OSError:无法加载共享对象文件：llvmlite.dll（与形状相关。可能缺少什么？）

Question

我想把SHAP和Anaconda一起使用。 特权： llvmlite已安装：

• pip安装llvmlite 已满足要求：c:\users…\anaconda3\lib\site包中的llvmlite（0.34.0）

但是，我在supject中收到错误消息，即无法加载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()

有人知道根本原因是什么吗？我可以尝试什么

我在尝试导入numba时，在jupyter笔记本电脑中的Windows 10和Python 3.8上遇到了同样的llvmlite缺少DLL的问题，并通过使用pip而不是conda安装解决了这个问题：

conda uninstall llvmlite
pip install llvmlite

如果它仍然无法工作，请尝试通过在此页面上下载控制盘从控制盘安装llvmlite:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#llvmlite
pip install llvmlite-0.34.0-cp38-cp38-win_amd64.whl（更换为车轮）
