Hi @ParikhKadam @dharaneepatel15

I have been trying to recreate your model code. But it has been keep throwing me below error. I have installed all six mentioned dependencies. Don't know how to fix this issue. Here's the link of my google colab notebook .

Any idea and suggestion would be highly appreciated. Thanks
