I had an error on this line
train_x, test_x, train_y, test_y = train_test_split(features, labels, test_size=0.3, random_state=0)
they said
ValueError: With n_samples=0, test_size=0.3 and train_size=None, the resulting train set will be empty. Adjust any of the aforementioned parameters.
How can I solve this?
