可以直接看 ‘解决方法’ 这块

系统配置

我的系统是 win10专业版、Python 3.11.9

问题过程

pip install sentence_transformers安装成功
但是运行代码后报错：

可以看到terminal提示需要 pip install flash_attn
于是我继续pip install flash_attn
报错

解决方法

步骤一：
安装CUDA Toolkit以及cuda：
在cuda官网的下载页面选择匹配自己系统的CUDA Toolkit进行无脑安装
步骤二：
指定 sentence-transformers版本安装
pip install sentence-transformers==2.2.0
