🔧 Essential CUDA Memory Fixes
1. PyTorch CUDA Out-Of-Memory (OOM) Prevention
When processing high-resolution frames (1080p / 4K) in local pipelines, set this environment flag before starting your Python runtime:
set PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True
set CUDA_MODULE_LOADING=LAZY
2. InsightFace Buffalo_L Model Cache
If your local face analyzer fails on first launch due to proxy or network timeouts, manually verify model weights are placed in:
%USERPROFILE%\.insightface\models\buffalo_l\
