Xlora cannot reload model from last checkpoint by using trainer.train(resume_from_checkpoint="checkpp")

[SongHanKen]

System Info

Peft v0.13.2
Transformers v4.44.0
Accelerate v0.33.0

Who can help?

Since this relates to an interaction with PEFT and Xlora maybe @BenjaminBossan @EricLBuehler

Reproduction

Hi there,
I try to use trainer.train(resume_from_checkpoint=checkpoint_directory) or trainer.train(resume_from_checkpoint="YES") to reload(retrain) the model with Xlora from the last checkpoint, here is my training code and base model is chatglm4-9b:

Expected behavior

I expect the training to resume from the last checkpoint, continuing from the saved state without reinitializing the model weights, optimizer states, or any training progress by using resume_from_checkpoint. When training with lora, I successfully saved several checkpoints and could resume training from these checkpoints without any issues. However, with xlora, although I am able to save checkpoints during training, I encounter issues when trying to resume training from these checkpoints. The model fails to load properly, preventing the continuation of training from the saved state. Here is bug information:

/home/zhangjunyi/anaconda3/lib/python3.11/site-packages/transformers/trainer.py:3098: FutureWarning: You are using `torch.load` with `weights_only=False` (the current default value), which uses the default pickle module implicitly. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). In a future release, the default value for `weights_only` will be flipped to `True`. This limits the functions that could be executed during unpickling. Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via `torch.serialization.add_safe_globals`. We recommend you start setting `weights_only=True` for any use case where you don't have full control of the loaded file. Please open an issue on GitHub for any issues related to this experimental feature.

I would greatly appreciate any guidance on resolving this issue with xlora checkpoint restoration. If anyone has encountered a similar problem or has insights into specific settings or steps to enable successful checkpoint recovery for xlora, your advice would be invaluable. Additionally, if any maintainers or community members familiar with xlora could offer support, that would be extremely helpful. Many thanks
