NameError Traceback (最近一次调用最后一次) C:\Users\VAISHN~1\AppData\Local\Temp/ipykernel_6520/2922578464.py in 3 'kernel': ['rbf']} 4 ----> 5 optimization_params=GridSearchCV ( 6 SVC(), 7 param_grid,

NameError：名称“GridSearchCV”未定义
这是我的代码：

param_grid={'C': [0.5,1,10,100],
     'gamma': ['scale',1,0.1,0.001,0.0001],
     'kernel': ['rbf']}

optimal_params=GridSearchCV(
    SVC(),
    param_grid,
    cv=5,
    scoring='accuracy',
    verbose=0
)
optimal_params.fit(X_train_scaled,y_train)
print(optimal_params.best_params_)
