This error message is raised when you try to call the `diff` method on a `Float64Index` object. The `diff` method is not available for `Float64Index` objects, as it is only available for numerical data types like `Series` and `DataFrame`.
To resolve this error, you can either convert the `Float64Index` object to a numerical data type that supports the `diff` method, or use a different method to perform the desired operation.
