I am working on a project “News Classification”. Where the model has to classify(multi-class classification problem) a given text into business, entertainment, politics, sport and tech.
I am using TensorFlow==2.7.0 on Google Colab. I had trained 7 different models. After, training and made prediction on it. When compared to all models, Conv1d performed the best. The best performing model saved model_2.save('saved_model/my_model').It has done well till here.
But, When I want to load the saved model using the code
loaded_model = tf.keras.models.load_model('saved_model/my_model') then, I am getting the below exception:
TypeError                                 Traceback (most recent call last)

      2 # load_model.preditct(val_sentences)
