I've found a few other posts such as this one complaining about not being able to import several things regarding sklearn, but I've tried every proposed solution (which comes down to: pip3 install -U and apt install in every situation, also on posts asking about something other than preprocessor), but it still doesn't help.
The problem I'm having is:
>>> import sklearn
>>> sklearn.__version__
'0.20.3'
>>> sklearn.preprocessor
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'sklearn' has no attribute 'preprocessor'
>>> from sklearn import preprocessor
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'preprocessor'
The output when installing the supposedly correct packages is as follows:
$ pip3 install -U scikit-learn

As you can see, the package should be installed correctly in two different ways, but it still doesn't work. I've also tried uninstalling one of those (in case they interfered with each other), but that didn't solve anything either.
Does anyone know why this is not working for me? If I need to provide with any other information about my installation I'd be happy to provide it.
This happened to me as well before, Here is the solution
import sklearn.preprocessing # or from sklearn import preprocessing
