As an AI language model, I do not have access to the complete context of your code or the data that you are working with. However, based on the error message that you have provided, it seems like you are trying to use a variable called 'cat_features' that has not been defined or initialized in your code.

Here are some possible reasons why this error message might be occurring:

1. Typographical error: Ensure that you have spelled the variable name correctly and that it matches the name of the variable where it was initially defined.

2. Variable scope: Check that the 'cat_features' variable has been defined in the correct scope and that it is visible to the part of the code where you are trying to use it.

3. Missing import statement: If 'cat_features' is a module or a package, then it is possible that you forgot to import it before using it in your code.

4. Data issue: If 'cat_features' is a data variable, then it is possible that it was not loaded or defined correctly. Ensure that the data is being loaded or defined in the correct format and that it has been properly sanitized.

To fix this error, you should review your code and data to identify where the 'cat_features' variable should be defined or imported and make sure that it is correctly initialized before being used.
