Saving and loading models in ML Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to save a trained model using joblib.

ML Python

import joblib

# Assume model is already trained
joblib.[1](model, 'model.pkl')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'load' instead of 'dump' to save the model.

Using 'save' which is not a joblib function.

The joblib.dump() function is used to save a model to a file.

medium

Complete the code to load a saved model using joblib.

ML Python

import joblib

model = joblib.[1]('model.pkl')

Drag options to blanks, or click blank then click option'

Common Mistakes

Using 'dump' instead of 'load' to load the model.

Using 'save' which is not a joblib function.

The joblib.load() function reads a saved model from a file.

Fix the error in saving a Keras model to HDF5 format.

ML Python

💡 Hint

Common Mistakes

Using 'dump' which is not a Keras model method.

Using 'load' instead of 'save'.

Keras models are saved using the save() method.

4fill in blank

hard

Fill both blanks to load a Keras model and evaluate it.

ML Python

from tensorflow.keras.models import [1]

model = [2]('model.h5')
loss, accuracy = model.evaluate(x_test, y_test)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'save_model' which is for saving, not loading.

Using 'load' which is not imported from keras.models.

The function load_model from Keras loads a saved model from a file.

5fill in blank

hard

Fill all three blanks to save a scikit-learn model, load it, and make predictions.

ML Python

import joblib

joblib.[1](model, 'model.pkl')
loaded_model = joblib.[2]('model.pkl')
predictions = loaded_model.[3](X_test)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'save' instead of 'dump' to save the model.

Using 'load' incorrectly as a method on the model.

Using 'fit' instead of 'predict' to get predictions.

Use dump to save, load to load, and predict to get model predictions.
