是否可以将vscode(在本地计算机上)与Google Colab(免费服务)运行时连接? [英] Is it possible to connect vscode (on a local machine) with Google Colab (the free service) runtime?

问题描述

我知道在GCP上，我们可以设置一个vscode服务器并连接到该服务器.但是我想知道的是，是否可以连接到Google Colab上的运行时实例(免费实例，即:

I know on GCP, we can set up a vscode server and connect to that. But what I'm after here, is to know whether it is possible to connect to the runtime instance on Google Colab (the free one ie: https://colab.research.google.com) from a locally run vscode. If I'm not mistaken, we can connect to any remote Jupyter kernel in vscode instead of creating a new instance locally and connecting to it.

所以我想知道是否有可能先创建一个Python 3笔记本，然后在您的本地计算机上启动vscode，连接到Colab运行时并在vscode中进行编码?

So I want to know if it is possible to first create a Python 3 notebook and then from your local machine, fire up vscode, connect to the Colab runtime and code inside vscode ?

这里没有本地内容，所有文件，笔记本，所有内容都驻留在Google Colab上，而只是使用vscode而不是Google自己的编辑器进行编码和执行代码(调试等).

There is nothing local here, all files, notebooks, everything resides on Google Colab, it's just the coding and executing the code (debugging, etc) using vscode instead of Google's own editor.

感谢您的回答，我可以成功连接到Google Colab.但是，当我退出ssh并尝试再次登录时，我遇到了这个问题:

Thanks to the answer, I could successfully connect to Google Colab. However, when I exited the ssh and tried to log in again I faced this:

我重新启动了Google Colab运行时，甚至更改了ngrok令牌并再次尝试，不走运！

I restarted the Google Colab runtime, I even changed the ngrok token and tried again, no luck!

推荐答案

是的，这很有可能.今天才处理.

Yes, it is very possible. Just managed it today.

您需要做的是与google collab建立ssh连接. 将其写在google collab jupyter笔记本上:

What you need to do is create an ssh connection with the google collab. Write this on a google collab jupyter Notebook:

import random, string
password = ''.join(random.choice(string.ascii_letters + string.digits) for i in range(20))

#Download ngrok
! wget -q -c -nc https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip
! unzip -qq -n ngrok-stable-linux-amd64.zip
#Setup sshd
! apt-get install -qq -o=Dpkg::Use-Pty=0 openssh-server pwgen > /dev/null
#Set root password
! echo root:$password | chpasswd
! mkdir -p /var/run/sshd
! echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
! echo "PasswordAuthentication yes" >> /etc/ssh/sshd_config
! echo "LD_LIBRARY_PATH=/usr/lib64-nvidia" >> /root/.bashrc
! echo "export LD_LIBRARY_PATH" >> /root/.bashrc

#Run sshd
get_ipython().system_raw('/usr/sbin/sshd -D &')

#Ask token
print("Copy authtoken from https://dashboard.ngrok.com/auth")
import getpass
authtoken = getpass.getpass()

#Create tunnel
get_ipython().system_raw('./ngrok authtoken $authtoken && ./ngrok tcp 22 &')
#Print root password
print("Root password: {}".format(password))
#Get public address
! curl -s http://localhost:4040/api/tunnels | python3 -c \
    "import sys, json; print(json.load(sys.stdin)['tunnels'][0]['public_url'])"

检查您的ngrok状态以获取您的端口号(通过网站)

Check your ngrok status to get your portnum(via the website)

之后，您可以通过ssh连接到collab:

After that you can connect to collab via ssh:

这是终端命令:

$ ssh <user>@0.tcp.ngrok.io -p <portNum>

(它将要求您提供上述代码段生成的密码) 您应该现在就可以连接.

(it will ask you for the password generated by the above snipet) You should be able to connect now.

但是，如果您想使用vscode， 通过远程SSH扩展与ssh重复连接

But if you want to use vscode, repeat the connection with ssh via the Remote SSH extension
