embedding_model_name设置已下载好的text2vec-large-chinese路径，怎么不对呢

[sunyclj]

设置embedding_model_name = './text2vec-large-chinese'，运行create_knowledge.py代码，提示
No sentence-transformers model found with name ./text2vec-large-chinese Creating a new one with MEAN pooling.
text2vec-large-chinese模型文件是从huggingface(https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main)上下载的；
请问是什么原因呢？
