Add support for model training from checkpoint #36

Open Littleor opened 1 year ago

Littleor commented 1 year ago

This pull request adds support for model training continuation from a checkpoint, making it possible to resume the training process at a later point in time.

NOTE: Please note that this pull request adds support for model training from a checkpoint because the previous pull request (#23) did not work properly in my environment.

To utilize this feature, simply include the --ckpt parameter, such as:

torchrun --nnodes=1 --nproc_per_node=N train.py --model DiT-XL/2 --data-path /path/to/imagenet/train --ckpt /path/to/model.pt

Hi @Littleor I met a cuda-out-of-memory error after loading from a checkpoint before training. Do you have any idea why this happened? Training from scratch is ok.
