如何在 Swift Playground 中使用 .mlmodel? [英] How do I get the .mlmodel to be used in Swift Playground?

问题描述

我已经将 .mlmodel 转换为 .mlmodelc ，并将其放在资源文件夹中.我使用 Vision framework 和 MNIST 模型，遵循本教程 (

I have already converted the .mlmodel to .mlmodelc , and I have put it in the resources folder. Im using Vision framework and MNIST model, following this tutorial (https://www.youtube.com/watch?v=bOg8AZSFvOc), but using swift playground.

What am i missing? (im using .playground files, not .playgroundbook files)

line of code:

 guard let visionModel = try? VNCoreMLModel(for: MNIST().modelc) else {fatalError("can not load Vision ML model")}

Error message:

use of undefined identifier 'MNIST'

解决方案

Playground doesn't recognize the .mlmodel file by default, so we need an iOS Project to help us find the compiled mlmodelc folder, and copy the mlmodelc folder to playground's resource folder, and the auto generated helper class to playground's source folder and change it to public. Then it works!
