a more verbose field mismatch error message
 2016-03-17 19:56:33 -07:00

Julian Quick 2cd109fb98 a more verbose field mismatch error message 
This error message can be hard to understand when there are several fields, as shown in the example below. This improves the error message, letting the user know which fields were unexpected or missing.

    import xgboost as xgb
    import pandas as pd
    train = pd.DataFrame({'a':[1], 'b':[2], 'c':[3], 'd':[4], 'f':[2], 'g':2, 'etc etc etc':[11]})
    dtrain = xgb.DMatrix(train.drop('d', axis=1), train.d)
    test = pd.DataFrame({'a':[1], 'b':[2], 'c':[1], 'd':[4], 'e':[2], 'f':[2], 'g':2, 'etc etc etc':[11]})
    dtest = xgb.DMatrix(test)
    modl = xgb.train({}, dtrain)
    modl.predict(dtest)
    
    
    # ValueError: feature_names mismatch: [u'a', u'b', u'c', u'etc etc etc', u'f', u'g'] [u'a', u'b', u'c', u'd', u'e', u'etc etc etc', u'f', u'g']
