遇到一个很奇怪的问题

代码:
reranker = BCERerank(model="./bce-reranker-base_v1", top_n=5, device='cuda:0')

错误信息:

ValueError Traceback (most recent call last)

langchain对reranker的支持不如llamaindex，所以集成进langchain的reranker接口由BCEmbedding这个python包提供，解决方案：
1、你需要安装本repository：pip install BCEmbedding==0.1.3
2、按照这个样例来调用：https://github.com/netease-youdao/BCEmbedding?tab=readme-ov-file#1-used-in-langchain

langchain对reranker的支持不如llamaindex，所以集成进langchain的reranker接口由BCEmbedding这个python包提供，解决方案： 1、你需要安装本存储库：pip install BCEmbedding==0.1.3 2、按照这个样例来调用：https://github.com/netease-youdao/BCEmbedding?tab=readme-ov-file#1-used-in-langchain

我使用的就是这段样例,同时也安装了相关的依赖包. 似乎是我的环境导致的,前一天还没报错
