Problem in the lesson #5

[interogativ]

The reason for this is that the model fit function requires a callback class reference and for the attributes of that reference to have been initialized. While this is normally done for the user in the calling subclass (learner) it is not done in lesson 5 because Jeremy has you building this yourself. So you have two choices:

1. define you own callback class with the appropriate attributes.
2. Make the changes to the model fit routine to check to see if the callbacks class and attributes are appropriately defined before using them as suggested here
