Root Cause

DataLoader pin_memory fails without CUDA.

generic

Workarounds

  1. 92% success Set pin_memory=True only when torch.cuda.is_available()
  2. 88% success Use pin_memory=False for CPU-only training

Dead Ends

Common approaches that don't work:

  1. Ignore error and continue without pinning 65% fail

    Slower data transfer when GPU available

  2. Force CUDA initialization 88% fail

    Fails without GPU hardware
