Error loading model

[joshbeal]

I get the following error when running the sample app after downloading the assets:

Had the same issue and have found a work around. Instead of including MaskRCNN.mlmodel in the project, I compiled it using MLModel.compileModel Swift API on my PC beforehand and then include compiled mlmodelc file in the project.

Try the following step.

1. Compile MaskRCNN.mlmodel using MLModel.compileModel Swift API. You can do it yourself or you can use the attached MaskRCNN.mlmodelc which was compiled by me. https://drive.google.com/file/d/1NYD4BupvIs1Pza_F7jbg8oA5HXLV8FfC/view?usp=sharing

2. Add reference to MaskRCNN.mlmodelc folder (check Create folder references) to your project.

3. Make sure that in Build Phases, MaskRCNN.mlmodelc is added in Copy Bundle Resources section.

4. In Swift code, load mlmodelc file directly instead of mlmodel file.

// instaed of this
//            let model = try VNCoreMLModel(for: MaskRCNN().model)
// use following
            let compiledPath = Bundle.main.path(forResource: "MaskRCNN", ofType: "mlmodelc")
            let compiledUrl = URL(fileURLWithPath: compiledPath!)
            let mlmodel = try MLModel(contentsOf: compiledUrl)
            guard let model = try? VNCoreMLModel(for: mlmodel) else {
                fatalError("can't load Core ML model")
            }

By the way, at first I tried run MLModel.compileModel on my iPhone XS, but it exceeded device's memory limit (2000mb) and crashed. So I switched to run it on my Mac Book Pro.

Finally and more strangely, after this workaround worked, the original code started to work again. I don't know what the hell is going on :(
