nteract 使用教程

1. 安装
   
   直接去官网下载 一路回车
   
   官网

2. 建立python虚拟环境 和我们平时一样 不同的是在建立完之后 要安装一个kernel
   
   Using Python3 with pip and a virtual environment

   python3 -m venv my_environment_name      # create a virtual environment
   source my_environment_name/bin/activate  # activate the virtual environment
   python -m pip install ipykernel  -i https://pypi.doubanio.com/simple/         # install the python kernel (ipykernel) into the virtual environment
   python -m ipykernel install
   

   Using Python 2 with pip and a virtual environment

   python -m pip install virtualenv  # install a package for creating virtual environment
   cd my_project_folder              # create a project folder
   virtualenv my_project             # create a virtual environment
   source my_project/bin/activate    # activate the virtual environment
   python -m pip install ipykernel -i https://pypi.doubanio.com/simple/    # install the python kernel (ipykernel) into the virtual environment
   python -m ipykernel install
   

3. 使用这个py环境打开nteract

   # 在环境激活的情况下
   nteract -k python3
   

4. 修改kernel名字，有很多kernel的话，都显示python3会导致分不清哪个是哪个，所以需要修改名字
   
   安装完kernel 屏幕上显示

   ➜ python3 -m ipykernel install
   Installed kernelspec python3 in /usr/local/share/jupyter/kernels/python3
   

   进入这个路径 修改kernel.json 里的display name
