Currently, the .fit_generator()
method of Keras is not supported by the scikit-learn wrapper also provided by Keras. Without this, there is no way to access this method at the moment, since modAL requires a scikit-learn interface from its estimators.
However, there is a workaround which might help. Before passing your model to the ActiveLearner, you can train it by iterating through the batches in the generator and training manually by calling fit. This would also work with PyTorch models. (And for PyTorch, this is the proper way to train from generator anyway.)
As a sidenote, lately I have been thinking that it would be a good idea to abandon the scikit-learn wrappers and write modAL in a way such that Keras was in the beginning: handling each backend specifically but hiding it from the user, providing a unified API. This of course would be a lot of work, but it would be a logical step in the evolution of modAL.
