Paperspace runs on their own machines (unlike Crestle, which runs on top of AWS)

Summary of Charges

STORAGE: 250 GB ($7/month) or 50 GB ($5/month)
USAGE: $0.40/hr (least expensive machine available)
PUBLIC IP ADDRESS: $3/month (single static IP address)

Note: There is a $15 credit code you can all use: FASTAI15

Part I: Creating a Machine

Step 1: Where to start

click on this link: https://www.paperspace.com/console/machines

Step 2: Create a new machine

select green button New Machine

Step 3: Choose region

pick a data center
Regions: there are 3 regions available
- West Coast (California)
- East Coast (New York)
- Europe
pick the one closest to you; (for me it is East Coast (NYC))

Step 4: Choose template

Select Public Templates
Select icon for fast.ai

Step 5: Choose machine

there are various machines with charges noted by the hour
Paperspace is cheaper than Crestle, with fast machines
if you choose the $0.65/hr machine, it may ask you to contact Paperspace asking why (anti-fraud step); let them know it is for fast.ai and they will get you up and running
select the $0.40/hr, the cheapest one

Step 6: Choose storage

note that you pay for storage as soon as you start the machine up
select 250 GB ($7/month) option; you can also get by with 50 GB ($5/month) option too
storage costs are pro-rated (like compute (or "usage") costs)

Step 7: Options

turn ON Public IP (cost is $3/month)
turn OFF Auto Snapshot (to save money on doing back-ups)

Step 8: Payment

add in a promo code: $15 credit code you can all use: FASTAI15
add in credit card information (required, even if you have a promo code)

Step 9: Create machine

select Create your Paperspace box
you'll see the new machine "provisioning"
it takes about a minute
you'll receive an email with subject "Your new Paperspace Linux machine is ready"
- a temporary password will be included in that email

Your temporary sign-in password for machine New Machine 1 is: *************

You can ssh into your new machine with the following command:ssh paperspace@184.105.2.222

Happy computing!

Part II: Logging into Paperspace Fastami Image Machine

select the machine in Paperspace
copy password from email
paste in terminal
- Windows: Ctrl + Shft + v
- Mac: Cmd + v
notice the prompt (fastai) paperspace@psnqh1ltz:~$

Warning: Permanently added '10.64.22.222' (ECDSA) to the list of known hosts.

🔴 Part III: Updating fastai repo contents

🔑 this step is important as having updated content and libraries can bypass errors

Step 1: go to directory

cd fastai

(fastai) paperspace@psnqh1ltz:~$ cd fastai
(fastai) paperspace@psnqh1ltz:~/fastai$ pwd
/home/paperspace/fastai
(fastai) paperspace@psnqh1ltz:~/fastai$

Step 2: update repo

git pull

from time to time, you should pull the latest fastai repo from GitHub

(fastai) paperspace@psnqh1ltz:~/fastai$ git pull
Already up-to-date.

Step 3: update Python / Anaconda libraries

conda env update

do this from time to time (every few weeks)

Part IV: Paperspace & Jupyter Notebook

Step 1: `cd` into fastai directory

make sure you are here: /home/paperspace/fastai

(fastai) paperspace@psgyqmt1m:~/fastai$ pwd
/home/paperspace/fastai
(fastai) paperspace@psgyqmt1m:~/fastai$

Step 2: Launch Jupyter Notebook

jupyter notebook

(fastai) paperspace@psgyqmt1m:~/fastai$ jupyter notebook
[I 17:16:50.591 NotebookApp] Writing notebook server cookie secret to /run/user/1000/jupyter/notebook_cookie_secret
[W 17:16:51.110 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.
[I 17:16:51.122 NotebookApp] Serving notebooks from local directory: /home/paperspace/fastai
[I 17:16:51.122 NotebookApp] 0 active kernels
[I 17:16:51.122 NotebookApp] The Jupyter Notebook is running at:
[I 17:16:51.122 NotebookApp] http://[all ip addresses on your system]:8888/?token=44cd3335e311c181531f38031095a217b01127d8152aa3fd
[I 17:16:51.122 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 17:16:51.123 NotebookApp] 
    
    Copy/paste this URL into your browser when you connect for the first time,
    to login with a token:
        http://localhost:8888/?token=44cd3335e311c181531f38031095a217b01127d8152aa3fd

Step 3: Get Notebook url

copy and paste url into your local browser (example: Chrome, Firefox, Opera, etc)
for me it is, and it WON'T WORK:
http://localhost:8888/?token=44cd3335e311c181531f38031095a217b01127d8152aa3fd
I need to replace localhost section with my IP address. This DOES WORK:
http://184.105.6.151:8888/?token=44cd3335e311c181531f38031095a217b01127d8152aa3fd

💥 Hooray, it works! 😃

Part V: Workflow

I opened the Lesson 1 notebook, made a copy with the name tmp-reshama-lesson1.ipynb

http://184.105.6.151:8888/notebooks/courses/dl1/lesson1.ipynb

🔴 Part VI: Shutting down Notebook & Machine

🔴 Remember to shut the notebook down and STOP Instance! 💰 🔴

Paperspace has an option where you can choose to automatically shut down your machine at: 1 hr, 8 hrs, 1 day, 1 week
I chose the 8 hrs option
🔑 Note that the auto shut down works only for the browser console. Paperspace will not auto shut down your server if you SSH to it.
How do I use Auto-Shutdown on my Linux machine when connecting through SSH?

Optional Steps

Skip password and updating IP address in Jupyter Notebook link

Setup: Simplifying Logging in to Paperspace

Note: the below commands are run on * YOUR LOCAL COMPUTER *

Step 1: Install `ssh-copy-id`

If you don't have it already, here's how to install it (Mac):

brew install ssh-copy-id

Step 2: Ensure public keys are available

cd into ~/.ssh directory
if you don't have an .ssh directory in your home folder, create it (mkdir ~/.ssh)
if you don't have an id_rsa.pub file in your ~/.ssh folder, create it (ssh-keygen and hit Enter 3 times)

Step 3: Copy public key to Paperspace

replace IP address in syntax below with your own, and run command

ssh-copy-id -i ~/.ssh/id_rsa.pub paperspace@184.105.2.222

Step 4: Add Paperspace info to `config` file

make sure you are in the right directory

cd ~/.ssh

if you don't have a config file, create one. This example creates file using nano editor.

nano config

add these contents to your config file (replace IP address here with your Paperspace IP address)

Host paperspace
     HostName 184.105.2.222
     IdentityFile ~/.ssh/id_rsa
     # StrictHostKeyChecking no  
     User paperspace

here's the nano command for saving file
ctrl o
Enter
here's the nano command for exiting a file
ctrl x

my example of config file

% pwd
/Users/reshamashaikh/.ssh

% cat config
Host paperspace
     HostName 184.105.2.222
     IdentityFile ~/.ssh/id_rsa
     # StrictHostKeyChecking no  
     User paperspace

ssh into Paperspace from local computer

ssh -L 8888:localhost:8888 paperspace

start Jupyter Notebook from local computer

launch Jupyter Notebook

jupyter notebook

Cool! no password required, and no need to update notebook url with IP address

this is my url link, and it works! 💥
