How to save ColumnTransfers ( scaler , one hot encoder , imputer..etc) for later predictions

How to Save scalers and encoders for later use on prediction
I tried to save and load a model.
But got KeyError: 0 when tried to load it
cat_steps = Pipeline([
('si', SimpleImputer(strategy='constant', fill_value='MISSING')),
('imputer', SimpleImputer(strategy='constant', fill_value='missing')),
('ohehot', OneHotEncoder(sparse=False, handle_unknown='ignore'))
])
categoricalColumns = ['advCode','advisorAge','Totalbonus']
num_steps = Pipeline([
('imputer', SimpleImputer(strategy='median')),
('scaler', StandardScaler()) ])
numericalColumns = ['height',"weight"]
preprocessor = ColumnTransformer(transformers=[('num', num_steps, numericalColumns),
('cat', cat_steps, categoricalColumns)])
X_train = preprocessor.fit_transform(X_train)
from sklearn.externals import joblib
joblib.dump(preprocessor, 'myfile.pkl')
preprocessor = load('filename.pkl')

I dont think that error is related to saving or loading. Show the full stack trace of error along with the code that is producing it.
