Hello Channel, I Am Struggling A Lot On An Issue Linked To

Hello channel,

I am struggling a lot on an issue linked to ClearMl agent and AWS Autoscaler .
This issue is very problematic and urgent, please help me out! We need the autoscaler to work to be able to pull and execute our tasks correctly.

Context:
I want to install a poetry environment from a poetry.lock file located at the root of my repository.
I have a bash script running allowing to install poetry and install python 3.9.16 using Pyenv (needed by my poetry env).
The installation goes on, my repository is cloned, poetry is detected and then poetry installation fails directly without any logs (even when using the verbose mode).

Here is the clearml.conf of my AWS autoscaler config and the logs of one of the latest runs (you can find the bash script inside it) + snippet of the error :

Poetry Enabled: Ignoring requested python packages, using repository poetry lock file!
Creating virtualenv alfred in /root/.clearml/venvs-builds/3.9/task_repository/alfred.git/.venv
Using virtualenv: /root/.clearml/venvs-builds/3.9/task_repository/alfred.git/.venv
Installing dependencies from lock file
Finding the necessary packages for the current system
Package operations: 351 installs, 1 update, 1 removal, 22 skipped
failed installing poetry requirements: Command '['poetry', 'install', '-n', '-v']' returned non-zero exit status 1.
Ignoring pip: markers 'python_version >= "3.10"' don't match your environment 
agent {
    vcs_cache.enabled: false

    package_manager: {
          type: poetry,
          poetry_version: "1.4.2",
          poetry_install_extra_args: ["-v"],
     }  
}

sdk {
    development {
         store_code_diff_from_remote: false,
    }

}

Issue and what has been done:

  • I tested all clearml.co nf parameters without success
  • I created an AWS instance, ssh-ed into it and try the installation of poetry and it worked...
  • Last but not least which leads to my full confusion : I setted up SSH access to the AWS autoscaler instances, SSHed to it during runtime, went into the created docker container, waited until the git clone command made effect and poetry installation failed to be able to try myself the poetry install -n -v command. Again, It worked... I am extremely confused because it works on the instance itself created by the autoscaler, but it does not work when running on ClearML. What am I missing??
    Thank you a lot for your time,

Because I was ssh-ing to it before the fail. When poetry fails, it installs everything using PIP

Yes same error

How do you explain that it works when I ssh-ed into the same AWS container instance from the autoscaler?

  
  
Posted one year ago

You can theoretically do that in the docker init bash script that will be executed before the task is cloned and run

  
  
Posted one year ago

How is it still up is the task failed?

  
  
Posted one year ago

So the same?

@<1523701087100473344:profile|SuccessfulKoala55> Do you think it is possible to ask to run docker mode in the aws autoscaler, and add the cloning and installation inside the init bash script of the task?

  
  
Posted one year ago

When the task finally failed, I was kicked of from the container

I am currently trying with a new dummy repo and I iterate over the dependencies of the pyproject.toml.

@<1556812486840160256:profile|SuccessfulRaven86> , to make things easier to debug, can you try running the agent locally?

  
  
Posted one year ago

@<1556812486840160256:profile|SuccessfulRaven86> , did you install poetry inside the EC2 instance or inside the docker? Basically, where do you put the poetry installation bash script - in the 'init script' section of the autoscaler or on the task's 'setup shell script' in execution tab (This is basically the script that runs inside the docker)

It sounds like you're installing poetry on the ec2 instance itself but the experiment runs inside a docker container

@<1523701070390366208:profile|CostlyOstrich36> poetry is installed as part of the bash script of the task.

The init script of the AWS autoscaler only contains three export variables I set.

@<1556812486840160256:profile|SuccessfulRaven86> can you try with -vvv instead of -v ?

I tried too. I do not have more logs inside the ClearML agent 😞

  
  
Posted one year ago

I also did that in the following way:

  • I put a sleep inside the bash script
  • I ssh-ed to the fresh container and did all commands myself (cloning, installation) and again it worked...
  
  
Posted one year ago

Yes indeed, but what about the possibility to do the clone/poetry installation ourself in the init bash script of the task?

  
  
Posted one year ago

the autoscaler always uses docker mode

@<1523701070390366208:profile|CostlyOstrich36> @<1523701087100473344:profile|SuccessfulKoala55> I tried with dummy repo. Using Python and stripe packages ONLY in the pyproject.toml

Here is my result (still failing) :

Poetry Enabled: Ignoring requested python packages, using repository poetry lock file!
Creating virtualenv debug in /root/.clearml/venvs-builds/3.9/task_repository/clearmldebug.git/.venv

This is really extremely hard to debug. I am thinking to create another repo and iterate on the packages to hopefully find the problem, but it will take ages.

  
  
Posted one year ago

Yes, the problem is it's still really hidden (the error, I mean)

How to make sure that the python version is correct?

  
  
Posted one year ago

I see it's running inside 3.9, so I assume it's correct

  
  
Posted one year ago

where did you specify it?

  
  
Posted one year ago

I am literrally trying with 1 package and python and it fails. I tried with python 3.8 3.9 and 3.9.16. and it always fail --> not linked to python version. What is the problem then? I am wondering if there is not an intrinsic bug

  
  
Posted one year ago

The autoscaler just runs it on an AWS instance, inside a docker container - there's no difference from running it yourself inside a docker container - did you try running it inside a docker container as well?

  
  
Posted one year ago

I literrally connected to it at runtime, and ran poetry install -n and it worked

  
  
Posted one year ago

Using a pyenv virtual env then exporting LOCALPYTHON env var

  
  
Posted one year ago

Yes should be correct. Inside the bash script of the task.

  
  
Posted one year ago

Is it a bug inside the AWS autoscaler??

  
  
Posted one year ago

I think you should try to manually start such a docker container and try to see what fails in the process. Attaching to an existing one has too many differences already
