DCGAN实现

参考PyTorch 教程DCGAN，在Jupyter notebook上实现；

1. 环境配置

1.1 Anaconda&Jupyter Notebook安装

• conda create -n tf_py36 python=3.6 创建环境
• source activate tf_py36 激活环境
• Install ptorch， torchvision 请参考官网
• pip install jupyter 安装Jupyter

1.2 远程访问Jupter notebook

参考GPU云服务器配置

• ssh 连接远程服务器，激活虚拟环境tf_py36
• jupyter notebook的配置： 需要生成jupyter notebook配置文件

 jupyter notebook --generate-config
 Writing default config to: /home/cyli/.jupyter/jupyter_notebook_config.py

• 调用ipython (或python)设置jupyter notebook密码

(tf_py36) cyli@ubuntu:/home/cyli$ ipython
Python 3.6.2 |Continuum Analytics, Inc.| (default, Jul 20 2017, 13:51:32)

In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password: 
Verify password: 
Out[2]: 'sha1:b804cd47ff66:7c1d4a54809c54c356ae406b05c4c50767cc7958'
In [3]: exit

记录下’sha1:b804cd47ff66:7c1d4a54809c54c356ae406b05c4c50767cc7958’，在文件配置时候要用。
配置jupyter notebook的config文件，同时记录自己所输入的密码。

• 取消激活

source deactivate tf_py36
cyli@ubuntu:~$

• 修改配置

cyli@ubuntu:~$ vi /home/cyli/.jupyter/jupyter_notebook_config.py

• 修改如下

c.NotebookApp.ip = '*'
c.NotebookApp.password = 'sha1:b804cd47ff66:7c1d4a54809c54c356ae406b05c4c50767cc7958'
c.NotebookApp.open_browser = False                                       

• 在项目文件夹下启动jupyter notebook

cyli@ubuntu:/media/sdc/cyli/tus/dcgan_pytorch001$ jupyter notebook
