I have tried to use bert model to train on RAFT datasets, the original model went well. But when I tried to add adapter to finetune, it went wrong.

Hi I had the same problem, did you solve it somehow?

3

I also encountered this issue and this thread seems to be the only one about it. Any suggestions are welcome.

Hi,

Were either of you able to solve this problem? I face the same issue when trying to use LoRA for fine-tuning.

5

I am encountering the same error when fine tuning pre trained model when splitting processing between 2 gpus using DataParallel.
Have you found a solution?

6

No facing the same issue while fine tuning the gpt2 model

I have the same problem. For me it’s happening when I am using Trainer with DDP or with accelerate’s multi-gpu trianing. But it only happens when I try to use more than one GPU. If I use CUDA_VISIBLE_DEVICES=0, everything works fine. It seems like a bug in Trainer.

Nothing worked for me.

I added here the following line:

self._signature_columns += list(set(["labels", "input_ids"]))

Don’t think this is the best way to proceed, anyway, it works for me with flan-t5 LoRA training.
