Solve the problem that jupyter cannot import new packages

It mainly introduces the perfect solution jupyter Unable to import The problem with the new package , It has a good reference value , I hope that's helpful . Follow together

Xiaobian, come and have a look

jupyter Because it's in python There is a more humanized design under the framework , Thus in data analysis ,python teaching , as well as python Shine in your fast learning .

jupyter As a person similar to spyder A compiler for , It is beautiful and practical , And it's easy to blog to attract me .

But because of jupyter When writing code in mode , You will find it through pip install package Command line installation package When it's done , Cannot be in jupyter In mode

import package, This has been very confused , Go through all kinds of google, Still can't find the reason , Or it seems that everyone doesn't think it's a thing at all , therefore , I'm here first

Make a note , So as not to forget later

jupyter Practical in mode python Compilation path and other modes python The compilation path is different

stay jupyter In mode , Use sys Introspective mode of package , Find your own compilation path ....( For a long time , I found this thing )

[1] import sys

[2] sys.path

['',

'/home/zhangll/anaconda3/envs/ipykernel_py3/lib/python36.zip',

'/home/zhangll/anaconda3/envs/ipykernel_py3/lib/python3.6',

'/home/zhangll/anaconda3/envs/ipykernel_py3/lib/python3.6/lib-dynload',

'/home/zhangll/anaconda3/envs/ipykernel_py3/lib/python3.6/site-packages',

'/home/zhangll/anaconda3/envs/ipykernel_py3/lib/python3.6/site-packages/IPython/extensions',

'/home/zhangll/.ipython']

Output results can be found ,jupyter In mode python The compiler path of is the same as Python Other compiler paths are completely different .

jupyter The default compilation path is anaconda3/enves Under the table of contents ,

But the original python The default path is

['',

'/home/zhangll/anaconda3/lib/python36.zip',

'/home/zhangll/anaconda3/lib/python3.6',

'/home/zhangll/anaconda3/lib/python3.6/lib-dynload',

'/home/zhangll/anaconda3/lib/python3.6/site-packages',

'/home/zhangll/anaconda3/lib/python3.6/site-packages/Sphinx-1.5.6-py3.6.egg',

'/home/zhangll/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg']

therefore , Through termial/shell Mode is installed in python The default path , Therefore, you need to use the command mode

$ cd /home/zhangll/anaconda3/envs/ipykernel_py3/bin

$ ./pip install package

In order to jupyter Under normal use

Of course, you can modify shell To modify the configuration of the command path pip command

Supplementary knowledge ： repair

take jupyter Put it into your new environment discharge In the new environment pip install jupyter after , Input

python -m ipykernel install --user --name= Environment name is enough
