我刚刚在我的笔记本电脑上使用IPython
安装了pip
3.0,该笔记本正在运行Ubuntu
14.04:
$ pip search ipython
ipython-cluster-helper - Simplify IPython cluster start up and use for
multiple schedulers.
ipython - IPython: Productive Interactive Computing
INSTALLED: 3.0.0 (latest)
然而,当我使用IPython
时,终端似乎认为它使用的是1.2.1版本:
$ ipython
Python 2.7.6 (default, Mar 22 2014, 22:59:38)
Type "copyright", "credits" or "license" for more information.
IPython 1.2.1 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.

更糟糕的是,当我在IPython
3.0支持的JSON nbformat版本4中打开笔记本时,我收到以下错误:
Unreadable Notebook: Unsupported JSON nbformat version 4 (supported version: 3)
我尝试使用IPython
小组推荐的命令将笔记本降级到版本3,但这对我来说也失败了:
$ ipython nbconvert --to notebook --nbformat 3 1-intro-to-brian-neurons.ipynb
. . .
[NbConvertApp] CRITICAL | Bad config encountered during initialization:
[NbConvertApp] CRITICAL | Unrecognized flag: '--nbformat'
这里发生了什么?
答案 0 :(得分:2)
以前使用IPython
安装了旧版apt-get
。使用apt-get remove ipython
删除旧版本。
答案 1 :(得分:0)
jupyter nbconvert --to notebook --nbformat=3 <file.ipynb>
为我工作。
我的本地anaconda2支持版本4但是docker的ipython不支持。
