[Bug Report] Model Evaluation Fails Due to Preprocessing Resize

Environment

  • Plan: Basic Plan

  • Workflow: Using preprocessing (resize to 2048×2048), then training

Issue Description
I reported this bug through the Report a Bug option in the Roboflow UI yesterday, but I cannot see the ticket status or receive any email/notification updates.
The actual issue I encountered is: after uploading tiled images (2048×2048) and applying preprocessing resize, even the model training was able to complete, HOWEVER the model evaluation fails with the following error:

image
image1446×395 29.2 KB

There is no detailed log about the cause, which makes it difficult to debug.

Steps to Reproduce

  1. Upload dataset with tiles (2048×2048 each).

  2. In preprocessing, select “Resize to 2048×2048.”

  3. Train a model.

  4. During evaluation, the error occurs (no evaluation results).

Expected Behavior
The evaluation should complete successfully, or at least provide a clear error message/log.

Notes

  • The dataset was already tiled before upload.

  • I suspect Roboflow may be by default resizing to 640×640, which could conflict with my preprocessing setup.

  • If I select “Resize to 1024×1024”, everything just fine.

Could you please check this issue and confirm whether it is a known resource limitation by roboflow or a bug?
