Jupyter 笔记本 xgboost 导入

Question

I have the problem below (I'm on a MAC)

I can import xgboost from python2.7 or python3.6 with my Terminal but the thing is that I can not import it on my Jupyter notebook.

import xgboost as xgb

ModuleNotFoundError Traceback (most recent call last) in () ----> 1 import xgboost as xgb

ModuleNotFoundError: No module named 'xgboost'

Although I write :

!pip3 install xgboost

It prints that :

Requirement already satisfied: xgboost in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/xgboost-0.6-py3.6.egg Requirement already satisfied: numpy in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from xgboost) Requirement already satisfied: scipy in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from xgboost)

Help please I searched everywhere :(

Answer 1

Within Jupyter Notebook cell, try running:

import sys !{sys.executable} -m pip install xgboost

This allows the package to be install with right on Jupiter notebook

Answer 2

Running a shell escape !pip3 doesn't guarantee that it will install in the kernel you are running. Try:

import sys
print(sys.base_prefix)

and see if this matches either of your terminal pythons. You should be able to run <base_prefix>/bin/pip install <package> to ensure it is in the right site-packages .

You can also look at which python your kernel is running by looking in kernel.json most likely in ~/Library/Jupyter/kernels/<kernel>/kernel.json .

Note: you can also programmatically install packages with:

import pip
pip.main(['install', '<package>'])

which will force it to be in the right site-packages for your kernel.
