最佳模型的试用ID

如何解决最佳模型的试用ID

我正在使用 Autokeras 寻找最佳回归模型，我需要绘制最佳模型的学习曲线。但是，我找不到最佳模型的试用 ID。这是我的代码的一部分：

#path for saving the logs

import datetime
%load_ext tensorboard
path = "logs/fit/" + datetime.datetime.Now().strftime("%Y%m%d-%H%M%s")
tensorboard_callback= tf.keras.callbacks.TensorBoard(log_dir=path)

# Creating Keras Search Type
regressor = ak.StructuredDataRegressor(
                                        output_dim=2,loss="mean_squared_error",metrics=["mae","mean_squared_error"],project_name="structured_data_regressor",max_trials=3,directory=None,objective="val_mean_squared_error",tuner=None,overwrite=False,seed=100,)
#Fitting ANN to Training Set - Validation Data Provide --> Validation Split = 0.1111

history = regressor.fit(x = X_train,y = y_train,epochs= 5,callbacks=[tensorboard_callback],validation_split=0.2) 

#Learning Curves
%tensorboard --logdir logs/fit
