Jupyter Notebook
搭建python2和python3共存的环境！
安装python和python-pip
--这个非常关键,注意ipython3和ipython, pip与pip3, python与python3
sudo apt-get install ipython3 python-cycler-doc dvipng ffmpeg inkscape python3-cairocffi python3-nose python3-pyqt4 python3-scipy python3-sip python3-matplotlib
$ pip install --upgrade pip //更新pip$ pip3 install --upgrade pip安装jupyter-notebook
$ pip install jupyter
$ pip3 install jupyter 配置可以同时使用python2和python3内核
(ipython和ipython3是上面安装的)
$ ipython kernel install--user$ ipython3 kernel install --user$ python3 -m ipykernel install--user$ python2 -m ipykernel install--user$ pip install -U ipykernel$ jupyter-notebook 
tkinter # If this fails your Python may not be configured for Tk解决方法
安装tk
>> sudo apt install python3-tk (Ubuntu)
>> yum install python3-tk (Centos)
安装tk开发类库:
>> sudo apt install tk-dev (Ubuntu)
>> yum install tk-devel (Centos)
