It seems like you encountered an error stating that the name 'StandardScaler' is not defined. This error typically occurs when you try to use a variable or function that has not been defined or imported. To resolve this issue, you need to import the 'StandardScaler' class from the appropriate library before using it. For example, if you are working with scikit-learn, you can import it like this: ```python from sklearn.preprocessing import StandardScaler ``` Make sure that you have the required library installed and imported correctly in your code.
