I'm trying to train my own NLP model with CreateML with Xcode playground, and going through the tutorial by Apple: https://developer.apple.com/documentation/createml/creating_a_text_classifier_model
but the program terminated by EXC_BAD_ACCESS (code=1, address=0x0)
I found some solution from the Internet, they stated that the pointer is pointing to NULL when trying to access the variable
import Foundation
import CreateML
let source = "icecream"
let data = try MLDataTable(contentsOf: URL(fileURLWithPath: "/path/to/\(source).csv"))
let (trainingData, testingData) = data.randomSplit(by: 0.8, seed: 0)
// program stopped here
let sentimentClassifier = try MLTextClassifier(trainingData: trainingData, textColumn: "text", labelColumn: "sentiment")
// error
error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=1, address=0x0).
// output
