无法在Jupyter笔记本中导入numpy

问题描述

我是iPython / Jupyter的新手。 Python技能有限，但学习。我正在尝试将numpy导入为np并获得以下内容：

I am new to iPython/Jupyter. Python skills limited, but learning. I am trying to import numpy as np and get the following:

我的Mac上安装了几个python，其中有Yosemite，包括Canopy和Anaconda。我希望我的Jupyter笔记本能够使用Anaconda安装，包括与之相关的所有模块，库等。然而，似乎jupyter正在瞄准Canopy。因此，我认为我的问题可能源于错误的联系。

I have several python installs on my Mac, which has Yosemite, including Canopy and Anaconda. I want my Jupyter notebook to use the Anaconda install including all the modules, libraries, etc. associated with it. It seems however that jupyter is targeting Canopy instead. Thus, I think my problem might stem from the wrong linkage.

问题1 ：我的结论是否有效？如果不是，我可能会缺少什么？

QUESTION 1: Does my conclusion hold water? If not, what might I be missing?

问题2 ：我如何指导/链接jupyter与Anaconda而不是Canopy，以便我只从anaconda导入所有东西？

QUESTION 2: How can I direct/link jupyter with Anaconda and not with Canopy so that I import everything from anaconda only?

感谢大家的帮助！

推荐答案

您可以通过运行以下命令将PATH设置为从〜/ anaconda / bin目录执行python命令，方法是将其添加到.bah_profile。

You can either set the PATH to execute python commands from the ~/anaconda/bin directory by prepending it to your .bah_profile by running the following command.

export PATH="/Users/jmmiii/anaconda/bin:$PATH"

或者，您可以通过编辑〜/ .bash_profile并添加：

OR, you can create an alias for the command by editing your ~/.bash_profile and adding:

alias jupyter-notebook="/Users/jmmiii/anaconda/bin/jupyter-notebook"
