調用sklearn的compute_class_weight提示錯誤”compute_class_weight() takes 1 positional argument but 3 were given“，解決辦法為函數里加上參數名：
from sklearn.utils.class_weight import compute_class_weight label = [0] * 9 + [1] * 1 + [2, 2] classes = [0, 1, 2] weight = compute_class_weight(class_weight='balanced', classes=classes, y=label) print(weight)
