Web1 Answer. Your GridSearchCV is operaing over a RidgeCV object, that's expecting to take a list of alphas, and a scalar of each of the other parameters. However, GridSearchCV does not know that, and is passing it a single parameter at a time from each list, including alphas. When your RidgeCV object gets a scalar for alphas, it tries to take its ...
