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)
