I have pretty simple model
model.compile(optimizer = 'adam', loss=bce_jaccard_loss, metrics=[iou_score]) history = model.fit_generator(training_generator, shuffle =True, epochs=epochs, workers=4, use_multiprocessing=True, validation_data=(x_val, y_val), verbose = 1)
However after training doesnt have learning rate history, even model doesnt have stored optimizer (no
history.history.keys() dict_keys(['val_loss', 'val_iou_score', 'loss', 'iou_score'])
How to get learning rate history?
PS Sometimes I have it in history.history but now not - what can affect that?
