无法使用MLModel.compileModel(at :)加载CoreML模型 [英] Unable to load CoreML model using MLModel.compileModel(at:)

问题描述

我正在尝试使用以下代码加载.mlmodel文件:

I am trying to load a .mlmodel file using the following code:

let paths =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
var documentsUrl = paths[0]
documentsUrl.appendPathComponent("parallel.mlmodel")
do {
    let compiledModelUrl = try MLModel.compileModel(at: documentsUrl)
    let model = try? MLModel(contentsOf: compiledModelUrl)
} catch {
    print(error.localizedDescription)
}

但是我收到错误The file couldn’t be saved.，该模型确实存在于该位置.

But I get the error The file couldn’t be saved., the model does exist at that location.

推荐答案

我找到了答案.当我以调试模式将应用程序从Mac部署到iphone时，我也遇到了此问题.实际上，代码没有错，这是另外一回事.我做了两件事，首先登录icloud(icloud与开发的配置文件有关吗?)，其次删除该应用程序并将其重新部署到iphone.现在解决了这个问题. 尽管我不确定哪个可以解决我的问题，但我认为这是我做的第二件事.让我知道是否有人找到背后的原因.

I found the answer. I also encountered this problem when I deploy an app to an iphone from Mac in debug mode. Actually, there is nothing wrong with the code, it is something else. I did two things, first signed in to icloud (does icloud have anything to do with its provisioning profile for development?), secondly delete the app and re-deploy the app to the iphone. It solves the problem now. Although I am not sure which one solves my problem, I assume it is the second thing I did. Let me know if anyone found the reason behind.
