panic: runtime error: index out of range [0] with length 0

What should I do in this situation? Who has already tackled with this problem?
