Hey all,

I'm having issues with Project 4 Part 2's .mlmodel file. When I import the .mlmodel file that I created in Create ML, the prediction input values don't match what Paul's example on screen shows. My wake and coffee input values according to the .mlmodel are Int64, instead of the Double that Paul's example on screen shows.

Because of that, the calculateBedtime function fails to work, throwing the following message:

Cannot convert value of type 'Double' to expected argument type 'Int64'
Replace 'Double(hour + minute)' with 'Int64(Double(hour + minute))'

I've recreated the file multiple times to try to fix it, but I keep running into the same problem.

Any ideas?

I got the same Int64 values. You should get it to work with:

let prediction = try? model?.prediction(wake: Int64(hour + minute), estimatedSleep: sleepAmount, coffee: Int64(coffeeAmount))

I'm having the same issue.

I have the same issue. The following fix seems to work:

Replace the line:

let prediction = try model.prediction(wake: Double(hour + minute), estimatedSleep: sleepAmount, coffee: Double(coffeeAmount))

with:

let prediction = try model.prediction(wake: Int64(hour + minute), estimatedSleep: sleepAmount, coffee: Int64(coffeeAmount))
