ImportError: cannot import name 'KMeans' from sklearn.cluster

ImportError: cannot import name ‘KMeans’

$ python -c "from sklearn.cluster import KMeans"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'KMeans' from 'sklearn.cluster'

Why this happens

• Outdated scikit-learn or shadowed module.

Fix

• Upgrade scikit-learn and remove shadowing.

Wrong code

from sklearn.cluster import KMeans
km = KMeans
km.fit([[0,1],[1,0]])

Fixed code

from sklearn.cluster import KMeans
km = KMeans(n_clusters=2, random_state=42)
X = [[0,1],[1,0],[0.4,0.6]]
print(km.fit_predict(X))
