SVM problem - name 'model_SVC' is not defined

I have a problem with this code:

    from sklearn import svm
    model_SVC = SVC()
    model_SVC.fit(X_scaled_df_train, y_train)
    svm_prediction = model_SVC.predict(X_scaled_df_test)

The error message is

NameError
Traceback (most recent call last) ~\AppData\Local\Temp/ipykernel_14392/1339209891.py in ----> 1 svm_prediction = model_SVC.predict(X_scaled_df_test)

NameError: name 'model_SVC' is not defined

Any ideas?
