PreprocessorService::run | end - {"stack":"Error: PixGenie process failed with exit code 1. STDERR:

What Happened#

2026-04-20 09:35 UTC, cupixworks-pix-genie-preprocessor-instance 서비스에서 capture 45318(nswgov 테넌트)의 PixGenie 전처리 중 MobileSAMv2 모델이 165번째 이미지(전체 192장 중)에서 빈 logit tensor를 생성하여 torch.argmax()에서 IndexError가 발생했다. 이로 인해 Python 프로세스가 exit code 1로 종료되었고, Node.js agent가 capture의 pix_genie_state를 Error로 영구 설정했다.

Quick Facts#

Field Value
exception.class IndexError
exception.message argmax(): Expected reduction dim 0 to have non-zero size.
top_frame mobilesamv2.py:200
runtime Python 3.10, PyTorch (CUDA), pixgenie 0.1.28
env production, ap-southeast-2

Affected Teams#

Team / Domain Error Count Impact
sinsw / nswgov 1 capture 45318 ("3D Map [08:45 AM]") 전처리 실패, pix_genie_state가 Error로 영구 설정됨
