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

Question

I want to use SHAP with Anaconda. Prequisites: llvmlite is installed:

• pip install llvmlite Requirement already satisfied: llvmlite in c:\users...\anaconda3\lib\site-packages (0.34.0)

However, I get the error message in the supject, that llvmlite.dll could not be loaded:

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

Does anybody have an idea what the root cause may be and whatelse I could try?

I had the same llvmlite missing DLL issue on Windows 10 with Python 3.8 in jupyter notebook when trying to import numba and solved it by installing with pip instead of conda :

conda uninstall llvmlite
pip install llvmlite

If it still does not wortk try installing llvmlite from wheel by downloading your wheel on this page :
https://www.lfd.uci.edu/~gohlke/pythonlibs/#llvmlite
pip install llvmlite-0.34.0-cp38-cp38-win_amd64.whl (replace with your wheel)
