Hi Robert, > I do have a .coef_ variable which I believe is the coefficient for the best fit only.
`coef` never existed. Fitted attributes always end with underscore. We do not store coefficients for all fitted `alphas_`. We provide some information regarding the MSE path for all tried alphas: https://scikit-learn.org/stable/auto_examples/linear_model/plot_lasso_model_selection.html > the alphas and alphas_ variables have a similar issue in that alphas returns nothing while alphas_ returns the list of alphas used. You probably created a model such as `model = LasssoCV()`. By default, the parameter `alpha=None` thus accessing it will return None. After fitting, `alphas_` will be automatically created as specified in the documentation. It will correspond to the values tried by cross-validation. If instead, you are passing an array to `alphas` then `alphas_` will be the same as `alphas_` after calling `fit`.
