python - 需要解压的值太多(预计有 3 个)

Question

使用 python 将数据拆分为训练和测试时，出现以下错误

" too many values to unpack (expected 3)"

这是我的代码:

from sklearn.model_selection import train_test_split
X_train, X_test, y_train = train_test_split(features,prices, test_size=0.2, random_state=10)
print("Training and testing split was succesful")

这是预期的输出:“训练和测试拆分成功”。

Answer 1

看来您错过了 y_test。

试试这个:

X_train, X_test, y_train, y_test = train_test_split(features,prices, test_size=0.2, random_state=10)
