The alpha parameter is shared for all problems; If you wnat to use differnt parameters, you probably want to perform seprate fits.

Under these circumstances, how can I adapt this to use individual alpha regularization parameters for each regression? If I use GridSeachCV, I would have to hand over a matrix of possible regularization parameters, or how would that work? Thanks in advance - I have been searching for hours but could not find anything on this topic.
