Marathon run isn't working properly

[sahara108]

I have found that running the scripts by using marathon run myscript.swift doesn't work properly. It hangs the program forever. I end up build an executable program to use it.
I am using 10.13 Beta (17A291j). The code is written by swift 4

Hi @sahara108. Could you provide some more debuggable information? What kind of script are you trying to run? Does it have any dependencies? I haven't tried Marathon on 10.13 Beta yet, so it might have something to do with it as well.

Just try to use the Vision framework to detect and crop face from a picture.

if #available(OSX 10.13, *) {
    let processingQueue = OperationQueue()
    processingQueue.qualityOfService = .userInitiated
    processingQueue.maxConcurrentOperationCount = 1
    for item in urls {
        
        if let img = CIImage(contentsOf: item) {
            processingQueue.addOperation {
                let handler = FaceCrop()
                NSLog("Start process image at \(item)")
                handler.processImage(inputImage: img)
                while (handler.isProcessing) {
                    RunLoop.current.run(mode: .defaultRunLoopMode, before: Date(timeInterval: 1, since: Date()))
                }
                
                NSLog("Start process output images of \(item)")
                if let out = handler.outputImage {
                    save_cgimage_to_jpeg(input: out, destination: faceDir.appendingPathComponent(item.lastPathComponent))
                }
            }
            
            processingQueue.waitUntilAllOperationsAreFinished()
//            wait(8)
        }
    }
    
    
} else {
    // Fallback on earlier versions
}

And you're saying that the exact same code works if you put it inside an executable program instead? Are you using the Swift Package Manager or a command line app from Xcode? What is the output if you run the script using the ---verbose flag?

Hi @sahara108

Could you try this again?

The code looks like it might fall of the end in certain places.

For example, the while loop may go forever ?

Or you may execute it on a system that isn't 10.13 ?

Try to handle all of these pitfalls and see if any of these reasons are to blame first.
