name 'StandardScaler' is not defined

I have installed scikit-learn 0.23.2 via pip3, however, I get this error from my code

Traceback (most recent call last):
  File "pca_iris.py", line 12, in <module>
    X = StandardScaler().fit_transform(X)
NameError: name 'StandardScaler' is not defined

I searched the web and saw similar topics, however the version is correct and I don't know what to do further. The line import sklearn is in the top of the script.

Any thought?

StandardScaler is a method under sklearn.preprocessing. You need to import the StandardScaler like this:

from sklearn.preprocessing import StandardScaler
X = StandardScaler().fit_transform(X)

Or

import sklearn
X = sklearn.preprocessing.StandardScaler().fit_transform(X)
