解决方案：‘Series‘ object has no attribute ‘xxxx‘

---

一、现象

......
model.fit(X_train, y_train)
y_pred = model.predict(X_test)
recall = recall_score(y_test, y_pred)
precision = precision_score(y_test. y_pred)
......

执行语句到**“precision = precision_score(y_test. y_pred)”**这里发现报错

‘Series’ object has no attribute ‘y_pred’

二、解决方案

定位到“precision = precision_score(y_test. y_pred)”

precision = precision_score(y_test. y_pred)

发现y_test. y_pred，之间不应该是“.”，而是“,”才对

“.”转成“,” ，即可解决

precision = precision_score(y_test, y_pred)

重新跑，跑到**“precision = precision_score(y_test, y_pred)”**，不会再报错误
