Caso alguém possa ajudar. O problema é o seguinte.
Estou no Curso Regressão Linear II, na parte que trata sobre "Criando os datasets de treino e de teste", coloquei o comando informado no curso, que é:
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=2811)
Retornando o seguinte erro:
ValueError Traceback (most recent call last) in ----> 1 X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=2811)
