Thank you Ben Webb for your answer.

I have modified it according to my requirements and generated the model successfully.

But I have a question regarding *rand_seed* value. It is mentioned that,

*"Set a different value for rand_seed to get a different final modelenv = Environ(rand_seed=-49837)"*.

So if I wish to generate multiple models, then which value (exact number) should I use?

Thanks in advance.
