Dear VLM3D Challenge Organizers, I am writing to you as a participant in the Task2:Multi-Abnormality Classification under the username hyena. I am encountering a persistent "Import Failed" error when trying to submit my algorithm model.

Initially, my submissions were failing with the error message "algorithm model with this sha256 already exists." This was surprising, as my model is a custom CNN architecture that I have personally trained on the CT-RATE dataset. Given its unique training and structure, a hash collision with another participant's submission seems highly unlikely.

Nevertheless, to rule out any issues on my end, I have taken rigorous steps to ensure every subsequent submission is unique. I have confirmed using sha256sum that each new .tar.gz archive has a different hash value. These unique files were generated by altering the model's architecture and weights between submissions.

Despite these efforts and the confirmed uniqueness of each submitted file, all of my submissions continue to result in an "Import Failed" status.

Could you please advise if there is another reason for the failure, or if there are any specific requirements for the model or archive structure that I may have missed?

Thank you for your time and assistance. I look forward to your reply.

Best regards, hyena
