AttributeError: 'time.struct_time' 对象没有属性 'perf_counter'

Question

从时间导入 perf_counter 导入时间

xg_cl = XGBClassifier(n_estimators=70)

time = time.localtime(time.time()) training_start = time.perf_counter()

xg_cl.fit(X_train, y_train) training_end = time.perf_counter()

prediction_start = time.perf_counter()

preds = xg_cl.predict(X_test)

prediction_end = time.perf_counter()

acc_xg_cl = (preds == y_test).sum().astype(float) / len(preds)*70

xg_cl_train_time = training_end-training_start

xg_cl_prediction_time = prediction_end-prediction_start

print("训练消耗的时间：%4.3f" % (xgb_train_time))

print("预测耗时：%6.5f 秒" % (xg_cl_prediction_time))

运行代码，我得到这个错误
