Perform transform on test set about feature-selector

[WillKoehrsen]

You should be able to transform the testing set after doing the feature selection on the training data. Assuming train is the training data after selection, you could do this using pandas align

test = pd.get_dummies(test)
train, test = train.align(test, axis=1, join='inner')

This will make sure both dataframes have the same exact columns. axis=1 refers to the columns, and join='inner' keeps only columns in both dataframes.

@WillKoehrsen Thank you this works.

How do I add the target variable back into the dataframe?
