It seems to be working for binary classification and for multiclass when multi_class='ovr'. I'm having a hard time figuring out the intricacies of multi_class='multinomial'. * Changed default to None for l1_ratio. added warning message is user sets l1_ratio while penalty is not elastic-net * Some more doc * Updated example to plot elastic net sparsity * Fixed flake8 * Fixed test by not modifying attribute in fit * Fixed doc issues * WIP * Partially fixed logistic_reg_CV for multinomial. Also added some comments that are hopefully clear. Still need to fix refit=False * Fixed doc issue * WIP * Fixed test for refit=False in LogisticRegressionCV * Fixed Python 2 numpy version issue * minor doc updates * Weird doc error... * Added test to ensure that elastic net is at least as good as L1 or L2 once l1_ratio has been optimized with grid search Also addressed minor reviews * Fixed test * addressed comments * Added back ignore warning on tests * Added a functional test * Scale data in test... Now failing * elastic-net --> elasticnet * Updated doc for some attributes and checked their shape in tests * Added l1_ratio dimension to coefs_paths and scores attr * improve example + fix test * FIX incorrect lagged_update in SAGA * Add non-regression test for SAGA's bug * FIX flake8 and warning * Re fixed warning * Updated some tests * Addressed comments * more comments and added dimension to LogisticRegressionCV.n_iter_ attribute * Updated whatsnew for 0.21 * better doc shape looks * Fixed whatnew entry after merges * Added dot * Addressed comments + standardized optional default param docstrings * Addessed comments * use swapaxes instead of unsupported moveaxis (hopefully fixes tests) **NOTE:** This service has been marked for deprecation: https://developer.github.com/changes/2018-04-25-github-services-deprecation/ Functionality will be removed from GitHub.com on January 31st, 2019.
