# Load dataset
data = pd.read_csv('ratings.csv')
reader = Reader(rating_scale=(1, 5))
dataset = Dataset.load_from_df(data[['userId', 'movieId', 'rating']], reader)

# Split data into training and test sets
trainset, testset = train_test_split(dataset, test_size=0.2)

# Train the SVD model
model = SVD()
model.fit(trainset)

# Make predictions and evaluate the model
predictions = model.test(testset)
rmse = accuracy.rmse(predictions)
print(f'RMSE: {rmse}')
