Description

I have tried to save trained SASRec model.

pickle, tf.saved_model.save, model.save(), and surprise.dump are not working.

While saving, I got warning saying 'Found untraced functions', and while loading, 'AttributeError: 'SASREC' object has no attribute 'seq_max_len''.

Plz someone let me know how to save and load SASRec model!

Research direction
Review the SASRec model class definition and its serialization methods. Check if there is a custom save/load function or if the model inherits from Keras or TensorFlow. Also, check the repository's documentation or examples for model persistence.
