@h?ken-lidis right. There are probably several versions of python. So to install your package to python where your jupyteris located:
@h?ken-lid是对的。可能有几个版本的python。因此，要将您的软件包安装到您所在的python jupyter：
$ which jupyter
/YOURPATH/bin/jupyter
$ /YOURPATH/bin/pip install scipy
This will do for Python 2.x
这适用于Python 2.x
For Python 3.xpip3will be in /YOURPATH/bininstead of single pip
对于Python 3.xpip3将在/YOURPATH/bin而不是单个pip
回答by H?ken Lid
You can run pip from python.
您可以从 python 运行 pip。
import pip
pip.main(['install', 'scipy'])
If you are using the system python, and running jupyter in a process that doesn't have permission to install global packages, you can use the --userflag to install a module for the current user only.
如果您使用系统 python，并且在没有权限安装全局包的进程中运行 jupyter，则可以使用该--user标志仅为当前用户安装模块。
pip.main(['install', '--user', 'scipy'])
