OSError：无法加载共享对象文件：llvmlite.dll与SHAP相关可能丢失什么？

如何解决OSError：无法加载共享对象文件：llvmlite.dll与SHAP相关可能丢失什么？

我想将SHAP与Anaconda一起使用。 先决条件： llvmlite已安装：

• pip安装llvmlite 已经满足要求：c：\ users ... \ anaconda3 \ lib \ site-packages（0.34.0）中的llvmlite

但是，我在错误提示中收到错误消息，提示无法加载llvmlite.dll：

from sklearn.model_selection import train_test_split

import xgboost

import shap

import numpy as np

import matplotlib.pylab as pl

​
# print the JS visualization code to the notebook

shap.initjs()

有人知道根本原因可能是什么，我还能尝试什么？

解决方法

当尝试导入numba并通过使用pip而不是conda进行安装来解决该问题时，在jupyter笔记本中使用python 3.8的Windows 10上，我在llvmlite缺少DLL的问题相同：

conda uninstall llvmlite
pip install llvmlite

如果仍然无法正常运行，请尝试通过在此页面上下载车轮从车轮安装llvmlite：
https://www.lfd.uci.edu/~gohlke/pythonlibs/#llvmlite
pip install llvmlite-0.34.0-cp38-cp38-win_amd64.whl（用轮子代替）
