System.OverflowException: Arithmetic operation resulted in an overflow

[vanderryan]

Describe the bug Expanded dataset. 14 Training data inputs,14 Validation data inputs. Each data point has 29 features: [ 65389, 80, 420, 3, etc, etc up to 28 items ], Running with data like this throws: "Unhandled exception. System.OverflowException: Arithmetic operation resulted in an overflow. at System.Convert.ToInt64(Double value)" Error bubbles up from

let (optimizedModel, nMisses) = TrainSequentialClassifier( Mapped( SequentialModel(ClassifierStructure(), _, 0.0), initialParameters ),

To Reproduce Steps to reproduce the behavior: Follow instructions on Github to run via 'dotnet run'. Please note the only version I could get installed was: Microsoft.Quantum.MachineLearning --version 0.23.195983

Expected behavior Program to run despit increase number of features.

Thanks for your report, @vanderryan! It looks like this may be an issue with the QML library, so transferring to the quantumlibraries repo where that can be properly triaged. Thank you!
