python3 + tensorflow+zeppelin

1. Installing with virtualenv
   nohup jupyter notebook > /dev/null 2>&1 &
   trick：
   import sys
   sys.executable
   如何切换到virtualenv ？ pip install ipykernel && python -m ipykernel install --user --name [环境名] --display-name [简称]

设置密码：

1).  浏览器打开jupyter，新建一个python文件，第一行输入：`from notebook.auth import passwd`
2).  shift+enter执行命令并进入下一行。下一行输入：`passwd()` ，回车后提示输入密码，输入两次。
3).  哈希密码`sha1:xxxxx`
4).  再次打开`配置文件jupyter_notebook_config.py`,找到`c.NotebookApp.password`=第三步的哈希密码，重启`jupyter notebook`即可

pip3 install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.6.0-py3-none-any.whl

蛋疼的版本问题：https://www.jianshu.com/p/1a3e194886b4
目前tensorflow对python 3.7支持不好，建议使用python3.6或者python3.5

2.安装pyh模块

3.python2 到 python3 踩坑
tips：
（1）dict 没有has_key函数；用 key in dict 判断，并且dict.keys()返回类型需要强制转成list再排序，即list(dict.keys())
（2）map函数，python2中直接返回结果，而python3中返回的是map对象, 需要list转化；注意如果不在map前加list，lambda函数根本不会执行~ ~蛋疼
4、zeppelin使用说明

5、matplotlib问题
