Google colab is a good option to experiment and try heavy computational tasks on a high end computer for free. Notebook interface provided by google is perfect python programs.
I have made a script to connect to colab instance with just few comands.
What you need ?
-
ngrok Account
-
ssh public key
Go to https://ngrok.com and create an account and copy the authtoken only
./ngrok authtoken ZT64bWYnXsdTAdfdassJej4FNFT_2auAQqKqZHn2Sh4g2sfAD
we need only last argument of command from above.
for second option : run ssh-keygen and just press enter 3–4 times if it asks for anything
and then copy the public key
run cat .ssh/id_rsa.pub
reference is here
now open google colab, connect to desired runtime type and execute following commands in notebook cell:
! wget https://gist.githubusercontent.com/archie9211/ae3c8411da88ae8b2a05b0ee1a4fd412/raw/ee1a6e78fc498ad6d4830cd2eb6033839235ea8a/colab-ssh-jupyter.sh
!bash colab-ssh-jupyter.sh
Enter the authtoken and ssh public key when prompt asks respectively.
it will print the ssh command to connect to colab instance. e.g
ssh [email protected] -p 16826 # it will be different for your case
Open terminal in your local pc and run the command you get on colab.
you will get a bash shell logged in to colab instance. for jupyterlab, first install following on the terminal :
pip3 install jupyterlab && apt install tmux
now run tmux and run following command in it: (chose port of your choice {I prefer 5 digit random number})
jupyter lab --ip 0.0.0.0 --port 56784
now press ctrl + b and then “ to split split window and then run follow in new window: (use the same port you used for jupyter lab)
ssh -R 80:localhost:56784 [email protected]
You should get a URL after this on terminal open this in browser and you should get your jupyter lab on browser connected to google colab instance.
To minimize tmux on terminal, press ctrl+b and then d.
