ImportError: cannot import name 'SVC' from sklearn.svm

ImportError: cannot import name ‘SVC’

$ python -c "from sklearn.svm import SVC"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'SVC' from 'sklearn.svm'

Why this happens

• Old or corrupted installation, or shadowing.

Fix

• Upgrade scikit-learn, ensure clean environment.

Wrong code

from sklearn.svm import SVC
clf = SVC
clf.fit([[0,1],[1,0]], [0,1])

Fixed code

from sklearn.svm import SVC
clf = SVC(kernel="rbf", C=1.0)
clf.fit([[0,1],[1,0],[0.5,0.5]], [0,1,0])
print(clf.predict([[0.2,0.8]]))
