To recover the enn sampler for ResNet-50, we can use `make_enn_sampler_from_checkpoint` (from `enn/checkpoints/utils.py`) which takes the checkpoint and also the number of sample logits we want per image (`num_enn_samples`). Here we set `num_enn_samples=1`, as having `num_enn_samples \u003e 1` just results in multiple similar sample logits per input image."
