报错TypeError: Couldn't cast array of type list<item: string> to null

[xxcoco763]

服务器没办法链接huggingface，只是将pred.py中THU/Longbench的路径换成了本地的/home/eval/LongBench/data,config文件中的模型路径也已经添加，报错如下
CUDA_VISIBLE_DEVICES=7 python pred.py --model llama2-13b-chat-16k

The above exception was the direct cause of the following exception:

请问如何解决呢

如果已经将LongBench的data/下载到了本地，可以用如下方式读入文件以载入数据集：将pred.py中第166行改为：

data = [json.loads(line) for line in open(f"LongBench/data/{dataset}.jsonl", encoding="utf-8")]
