NotImplementedError: Cannot copy out of meta tensor; no data!

[greatewei]

想要在原来的lora基础上进行数据增量训练，data.json有3000条左右数据 运行命令：

python finetune.py \
--data_path /data/chat/Chinese-Vicuna/data/data.json \
--output_path /data/chat/models/llama_lora/llama-7b-yy-lora \
--model_path /data/chat/models/llama_base/llama-7b-hf  \
--eval_steps 200 \
--save_steps 200 \
--test_size 1 \
--resume_from_checkpoint /data/chat/models/llama_lora/Chinese-Vicuna-lora-7b-belle-and-guanaco \
--ignore_data_skip True

错误内容：

求大佬帮忙看看
