我正在使用 OneVsRestClassifier 进行多标签分类。它适用于 LinearSVC,但是当我将其应用于 SVC 时,会出现以下错误:
classifier = OneVsRestClassifier(SVC(class_weight='balanced'))
classifier.fit(X1, y1)
y2 = classifier.predict(X2)
Traceback (most recent call last):
...
File "/usr/local/lib/python2.7/dist-packages/sklearn/multiclass.py", line 219, in predict
return predict_ovr(self.estimators_, self.label_binarizer_, X)
File "/usr/local/lib/python2.7/dist-packages/sklearn/multiclass.py", line 93, in predict_ovr
Y = np.array([_predict_binary(e, X) for e in estimators])
File "/usr/local/lib/python2.7/dist-packages/sklearn/multiclass.py", line 66, in _predict_binary
score = estimator.predict_proba(X)[:, 1]
File "/usr/local/lib/python2.7/dist-packages/sklearn/svm/base.py", line 490, in predict_proba
"probability estimates must be enabled to use this method")
NotImplementedError: probability estimates must be enabled to use this method</code>
有人知道它是什么吗?
