Which app do I import to fix this error?

Wait, now. You are saying to install a later version of sklearn and then use the syntax that you
put in your post?

No you get that error because you use a never version.

# This only work in older version that's why you get a error
from sklearn.preprocessing import Imputer

# This is what you should now in newer versions,this dos now just he same as line over 
from sklearn.impute import SimpleImputer

Again, what is with this sklearn version 0.0. That really makes no sense at all.

How dos you check to get this?
I did show you how to check version.

>>> from sklearn import base
 
>>> base.__version__
'0.22.2.post1'
