CreateML标记化时出现“执行被中断”错误

Question

我创建了一个简单的macOS游乐场来制作coreML文本分类器，如下所示：

import Cocoa
import CreateML

let url = URL(string: "https://github.com/novinfard/profiler-sentiment-analysis/raw/master/ml-model/essays.csv")
let data = try MLDataTable(contentsOf: url!)
let (trainingData, testingData) = data.randomSplit(by: 0.8, seed: 5)
let sentimentClassifier = try MLTextClassifier(trainingData: trainingData,
                                               textColumn: "TEXT",
                                               labelColumn: "cEXT")
// Training accuracy as a percentage
let trainingAccuracy = (1.0 - sentimentClassifier.trainingMetrics.classificationError) * 100

// Validation accuracy as a percentage
let validationAccuracy = (1.0 - sentimentClassifier.validationMetrics.classificationError) * 100

print("training accuracy -> \(trainingAccuracy) validation accuracy ->\(validationAccuracy)")

但是我收到“执行被中断”错误。

以下是该过程中的日志：

我该如何解决？
