AWS fastami GPU Image Setup Part 1 v2
Notes from Lesson 2 live on 06-Nov-2017

Part I - Setting up AMI

AMI (Amazon Machine Image): a template for how your computer is created

Step 0: Getting Started

Log into AWS Console:
Select Service: EC2
Launch Instance

Step 1: Choose an Amazon Machine Image (AMI)

  • Search Community AMIs [left menu]
  • Search: fastai
  • Select this image (for region N. Virginia): fastai-part1v2-p2 - ami-c6ac1cbc

NOTE: this AMI is available in a number of regions. Check your local region first. If it's not available, check next closest region.

  • Oregon: ami-8c4288f4
  • Sydney: ami-39ec055b
  • Mumbai: ami-c53975aa
  • N. Virginia: ami-c6ac1cbc
  • Ireland: ami-b93c9ec0

Step 2: Choose an Instance Type

(Note: it is the kind of computer we want to use.)

  • Filter by: GPU Compute
  • Select: p2.xlarge (this is the cheapeast, reasonably effective for deep learning type of instance available)
  • Select: Review and Launch at bottom

Step 2b: Select keypair

Note: you have already created a keypair in the past. Use one of those. For more specific instructions, see Create a Keypair.

And, voila! We have just created a new computer on AWS that we can log into 💥

Part II - Logging into our AWS Computer

Syntax for logging in and setting up tunnel for Jupyter Notebook

Note 1: Ensure you are in your .ssh directory on your local computer. (where your keypair file is located)
Note 2: You will put your Public IP address where mine is.
Note 3: This part -L8888:localhost:8888 connects Jupyter Notebook from AWS to your computer.

my current path


my syntax for logging in

ssh -i aws_fastai_gpu.pem ubuntu@ -L8888:localhost:8888

my example

▶ ssh -i aws_fastai_gpu.pem ubuntu@ -L8888:localhost:8888

Working on our AWS Computer

List what files are loaded on the AWS computer:

my example

(fastai) ubuntu@ip-172-31-10-243:~$ ls
data  fastai  src
(fastai) ubuntu@ip-172-31-10-243:~$

cd into the fastai repo

cd fastai

my example

(fastai) ubuntu@ip-172-31-10-243:~$ cd fastai
(fastai) ubuntu@ip-172-31-10-243:~/fastai$ ls -alt

Note 1: The fastai repo is available in your home directory, in the fastai folder.
Note 2: The dogscats dataset is already there for you, and the data folder is linked to ~/data.

Update the conda libraries (do this once a month, or if you run into errors)
conda env update
conda update --all


  • check which version of python is running
    • python --version
  • check which python path is being used
    • which python
  • see what packages are installed
    • pip list --format=legacy

my example

(fastai) ubuntu@ip-172-31-10-243:~/fastai$ python --version
Python 3.6.3 :: Anaconda, Inc.
(fastai) ubuntu@ip-172-31-10-243:~/fastai$ which python
(fastai) ubuntu@ip-172-31-10-243:~/fastai$ 

Part III - Jupyter Notebook

Create a Jupyter config

jupyter notebook --generate-config

Open the config file generated and add the following line

c.NotebookApp.ip = '*'

Launch Jupyter Notebook
jupyter notebook

my example

(fastai) ubuntu@ip-172-31-10-243:~/fastai$ jupyter notebook

Going to "MY URL" for Jupyter Notebook


Note: you will want to edit the above url with YOUR TOKEN.

This notebook is running on AWS GPU machine.
The p2 instance costs $0.90 per hour 💰
The p3 instance costs $3.00 per hour 💰 💰 💰
Storage: ~ $8 per month for storing data files (80GB GP2 SSD @ $0.10 GB/month)

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


I opened the Lesson 1 notebook, made a copy with the name tmp-reshama-lesson1.ipynb and was able to run all the code! 💥

Note on Tmux

On the fastai AWS AMI, tmux mouse mode is enabled, so hold down shift while selecting to copy to your local clipboard.
