tensorboard = TensorBoard(log_dir='./log')
checkpoint = ModelCheckpoint(filepath='./log/best_weights.h5', monitor="out_1_loss", save_best_only=True, verbose=0)callback_lists = [F1Score, tensorboard, checkpoint]
hist = model.fit(X_tra, y_tra, batch_size=batch_size, epochs=1, validation_data=(X_val, y_val),callbacks=callback_lists, verbose=1)
设置监控指标， monitor="out_1_loss"。其中out_1_loss为keras中定义的多输出层中的1层的名称。
