This problem has to do with incompatibility of the notebook and your IPython version. In my current version of IPython:
这个问题与笔记本和你的 IPython 版本不兼容有关。在我当前的 IPython 版本中：
ipython --version
2.3.1
When I try to open the file (FunIT\ experiment.ipynb):
当我尝试打开文件 (FunIT\experiment.ipynb) 时：
ipython notebook FunIT\ experiment.ipynb
I get the following error message
我收到以下错误消息
Error loading notebook
Unreadable Notebook: FunIT experiment.ipynb Unsupported nbformat version 4
加载笔记本时出错
不可读的笔记本：FunIT Experiment.ipynb Unsupported nbformat version 4
The error message indicates that the notebook format is not supported. Let's install the development version, https://github.com/ipython/ipython. I used virtual Environment, http://docs.python-guide.org/en/latest/dev/virtualenvs/, but it's not necessary.
错误消息表明不支持笔记本格式。让我们安装开发版本，https://github.com/ipython/ipython。我使用了虚拟环境，http://docs.python-guide.org/en/latest/dev/virtualenvs/，但这不是必需的。
Install virtual environment
安装虚拟环境
pip install virtualenv
mkdir test
cd test
virtualenv venv
source venv/bin/activate
Ipython Notebook development installation
ipython Notebook开发安装
git clone --recursive https://github.com/ipython/ipython.git
cd ipython
pip install -e ".[notebook]" --user
Now I have the current development version.
现在我有了当前的开发版本。
ipython --version
3.0.0-dev
And I can open the file with ipython notebook
我可以用 ipython notebook 打开文件
ipython notebook FunIT\ experiment.ipynb
Here is a snippet of the code:
这是代码的一个片段：
import pandas as pd
import numpy as np
from pandas.tools.pivot import pivot_table
#from sklearn.metrics import roc_auc_score
import matplotlib.pyplot as plt
%pylab inline
#from sklearn.neighbors.kde import KernelDensity
import seaborn as sns
import scipy.stats as st
sns.set()
