Machine Learning Error when loading mlmodel "No known class for loading model type > MLModelType_pipelineClassifier"

Question

I have created a mlmodel with Playground and imported into my Xcode project though when it runs I'm getting this error.

The error is also flagged here in the code of the mlmodel.

ObjectClassifier[24610:8307770] [coreml] MLModelAsset: modelWithError: load failed with error Error Domain=com.apple.CoreML Code=3 "No known class for loading model type MLModelType_pipelineClassifier" UserInfo={NSLocalizedDescription=No known class for loading model type MLModelType_pipelineClassifier}

Why would the code that is automatically created when making the mlmodel in the playground be causing this error?

Trebuchet

It has something to do with the type of model that is created by the playground as I can get my code to run no problem with a "Custom Vision" model. The "Custom Vision" model is of type : Neural Network Classifier and the playground model is of type : Image Classifier – Trebuchet

For me the problem is with IOS-11. I faced the same issue, then I tried with IOS12 device and it works fine.

They really need to change the documentation as they say it's compatible with iOS11 – Trebuchet

I was trying to do some coin classification using CoreML, but it turns out to work no good. – Bedford

@uplearnedu.com I'm using about 1800 images and I shifted to turicreate. Now it seems to work better. – Bedford

I'd like this to work with iOS 11... it should do right? – Mcanally

@Mcanally Yeah it should but I'm not sure if it really works now for iOS 11, I think you can try a demo. – Bedford
