To avoid blocking computation code with data loading, PyTorch provides an easy switch to perform multi-process data loading by simply setting the argument num_workers to a positive integer. Single-process data loading (default)

The size of dataloader differs slightly for different GPUs, leading to different configs.val_steps for different GPUs. So some GPUs jump into the if statement while others don't. Unify configs.val_steps for all GPUs, and the problem is solved. – Zhang Yu new henderson library
