possibly a typo in assignment 2?

[ghost]

In 'solver.py' line 30
shouldn't

data = {
    'X_train': # training data
    'y_train': # training labels
    'X_val': # validation data
    'X_train': # validation labels  <--
  }

have to be as the following??

data = {
    'X_train': # training data
    'y_train': # training labels
    'X_val': # validation data
    'y_val': # validation labels   <--
  }

This could be trivial..
