WebFor stochastic solvers (sgd, adam), note that this determines the number of epochs (how many times each data point will be used), not the number of gradient steps. (in one case it does the step with a gradient of 0 and in the other it skips TL;DR: You could specify a grid of alpha and n_iter(or max_iter) and use parfit for hyper-optimization on SGDClassifier. Removing this column solves the error, although I'm not sure why as there are no operations being carried out on that column.
