I'm testing a coreml model within MessageFilterExtension.However, with the same input, the model.prediction crash randomly.
The crash is in the auto generated model class, prediction function:
func prediction(input: AISMSFilterInput) throws -> AISMSFilterOutput {
let outFeatures = try model.prediction(from: input)
let result = AISMSFilterOutput(output1: outFeatures.featureValue(for: "output1")!.multiArrayValue!)
return result
}
The outFeatures has an error:
expression produced error: error: /var/folders/6m/y69_5m7170q1kztp356nhhf80000gn/T/expr43-f2ff4b..swift:1:65: error: use of undeclared type 'MLFeatureProvider'
Swift._DebuggerSupport.stringForPrintObject(Swift.UnsafePointer<MLFeatureProvider>(bitPattern: 0x102f342f0)!.pointee)
^~~~~~~~~~~~~~~~~
How to debug this? Thanks.
