CoreML error: Could not cast value of type MLFeatureValue to MLFeatureProvider
I have a CoreML model that expects the following input:
I have an array of data:
let data:MLMultiArray = [x:y]
And, I'm using CoreMLHelpers to reshape my data array to the correct input shape:
var shapedData = MultiArray<Double>(data)
shapedData = mfcc.reshaped([1, 99, 40])
I then create an MLFeatureValue
wrapper around that data:
let inputWrapper = MLFeatureValue(multiArray: mfcc.array)
And then attempt to perform a prediction:
let prediction:[Double:Any] = modelTester.makePrediction(inputs: inputWrapper)
In my makePrediction
method, I have the following line that seems to be the problem:
let prediction = try mlModel?.prediction(from: inputs as! MLFeatureProvider)
When I run the code, I get the following error:
Could not cast value of type 'MLFeatureValue' (0x7fff9582d0f8) to 'MLFeatureProvider' (0x7fff9c86d008).
Does anyone have any insight into where in this chain I'm going wrong? Thanks!
