TypeError: DBSCAN min_samples out of range

TypeError: min_samples out of range

$ python -c "from sklearn.cluster import DBSCAN; DBSCAN(min_samples=0).fit([[0,0],[1,1]])"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: min_samples must be an integer >= 1

Why this happens

Setting min_samples to 0 or negative is invalid.

Fix

Use at least 1; common values are 3–10 depending on data density.

Wrong code

from sklearn.cluster import DBSCAN
DBSCAN(min_samples=0)

Fixed code

from sklearn.cluster import DBSCAN
DBSCAN(min_samples=5)
