Error with tensorflow code in Mojo

[Swaymaw]

Please, explain the error received when running this cell and how to make sense of it. Also, explain possible methods to fix this.

I also tried the %%python mode and copied a working python code but still mojo says that python part returns an error. Does anybody know what the issue is? If yes, Please Help Me, I really wanna learn Mojo and use it for my day-to-day AI/ML applications.
