Python: 'StandardScaler' object has no attribute '_validate_data'

Question

I recently updated my sklearn. However, since the upgrade I'm getting the error "'StandardScaler' object has no attribute '_validate_data'". The following is a snippet of the code:

Xs = pd.DataFrame([[10,20], [20,30], [30,40], [40,50]])
scalerx = preprocessing.StandardScaler()
scalerx.fit(Xs)

Finally, check your code. Why does `scalerx` become `scalex`? — sentence, Jul 04 '20 at 14:08
version is 0.23.1. This code itself gives the "Attribute error". Made the change 'scalerx' to to the code. Thanks in advance! — Kalpit Narvekar, Jul 04 '20 at 14:57

You can scale the data frame using

from sklearn.preprocessing import StandardScaler

Xs = pd.DataFrame([[10,20], [20,30], [30,40], [40,50]])
scalerx = StandardScaler()
X = scalerx.fit_transform(Xs.values)

Issue resolved automatically.. Restarting the machine once after upgradation of the library did the job. Thanks all! :) – Kalpit Narvekar Jul 06 '20 at 04:40
