Reproduction

python pissa_init.py ~/WORKDIR/hf/Qwen2-7B-Instruct ~/WORKDIR/saves/Qwen2-7B/pissa/sft -p 16 --lora_rank 32 --lora_target 'k_proj,o_proj,q_proj,v_proj,down_proj,gate_proj,up_proj'

Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.
`low_cpu_mem_usage` was None, now set to True since model is quantized.

AttributeError: 'tuple' object has no attribute 'split'

打印出来确实传递成元组了
lora_target value before function call: ('k_proj', 'o_proj', 'q_proj', 'v_proj', 'down_proj', 'gate_proj', 'up_proj'), type: <class 'tuple'>

Expected behavior

No response
