name 'forml' is not defined

The error message you are seeing indicates that you are trying to use a variable or function called "forml" that has not been defined.

To fix this error, you need to define or import the "forml" module in your code before trying to use it. If you are using a third-party library called "forml", make sure it is properly installed and imported in your code.

Alternatively, it could be a typo or a mistake in the variable name. Double-check your code and make sure you are using the correct spelling and syntax.
