C2_w3 parameters w1

Hello, I have an issue with parameters w1. I get ‘nonetype’ error. Every exercise I passed, so I don’t know why this happened.

Hi @Nebojsa ,

The error message “None Type” is indicating that the variable parameters has no value, therefore trying to access the element [“W1”] raised the error.
So you need to find out why the variable parameters has no value.
The print statement is useful for debugging. Put a print statement where parameters is returned, that will show you where the problem might be.
