- The parameter `n_alphas ` has been deprecated in the following classes:
2
- :class: `linear_model.ElasticNetCV ` and :class: `linear_model.LassoCV `
3
- and :class: `linear_model.MultiTaskElasticNetCV `
4
- and :class: `linear_model.MultiTaskLassoCV `, and will be removed in 1.9. The parameter
5
- `alphas ` now supports both integers and array-likes, removing the need for `n_alphas `.
6
- From now on, only `alphas ` should be set to either indicate the number of alphas to
7
- automatically generate (int) or to provide a list of alphas (array-like) to test along
8
- the regularization path.

- - In :mod: `utils.estimator_checks ` we now enforce for binary classifiers a
2

3
