ipynb文件转html

1. ipynb文件转HTML格式导出(不是file -> download as html)
   格式：
   jupyter nbconvert --to html --template basic filename.ipynb
   例子：
   D:\codeworkplace\jupyter-notebook>jupyter nbconvert mnist手写数字版.ipynb
   [NbConvertApp] Converting notebook mnist手写数字版.ipynb to html
   [NbConvertApp] Writing 366487 bytes to mnist手写数字版.html
2. 最后到该目录下找到html文件
