Documents all pitfalls encountered during setup:
- CUDA arch mismatch (sm_120 vs sm_89) — source rebuild needed
- utils3d empty pip package → GitHub fork required
- transformers v5 DINOv3 API change → sed patch
- xformers version pinning (0.0.33.post2 for torch 2.9.1)
- Missing Eigen headers for cumesh build
- visualbruno forks needed for o_voxel and cumesh (newer functions)
- /tmp disk space issues during pip builds
Includes:
- SETUP.md: Full step-by-step guide
- requirements.txt: Pinned dependency versions
- fix_transformers_v5.sh: Apply DINOv3 layer patch
- build_cuda_extensions.sh: One-shot source build of all CUDA extensions
