'tuple' 对象没有属性 'data'

Question

我正在练习分类。当我打印它时，我可以看到 iris 具有这两个属性。但我仍然遇到同样的错误。

from sklearn import datasets
from sklearn.metrics import classification_report
from sklearn.naive_bayes import GaussianNB
from sklearn.model_selection import train_test_split

iris = datasets.load_iris(),

X = iris.data
y = iris.target

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33, random_state=42)

nb_classifier = GaussianNB()

nb_classifier.fit(X_train, y_train)

y_pred = nb_classifier.predict(X_test)
print(classification_report(y_test, y_pred))

Answer 1

去掉

末尾的,

iris = datasets.load_iris(),

否则iris成为一个元素的元组。您的行与：

iris = (datasets.load_iris(),)

'tuple' 对象没有属性 'data'

'tuple' object has no attribute 'data'

python
