Accessing participant name in the compute worker

[mansur-csc]

Hello,

I was wondering if it is possible to access the participant id for the submission inside the compute worker?

I wasn't able to find a specific information regarding this. I suppose it is not accessible by default. But is there a way to work around this?

Thanks!

Hi @mansur-csc thank you for reaching out.

At the moment accessing the participant/user id in the compute worker is not possible. Do you have a use case where it is needed? Maybe describe it for us and if it is something useful for other users too we may add this option in the future.

Thank you for your quick response @ihsaan-ullah.

We have a self-hosted deployment of Codabench and we want to store each submission in a custom directory format on a bucket.

Hence, we want to be able to distinguish between the participants to place them in the bucket properly after validating their submission.

I am aware that this is not well-aligned with the design of Codabench but hoping to find a solution. It seems like it is easiest to ask the participants to include some meta information in their submission.

Thanks

Yes this should be the easiest solution to ask for meta-data with the submission. You can either ask the participants to include something in the submission itself or you can add fact sheet to your competition. If you mark the factsheet required, users will be forced to provide in a form field what you ask for. We usually use this to ask for description of the submission.

You can find fact sheet in the edit mode of your competition.

oh I see. So, if I enable the factsheet and ask them to input their username in the text field, that information will be accessible in the compute worker, is that right?

Thanks

This information will not be available in the compute worker. Only anything inside the submission zip will be accessible.

Sorry for the confusion.

[mansur-csc]

Okay, thank you for the clarification.

Hi @mansur-csc

Thanks to our team member @ObadaS , it looks like you can actually find the user_id inside the compute worker. Please check this function that passes data to the compute worker. You can find the user_id there. If you check the logs of your compute worker you will find the user id in the logs too.

I hope this will solve your problem.

[mansur-csc]

Thank you @ihsaan-ullah and @ObadaS. I will check this function and update this discussion later.

[mansur-csc]

I can confirm that this actually works
