Hi everyone, I’d like to check if anyone else is facing the same issue.
I have been using Realtek’s **online model conversion service** (to convert YOLOv7-tiny Pytorch models into `.nb` format). Normally, it takes only about 2–3 minutes to complete.
Last week the service was still working fine, but today it suddenly stopped working. After uploading the files, the system no longer produces the `.nb` model — it just gets stuck or shows no response. I tried multiple times with different models and settings, but the result is always the same.
