下载 Anaconda3安装包，并执行安装命令：
bash Anaconda3-2019.07-Linux-x86_64.sh
确定安装并初始化：
Do you wish the installer to initialize Anaconda3 by running conda init? [yes|no] [no] >>> yes
安装完Anaconda3后用conda命令安装jupyterlab：
conda install jupyterlab
需要用ipython命令生成秘钥，启动ipython：
ipython
执行命令生成秘钥：
In [1]: from notebook.auth import passwd In [2]: passwd() Enter password: Verify password: Out[2]: 'sha1:f704b702aea2:01e2bd991f9c7208ba177b46f4d10b6907810927'
产生jupyterlab配置文件：
jupyter lab --generate-config
修改配置文件：
vi /root/.jupyter/jupyter_notebook_config.py
更改内容如下：
# 将ip设置为*，意味允许任何IP访问 c.NotebookApp.ip = '*' # 这里的密码就是上边我们生成的那一串 c.NotebookApp.password = 'sha1:f704b702aea2:01e2bd991f9c7208ba177b46f4d10b6907810927'
# 服务器上并没有浏览器可以供Jupyter打开
c.NotebookApp.open_browser = False
# 监听端口设置为8888或其他自己喜欢的端口
c.NotebookApp.port = 8888
# 允许远程访问
c.NotebookApp.allow_remote_access = True
接下来输入jupyter lab启动jupyter服务即可：
jupyter lab --allow-root
返回如下信息：

打开页面查看：
直接点击“Log in”登录主界面：
解释：Ipython把输入的密码转换成sha，并用于认证JupyterLab，本文在Ipython输入密码和确认密码时直接回车，相当于不设密码，因此登录JupyterLab时可以不输入密码直接点击登录。
安装好Tensorflow：
安装好Keras：
查找site-packages文件目录：
find / -name 'site-packages' -type d
经比较排除，确定具体地址为：
/root/anaconda3/lib/python3.7/site-packages
下载mnist.npz数据，修改mnist.py文件，参考： https://www.cnblogs.com/ratels/p/11144881.html 和 https://www.cnblogs.com/shinny/p/9283372.html ，如下：
复制并执行CNN代码，参考：https://www.cnblogs.com/ratels/p/11144881.html
服务器相比便携本速度提高了不少，平均每个Epoch的训练时间由7s缩短到4s。
复制并执行Seq2Seq代码，参考：https://www.cnblogs.com/ratels/p/11192045.html
服务器相比便携本速度提高了不少，平均每个Epoch的训练时间由140s缩短到57s。
