finetune error about model size

Skylight-Lark commented 6 months ago

Issue Title: use the finetune script but meet error

Environment

Platform: Ubuntu Linux
GPU: A5000 x 8
Torch Version: 2.1.2

Transformers Version: 4.41.0.dev0

Issue Description

when i used the llava-pp codebase and the finetune script to finetune our model, it appeared that :

Error(s) in loading state_dict for Sequential : size mismatch for 0.weight: copying a param with shape torch.Size([4096, 3072]) from checkpoint, the shape in current model is torch.Size([0]).
    size mismatch for 0.bias: copying a param with shape torch.Size([4096]) from checkpoint, the shape in current model is torch.Size([0]).
    size mismatch for 2.weight: copying a param with shape torch.Size([4096, 4096]) from checkpoint, the shape in current model is torch.Size([0]).
    size mismatch for 2.bias: copying a param with shape torch.Size([4096]) from checkpoint, the shape in current model is torch.Size([0]).

but when i use the llava official codebase and script , i didn't meet that error, which is weird! it seems that the deepspeed zero3 has some bug and can't gather the sharded parameters.

I've tried various approaches in the deepspeed issues and transformers issues to fix this issue but haven't been successful. Any help would be greatly appreciated!

Hi @Skylight-Lark

Thank you for your interest in our work. I notice another person also faced the same error, however not yet sure about what causing it. Could you please try using zero3.json or zero2.json instead of zero3_offload.json and see if it solves the issue?

Thank You

Hi @mmaaz60 Thank you for your quick response. when i use the zore3.json , it also has the same problem. And when using the zero2.json, it will OOM.

Hi @Skylight-Lark

May I know which deepspeed version are you using? Try to use version 0.13.1 and it may help. Further in llava_arch.py, moving the mm_projector initialization code outside for loop may help as well.

Hi @mmaaz60

it works when moving the mm_projector initialization code outside for loop. Thank you for your patience in solving the issue.

Hi, I encountered the same issue while fine-tuning LoRA. Could you please share your solution if possible?
