 * `VALIDATION_STEPS` and `STEPS_PER_EPOCH` are now forced to depend on the dataset size, hardcoded.
 * `multiprocessing=False`, hardcoded.
 * [@John1231983]'s changed from [this PR](https://github.com/killthekitten/kaggle-ds-bowl-2018-baseline/pull/1).
+* Added `RESNET_ARCHITECTURE` variable to the config (`resnet50` or `resnet101` while 101 comes with a default config).
