您好，我按照github上第三种微调方法，执行以下脚本，但是报错
./scripts/run_finetune_with_lora.sh

--dataset_path data/sft/train
--output_lora_path output_models/finetuned_Qwen1.5-1.8B_lora

Thanks for your interest in LMFlow! We suspect it to be a problem caused by python version and dependency. You may try to use python3.9 and upgrade the peft package via pip install -U peft. We will make corresponding modifications later as well. Thanks for your valuable suggestions 😄

Is it possible that it is because Qwen1.5-1.8B is not yet supported?

pip install -U peft solved. Thanks a lot.
Sorry，I update peft from 0.4.0 to 0.10.0 meet same error.

Is there any library or package on your side that requires python 3.11? We recommend to use python 3.9, since we are developing LMFlow on that version. Python 3.9 works fine for me.
You could try:

git clone https://github.com/OptimalScale/LMFlow.git
cd LMFlow
conda create -n lmflow python=3.9 -y
conda activate lmflow
conda install mpi4py
bash install.sh

And we are working on solving conversation formatter dataclass issue for higher python versions. Sorry for the inconvenience.
