Keras have very little info about keras.utils.Sequence, actually the only reason I want to derive my batch generator from keras.utils.Sequence is that I want to not to write thread pool with queue by myself, but I'm not sure if it's best choice for my task, here is my questions:. What should __len__ return if I have random generator and I don't have any predefined 'list' with samples.

20.05.2018 · From here, you have two options. I would recommend updating Keras, pip install keras --upgrade, you'll then have no issues importing the keras.utils.Sequence Alternatively, based off this issue #3726, it looks as though Sequence used to be in the Preprocessing module in previous versions, so following those steps worked for me when testing your issue.

31.12.2021 · Compat aliases for migration. See Migration guide for more details. tf.compat.v1.keras.utils.Sequence. Every Sequence must implement the __getitem__ and the __len__ methods. If you want to modify your dataset between epochs you may implement on_epoch_end . The method __getitem__ should return a complete batch.
