通过Google Colab进行x11转发 [英] x11 forwarding through Google Colab

问题描述

我希望x11转发能够在Google Colab上工作.我使用的是Windows 10计算机，可在文章底部找到Google Colab OS信息.这是我进行测试的方法:

1. 安装

   检查

   1. Google Colab不会在代码单元之间保留环境变量.因此，您应该为每个变量设置DISPLAY变量.
   2. Xming可能不允许将远程连接作为默认设置.至少，VcXsrv可以做到这一点.尝试禁用访问控制.这是一个不安全的选择.
   3. 路由器和防火墙必须打开6000 + n/tcp端口.n是从0开始计数的显示编号(例如，主机名:0.0→n = 0)

   I was hoping to get x11 forwarding to work on Google Colab. I am using a Windows 10 machine and the Google Colab OS information can be found at the bottom of the post. Here's what I did to test it out:

   1. Installed Xming and ran it.

   2. Made a new IPython notebook in Google Colab and installed x11 apps successfully using

      !sudo apt-get install x11-apps
      

   3. Set my display to be my IP address using

      !export DISPLAY=<my-ip-address>
      

   4. Run !xeyes. I get an error message saying Error: Can't open display:

   I'm not sure if this is a problem of using the correct DISPLAY setting, running x11 forwarding through Google Colab or both!Can anyone help me out? Thank you!

   The relevant parts of the output of when I run !cat /etc/os-release on my Google Colab notebook.

   NAME="Ubuntu"
   VERSION="18.04.3 LTS (Bionic Beaver)"

   ID_LIKE=debian
   VERSION_ID="18.04"

   UBUNTU_CODENAME=bionic
   

   解决方案

   tl;dr

   1. Open 6000/tcp port on your router and firewall
   2. Install VcXsrv
   3. Run "XLaunch" with "Disable access control"
   4. Run "!apt-get install x11-apps && export DISPLAY=YOUR_IP_ADDRESS:0.0 && eyes" on Colab

   Check

   1. Google Colab does not keep environment variables across code cells. So you should set DISPLAY variable each them.
   2. Xming may disallow remote connection as a default setting. At least, VcXsrv do that. Try to disable access control. This is an insecure option.
   3. Router and firewall must open 6000+n/tcp port. The n is display number counting from 0. (e.g. HOSTNAME:0.0 → n=0) Open Port Check Tool - Test Port Forwarding on Your Router
