[Bug] Lora微调内存一直上涨直到Out Of Memory

中文：其他项目中都会增加参数overwrite_cache去释放暴涨的显存，这个项目我加这个参数没用，请问有可能解决吗？
english: in other projects will add parameter overwrite_cache to release the skyrocketing video memory. In this project, it is useless for me to add this parameter. Is it possible to solve this problem?

Hi,

I can't reproduce the bug. I tried with

CUDA_VISIBLE_DEVICES=0 python finetune.py --base_model 'yahma/llama-7b-hf' --data_path 'math_10k.json' --output_dir './trained_models/test/' --batch_size 128 --micro_batch_size 4 --num_epochs 3 --learning_rate 3e-4 --cutoff_len 256 --val_set_size 120 --eval_step 80 --save_step 80 --adapter_name lora --load_8bit --target_modules '["up_proj", "down_proj"]'

the memory used is 18469 MB, and it is not keeping increasing. I used a single 3090 for the testing. Could you inform more information like the command, pytorch version, GPU and so on?

BTW, the argument --overwrite_cache is used for loading cached dataset in [ChatGLM2-6B](https://github.com/THUDM/ChatGLM2-6B/tree/main)/[ptuning](https://github.com/THUDM/ChatGLM2-6B/tree/main/ptuning) /main.py line 234, 253, and 272.

Thanks!
