ModuleNotFoundError：没有名为“sklearn.utils._testing”的模块

Question

from sklearn.utils._testing import ignore_warnings

ModuleNotFoundError: No Module named 'sklearn.utils._testing'

How Could I solve this problem? My sklearn version is 0.21.3

Answer 1

Those who are facing ModuleNotFoundError: No module named 'sklearn.utils.testing'

import sklearn
estimators = sklearn.utils.all_estimators(type_filter=None)
for name, class_ in estimators:
    if hasattr(class_, 'predict_proba'):
        print(name)

Answer 2

In version 0.21.3: sklearn.utils. testing

from sklearn.utils.testing import ignore_warnings

In version 0.24.1 or later Link :
sklearn.utils. _testing

from sklearn.utils._testing import ignore_warnings

Answer 3

For those facing the following error ModuleNotFoundError: No module named 'sklearn.utils.testing', an alternative solution to that of @desertnaut would be to load from the root rather than from testing:

from sklearn.utils import all_estimators

Answer 4

As mentioned by @ywbaek, the following import fixes this problem for Scikit-learn version: 0.21.3 :

from sklearn.utils.testing import ignore_warnings

sklearn.utils._testing may be introduced in a later version (as observed from SK Github Repo )
