执行cli_demo.py或者web_demo.py，均报错“AttributeError: 'bool' object has no attribute 'encode' ”

init model ...
You are using an old version of the checkpointing format that is deprecated (We will also silently ignore gradient_checkpointing_kwargs in case you passed it).Please update to the new format on your modeling file. To use the new format, you need to completely remove the definition of the method _set_gradient_checkpointing in your model.
Loading checkpoint shards: 100%|██████████████████████████████████████████████████████████████████████████████████████████████████████████████| 3/3 [00:13<00:00, 4.51s/it]
We've detected an older driver with an RTX 4000 series GPU. These drivers have issues with P2P. This can affect the multi-gpu inference when using accelerate device_map.Please make sure to update your driver to the latest version which resolves this.
欢迎使用百川大模型，输入进行对话，vim 多行输入，clear 清空历史，CTRL+C 中断生成，stream 开关流式生成，exit 结束。

用户：你好
