Jason Kneen	3e184d343e	Improve Mac/MPS compatibility and device handling ... Added dev/runmac_overnight.sh for optimized Mac training. Updated device-specific logic throughout dataloader, GPT, Muon optimizer, and training scripts to avoid CUDA-only features on MPS/CPU (e.g., torch.compile, pin_memory, non_blocking, bfloat16). Relaxed torch version constraints in pyproject.toml and removed Linux/CUDA-specific PyTorch config for better macOS support.	2025-10-22 01:55:38 +01:00

karpathy	2e9669e03a	upgrading all other files to be able to use cpu/mps as well as cuda. various minor other changes ,e.g. changing max_iterations to num_iterations in sft script for consistency in naming	2025-10-20 10:15:17 -07:00
