log the # of parameters when loading the model

When loading a model, I think it is helpful to log the # of parameters and the path of the stored model.

This is the wrong way to use logging. A logger level shouldn't be set in the code. It should be set in your script when you actually use it. You may want to have the # of parameters printed, but other people may not care to see it.
