在 Jupyer Notebook 中找不到来自 Conda env 的包

问题描述

我创建了一个名为 imagescraper 的环境并用它安装了 pip.

I created an environment called imagescraper and installed pip with it.

然后我继续使用 pip 安装一个名为 ImageScraper 的包；

I then proceed to use pip to install a package called ImageScraper;

>>activate imagescraper
[imagescraper]>>pip install ImageScraper

只是为了确保我已经成功安装了包:

Just to ensure that I have the package successfully installed:

>>conda list

[imagescraper] C:UsersJohn>conda list
# packages in environment at C:Anaconda2envsimagescrap

在我启动 Jupyter notebook 之前，只是为了检查我们从哪里获取路径:

Before I launch Jupyter notebook, just to check where we are getting the path from:

[imagescraper] C:UsersJohn>python
Python 2.7.11 |Continuum Analytics, Inc.| (default, Feb 16 2016, 09:58:36) [MSC
v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

>>> import sys
>>> sys.executable
'C:\Anaconda2\envs\imagescraper\python.exe'
>>> import image_scraper

似乎没问题，所以我继续使用启动 Jupyter 笔记本

Seems ok, so I proceed to launch Jupyter notebook using

[imagescraper]>>jupyter notebook

在笔记本中我创建了一本新书，当我尝试相同的时候；

Within the notebook I created a new book and when i tried the same;

import image_scraper

我回来了:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-6c2b65c9cdeb> in <module>()
----> 1 import image_scraper

ImportError: No module named image_scraper

用同样的方法检查 Jupyter notebook 中的路径，我明白了；

Doing the same to check the paths within Jupyter notebook, I get this;

import sys

sys.executable

'C:\Anaconda2\python.exe'

这告诉我它不是指我安装模块的环境.

Which tells me that it is not referring to the environment where I installed the modules in.

有什么方法可以确保我的笔记本都引用它自己的 env 包?

Is there a way I can ensure that my notebooks all refer to its own env packages?

推荐答案

这里有两种可能的解决方案:

Here are two possible solutions:

您可以根据您的 imagescraper 环境注册一个新内核.内核将从 imagescraper 环境开始，因此可以看到它的所有包.

You can register a new kernel based on your imagescraper environment. The kernel will start from the imagescraper environment and thus sees all its packages.

source activate imagescraper
conda install ipykernel
ipython kernel install --name imagescraper

这会将名为 imagescraper 的新内核添加到您的 jupyter 仪表板.

This will add a new kernel named imagescraper to your jupyter dashboard.

另一种解决方案是将 jupyter notebook 安装到 imagescraper 环境中，并从该环境中启动 jupyter.这需要在您启动 jupyter notebook 时激活 imagescraper.

Another solution is to install jupyter notebook into the imagescraper environment and start jupyter from the enviroment. This requires activating imagescraper whenever you start jupyter notebook.

source activate imagescraper
conda install notebook
jupyter notebook
