我想在Anaconda中使用SHAP。先决条件：已安装llvmlite：
- pip install llvmlite已满足要求：llvmlite已安装在c:\users…\anaconda3\lib\site-packages (0.34.0)
然而，我收到了主题中的错误消息，无法加载llvmlite.dll：

回答：
我在Windows 10上使用Python 3.8的jupyter笔记本时，尝试导入numba时也遇到了同样的llvmlite缺少DLL的问题，通过使用pip而不是conda安装解决了这个问题：
conda uninstall llvmlitepip install llvmlite如果还是不行，可以尝试从这个页面下载适合你的wheel文件来安装llvmlite：
https://www.lfd.uci.edu/~gohlke/pythonlibs/#llvmlitepip install llvmlite-0.34.0-cp38-cp38-win_amd64.whl （替换为你下载的wheel文件）
