OSError: Could not load shared object file: llvmlite.dll (SHAP related. What could be missing?)

Question

我想在 Anaconda 中使用 SHAP。先决条件： llvmlite 已安装：

pip 安装 llvmlite 要求已满足：c:\users 中的 llvmlite...\anaconda3\lib\site-packages (0.34.0)

但是，我在主题中收到错误消息，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()

OSError: Could not load shared object file: llvmlite.dll

有没有人知道根本原因可能是什么以及我还可以尝试什么？

谢谢，马库斯

Answer 1

我在 jupyter notebook 中尝试导入 numba 时在 Windows 10 和 Python 3.8 上遇到了相同的 llvmlite 缺少 DLL 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

如果仍然无法解决问题，请尝试通过在此页面下载您的 wheel 从 wheel 安装 llvmlite :
https://www.lfd.uci.edu/~gohlke/pythonlibs/#llvmlite
pip install llvmlite-0.34.0-cp38-cp38-win_amd64.whl（换成你的轮子）

Answer 2

就我而言，以下操作有效：
conda uninstall llvmlite
然后
conda install llvmlite

Answer 3

我都做了

conda uninstall llvmlite
pip install llvmlite

和

conda uninstall llvmlite
conda install llvmlite

但无法正常工作。

我得到了

conda install -c numba numba
conda install -c numba llvmlite
