Decide when to use OpenCV’s CPU or GPU resize: compare CPU, CUDA, and OpenCL options, weigh speed vs. portability, and see a ready‑to‑run C++ example with validation checks.
Goal: assess whether the forkserver start method can be employed with PyTorch DataLoader workers to avoid per‑worker CUDA context re‑initialization while maintaining safe GPU usage in distributed training. Constraints: the official documentation warns that fork‑ing a process holding CUDA resources is unsafe, and there is no stable API for forkserver in PyTor
