The value type for the learningRate key is a Double.
To modify a model’s learning rate midway through an MLUpdateTask, use its resume(withParameters:) method to set a new value for the model’s learning rate. You do this in the progress handler that you specified in the MLUpdateProgressHandlers instance when you created the update task using init(forModelAt:trainingData:configuration:progressHandlers:).
