The Program class

The only change in the Program class was the help text to indicate usage for predict requires a filename, not a string:

if (args.Length != 2)
{
    Console.WriteLine($"Invalid arguments passed in, exiting.{Environment.NewLine}                    {Environment.NewLine}Usage:{Environment.NewLine}" +
        $"predict <path to input json file>{Environment.NewLine}" +
        $"or {Environment.NewLine}" +
        $"train <path to training data file>{Environment.NewLine}");

        return;
}
