Vision Transformer Autoencoder (ViT AE)

This repository contains a distributed training setup for a grayscale image autoencoder based on a Vision Transformer (ViT) backbone. It supports SLURM-based multi-GPU training using PyTorch DDP and includes modular components for model, data loading, configuration, and training management.
