Еще один простой способ - PyCM (мной), который поддерживает многоуровневый анализ путаницы.
Применимо к вашей задаче:
>>> from pycm import ConfusionMatrix
>>> y_true = [1, -1, 0, 0, 1, -1, 1, 0, -1, 0, 1, -1, 1, 0, 0, -1, 0]
>>> y_prediction = [-1, -1, 1, 0, 0, 0, 0, -1, 1, -1, 1, 1, 0, 0, 1, 1, -1]
>>> cm = ConfusionMatrix(actual_vector=y_true,predict_vector=y_prediction)
>>> print(cm)
Predict -1 0 1
