Fixe or suppresses many warnings in examples, including matplotlib complaining about the non-gui backend.

Very nice! A few comments are below, overall LGTM.

In general, I don't think it's such a big issue to have e.g. a ConvergenceWarning in an example if a few are remaining. That's a real use case, and it's better to show that to user rather than hide it (just for the sake of having no warnings in sphinx log).

@@ -90,7 +90,7 @@ def fit_and_score(estimator, max_iter, X_train, X_test, y_train, y_test):
 # Define the estimators to compare
 estimator_dict = {
    'No stopping criterion':
-    linear_model.SGDClassifier(tol=None, n_iter_no_change=3),
+    linear_model.SGDClassifier(tol=-np.inf, n_iter_no_change=3),


Why not None (or just remove it altogether since it's the default)?

Had it -inf cause that's the default now, but changed to 1e-3 which is the new default. Not passing it causes a warning.

I would argue that it's better to show the convergence warning to user rather than hide it.

My idea here is to be explicit in the code that we know the model is not converging, but we know what we're doing. I'd say if such a usecase happens in production, the user should explicitly have this in the code.

LGTM, though tests are failing.

adrinjalali · 2019-01-02T22:38:46Z

yep, the tests fail due to #12906, they used to pass though.

adrinjalali · 2019-01-17T10:05:09Z

Tests finally pass, [hopefully final] reviews welcome :)

jnothman · 2019-01-17T10:41:23Z

Thanks @adrinjalali

Hmm... this has broken Circle with the following TeX error:


! Package pdftex.def Error: File `modules/../auto_examples/svm/images/sphx_glr_
plot_iris_001.png' not found.

See the pdftex.def package documentation for explanation.
Type  H <return>  for immediate help.

Any idea what the cause is, or does it need investigation?

jnothman · 2019-01-17T12:27:15Z

Ah, I see. File name changed.
