Title: Simple MNIST convnet
Author: [fchollet](https://twitter.com/fchollet)
Date created: 2015/06/19
Last modified: 2020/04/21
Description: A simple convnet that achieves ~99% test accuracy on MNIST.
Modified:
- data wrapped as a Sequence
- addede various prints to trace the processes while multiprocessing
Observations:
- it works for:
- both fit() and fit_generator() if the sequence is thread-safe
- both processes/threads
- all multiprocessing methods
- Keras peeks at the index 0 of the sequence from the main process!
- GeneratorDataAdapter.__init__() - peek_and_restore()
- on_batch_end() is also called from the main process
- otherwise __getitem__ is called from subprocesses
- the are separate processes for training/validation data
- for fork method the subprocesses are reused across epochs
- for forkserver/spawn methods the subprocesses are renew for each epoch
