but it seens work for keras model but it is tensorflow model .

I believe you can use the principle here. you can use a costume callback for the purpose as well. try tracing these variables: self.weights
self.biases
I think it will help.

is there anyway to save the trained model?

you can add this to model:

def save_model(self):
    saver = tf.train.Saver()
    save_path = "meltpool_model.ckpt"
    saver.save(self.sess, save_path)
    print(f"Model saved at {save_path}")

def load_model(self):
    saver = tf.train.Saver()
    save_path = "meltpool_model.ckpt"
    saver.restore(self.sess, save_path)
    print(f"Model loaded from {save_path}")    

To save the model you should call save_model after training. and when you want to use the saved model before the train call the load_model.
