Setup problems: AWS


#921

Hi all,

with a lot of difficulties I got to this point: when runing “bash setup_p2.sh” I get

"Only us-west-2 (Oregon), eu-west-1 (Ireland), and us-east-1 (Virginia) are currently supported "

But if I run “aws configure get region” I get “eu-west-1”. I don’t know what’s the problem.

I’m using Cygwin on Window 10 64.

Thanks in advance. Looking forward to starting the course


(Gaurav Rele) #922

in your “aws configure” command, try to manually add the region as us-west-2

if that doesnt fix it then go to ~/.aws/config using an editor like vi “vi ~/.aws/config/” to check what your region is.


(Matthew Hutson) #923

Hi,

I ran the setup script (modified for t2_medium), which created a t2_medium instance and a 128 GB volume. I detached the 128 GB volume and created and attached a 30 GB volume (with the device name “/dev/sda1”).

But when I try to start the instance, it immediately stops and I get this message: “Client.InstanceInitiatedShutdown: Instance initiated shutdown”. Do you know why that happens?

(Somewhere else I read that this problem may occur when there’s no OS on the volume, but I don’t know how to tell if that’s the case here.)

Thanks.


(Gaurav Rele) #924

I think your answer lies in doing something similar to what this post tells you

https://www.codesd.com/item/why-is-the-ec2-instance-not-started-successfully-after-resizing-the-root-ebs-volume.html


(Matthew Hutson) #925

Thanks. Can I just create a new instance with a 30 GB volume? I’ve done a lot of Googling on how to specify the volume size when creating an instance, without any luck.


(Gaurav Rele) #926

yeah i dont know any way to do that either. But after you create your instance you can use a command like this

aws ec2-modify-volume-attribute --volume --size -

to reduce the size and see if that works?


#927

Hi Nell.

Thanks for your answer. I have tried both, but without success.

“vi ~/.aws/config” gave me

[default]
output = text
region = us-west-2

so I understand the region is properly setup.
I also have the limit increase approved from AWS for this region.
Isn’t it necesary to lounch the instance from AWS previously?

Thanks.


(Gaurav Rele) #928

Hi Victor,

what do you get when you do ‘aws configure get region’ ? If you get us-west-2 then there is something else wrong. If you still get eu-west-1 then try to run aws configure and add your secret key and access key there.


#929

I can see on the AWS console, the EC2 service limit in the EU west (Irland) for p2.xlarge instances is 1, as I requested and they approved. I have added my access key and my secret key to eu-west-1 region in Cygwin. And I get eu-west-1 with “aws configure get region” … But “bash setup_p2.sh” doen’t work yet. It still says “Only us-west-2 (Oregon), eu-west-1 (Ireland), and us-east-1 (Virginia) are currently supported”.

Any ideas.

Thanks


(Gaurav Rele) #930

Hi Victor,

You need to create your ec2 instance in a different region since the fast ai AMI isnt there in that region. AMI’s are region specfic so you need to create your instance in a region that is supported which is either us-west-2, eu-west-1 or us-east-1. As far as what you need to change, you need to only change your region to one of those 3 to make it work.


#931

Hi Nell,

I have the EC2 instance limit of 1 for the us-west-2 region. I have deleted the user in the AWS console and created again. I have configured the AWS with new keys and us-west-2 region, but, unfortunately, I get the same results when runing bash setup_p2.sh.

Any other idea, please?

Thanks

Requested my AWS service increase (and had it approved) and have everything else running up to this step-- but when I run
bash setup_p2.sh
I get:
An error occurred (OptInRequired) when calling the CreateVpc operation: You are not subscribed to this service. Please go to http://aws.amazon.com to subscribe.

and then a few hundred more lines of error finished with blank values for the results.


(Will) #933

So I’ve fixed my above problem, and have a new error-- the console outputs:
rtbassoc-b59dface
True
setup_p2.sh: line 13: /Users/willmanidis/.ssh/aws-key.pem: Permission denied

An error occurred (InvalidKeyPair.NotFound) when calling the RunInstances operation: The key pair 'aws-key' does not exist
Waiting for instance start...

(Cynosure) #934

possibilities:

  1. The key pair on AWS doesnt exist (try recreating)?
  2. You dont have assigned the permissions, in AWS console go to your instance in click on security groups, “fast ai security group”, under “Inbound” see if you have authorized your local machine. to make it sure click Edit and then Choose MyIP or Anywhere in the source and try again.
  3. If you did 1 maybe the keys are not associated with your instance anymore ?

if it doesnt work, it might save you time to start over again and create AWS instance from scratch (but delete all the key pairs, elastic ip etc before).

Dear Jeremy, Thank you for posting videos on deep learning, which are really useful. I have some issues in lesson 0 that is setting up AWS server. Everything went smoothly that is starting from configuring AWS to until the command $bash setup_P2.sh. When I ran this command in cygwin, it always says that maximum no. of attempts exceeded. I paste the message below. I would really appreciate if you could help me solving this error.
$ bash setup_p2.sh

(Cynosure) #936

IIRC there is a limit on VPCs (can found in AWS console)

Capture
Try deleting all the resources that you dont need and use (in AWS console) to see if it helps.

or delete everything and start over again.


(Deepak) #937

Hi, Thanks for help. I did exactly the same.
Below you can see that I completely deleted VPC files.

After that, I followed same instructions and still I get same error. Below I post. Would appreciate your help

(Cynosure) #938

It seems you could configure aws but there are several errors.

  1. You haven’t installed pip
  2. “home/klnde/.ssh/aws-key.pem: No such file or directory” It seems your user doesnt has permissions. try giving your user all permissions for this folder/file.

Did you deleted everything from your AWS account and started over again? By everything i mean all of the links that appear in the console;

PS : You are using 128 GB instance which is expensive. search on forum there is possible reduce the size of instance to reduce the costs.


(Deepak) #939

Hi,
Yes, I deleted everything and tried. You can see below the screen shot. Nothing appears.

Coming to the command pip, it did not work and hence I used pip2. Actually this information I got from the form. Anyway, I will uninstall Python and cygwin and start from the scratch. Hope it works. I am new to this
Thanks
Deepak


(Cynosure) #940

Sorry, i didnt mean reinstalling python and Cygwinn. I mean only AWS stuff. Just check your Python version. i am working with 2.7.

if Python version is correct, i dont think there is any problem with your local machine. its only the connection and setup settings with AWS that needs to be adjusted.

Did you tried giving permission to your usr (with which you login) to that key folder ?

PS: I worked with Oregon region and it worked fine. Maybe you can try changing the region?
