318938278  by Andre Araujo:

    Loading pretrained ImageNet weights to initialize the ResNet backbone. Changed the defaults of the batch size and initial learning rate to increase convergence on the GLDv2 dataset. Made the evaluation batch size dynamic depending on the global batch size.

--
318911740  by Andre Araujo:

    Introduced additional shuffling of the TRAIN and VALIDATION datasets to ensure label variance across batches.

--
318908335  by Andre Araujo:

    Export model migration to TF2.

--
318489123  by Andre Araujo:

    Model exporting script for global feature trained with DELF codebase.
    Additionally, makes a small change to replace back_prop=False in the tf.while_loop call (see deprecation notice in https://www.tensorflow.org/api_docs/python/tf/while_loop

).
