You need to add the attribute into the class: With the attribute defined inside the class, you resolved this error. The problem is you do not need to pass through your parameters through the PCA algorithm again (essentially what it looks like you are doing is the PCA twice). because user no longer has access to unnormalized distribution. Connect and share knowledge within a single location that is structured and easy to search.
