I'll try to put it again

now I get this error in my Auto Scaler task
Warning! exception occurred: An error occurred (AuthFailure) when calling the RunInstances operation: AWS was not able to validate the provided access credentials Retry in 15 seconds

Hey WackyRabbit7 ,
Is this the only error you have there?
Can you verify the credentials in the task seem ok and that it didn't disappear as before?
Also, I understand that the Failed parsing task parameter ... warnings no longer appear, correct?

Just updating, I still haven't touched this.... I did not consider the time it would take me to set up the auto scaling, so I must attend other issues now, I hope to get back to this soon and make it work

Actually I removed the key pair, as you said it wasn't a must in the newer versions

I have them only in one place

Sure, we're using RunInstances , you can see the call itself https://github.com/allegroai/trains/blob/master/trains/automation/aws_auto_scaler.py#L163

I have them in two different places, once under Hyperparameters -> General

If the configurations and hyper params still appear properly in the task there's no need to rerun the wizard. just make sure you're using the updated trains repo

So what's our next move FriendlySquid61 ? O_O

I ran the wizard liek a milion times

Now I remind you that using the same credentials exactly, the auto scaler task could launch instances before

the trains ones

I'll try to debug this and updat

Actually I removed the key pair, as you said it wasn't a must in the newer versions

It isn't a must, but if you are using one, it should be in the same region

I doubled checked the credentials in the configurations, and they have full EC2 access

and when looking at the running task, I still see the credentials

Okay, I'll try that

and also in the extra_vm_bash_script variables, I ahve them under export TRAINS_API_ACCESS_KEY and export TRAINS_API_SECRET_KEY

Update - New AWS credentials solved this issue.

no need to do it again, I ahve all the settings in place, I'm sure it's not a settings thing

So just to correct myself and sum up, the credentials for AWS are only in the cloud_credentials_*

and I'm using the same credentials

Make sure you're testing it on the same computer the autoscaler is running on

Yep, the warnings no longer appear

Those are different credentials.
You should have the aws info under:
cloud_credentials_key , cloud_credentials_secret and cloud_credentials_region
And the stuff added to the extra_vm_bash_script are the trains key and secret from your profile page in the UI.
I suggest you use the wizard again to run the task, this will make sure all the data is where it should be.

Searching this error it seems it could be many things.
Either wrong credentials or a wrong region (different than the one for your key-pair).
It could also be that your computer clock is wrong (see example https://github.com/mitchellh/vagrant-aws/issues/372#issuecomment-87429450 ).
I suggest you search it online and see if it solves the issue, I think it requires some debugging on your end.

can you tell me which API call exactly are you using for spinning up? I would like to debug and try to use boto3 myself in order to spin up an instance, so I can understand where the problem is coming from
