AttributeError: 'XGBClassifier' object has no attribute 'named_steps'

Turns out that there is an issue; I tried to use the model to classify a certain bug but it didn't work. However, it seems like that there are some steps that may help in the Discussion so I will try those out first. Thanks!

Edited: Sorry, the steps in the Discussion didn't resolve this issue.
