Exception when transforming LabelEncoder with keyword argument #26854
Description
Describe the bug
The transform method of LabelEncoder raises an exception when providing y with a keyword argument.
I mentioned this in discussion #26841 but I am more and more certain this is a bug. And even if it isn't and there is some good reason it fails, the error message is completely unclear since it refers to a parameter that is not present in the method.
Steps/Code to Reproduce
from sklearn.preprocessing import LabelEncoder
le = LabelEncoder().fit_transform(y=[0, 2, 2, 0])Expected Results
Normal output of the transform method. Same as when calling LabelEncoder().fit_transform([0, 1, 2]) (withoyt y=), which in the above example would be array([0, 1, 1, 0], dtype=int64).
