无法在jupyter笔记本中导入模块；错误的系统路径 [英] Cannot import modules in jupyter notebook; wrong sys.path

问题描述

我在iPython/Jupyter笔记本中导入模块时遇到问题.问题从根本上在于sys.path指向的位置.

I am having a problem importing modules in my iPython/Jupyter notebook. The problem fundamentally lies in where the sys.path is pointing to.

在iPython/Jupyter笔记本中，sys.executable返回:

From the iPython/Jupyter notebook, sys.executable returns:

'/usr/bin/python'

但是，它从命令行返回:

However, from the command line, it returns:

'//anaconda/bin/python'

我尝试卸载并重新安装anacondas，但问题仍然存在.

I have tried un-installing and re-installing anacondas, but the problem still remains.

我还尝试在bash_profile中增加$ PYTHONPATH使其包含//anaconda/bin/python，但这无法解决.

I have also tried augmenting $PYTHONPATH in my bash_profile to include //anaconda/bin/python, but this doesn't resolve it.

反正有没有永久地改变jupyter笔记本中的sys.path的地方，而不仅仅是使用sys.path.append(...)?

Is there anyway to change the sys.path in my jupyter notebook permanently, without simply using sys.path.append(...)?

推荐答案

1. 打开一个新的终端窗口，看看是否有帮助.如果不是，请继续执行2.

1. Open a new terminal window and see if this helps. If not, proceed with 2.

从终端启动标准的Python会话，然后输入以下内容:

Start a standard Python session from the terminal and type this:

>>> import sys
>>> sys.executable

在笔记本中执行相同操作:

Do the same in the notebook:

In [1]: import sys
        sys.executable

比较结果.希望这可以为您提供线索.

Compare the results. Hopefully, this gives you a clue what is going on.
