I’m having a really weird issue ever since upgrading to Keras 2.0. I’m using a very basic convolutional neural net and for some reason when using fit_generator() I am unable to get the model to train. But, if i save the outputs from the generators to a bcolz file, and then run model.fit() instead of model.fit_generator(), the model is able to train normally. I am using the default parameters for the generator function, and compiling my model with the Adam optimizer at a learning rate of 1e-4. I’ve been trying to figure this out for well over a day now, and have had no luck. Has this happened to anyone else?
