lesson7-superres-gan.ipynb notebook, after you save the gan learner and try to load it again, there is an error:
AttributeError: Can't pickle local object 'gan_loss_from_func.<locals>._loss_G'
I looked in the code and couldn’t find if the GANTrainer saved the generator and critic weights during the training process. Should we save the weights for each network manually? How can the GAN Learner load its weights, especially with custom loss functions?
