Comment-only. Pins the invariant that deepspeed (kept for multi-GPU training) needs nvcc, which only the gpu-devel base ships — so the image must build on saturnbase-python-gpu-devel-12.9 (set in release-images data_science.py, PR #485). Prevents a future revert to the runtime base from silently re-breaking every axolotl job at Trainer init. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Comment-only clarification (no dependency change — the env already has
[deepspeed]).Pins the invariant discovered while getting axolotl training to work end-to-end: deepspeed requires nvcc, which only the
-develbase ships. accelerate imports deepspeed unconditionally when installed, so on a runtime base every axolotl job crashes at Trainer init (FileNotFoundError: .../nvcc) — even single-GPU jobs.The actual fix is in release-images#485 (switch this image's base to
saturnbase-python-gpu-devel-12.9). This comment prevents a future revert to the runtime base from silently re-breaking training.Supersedes #479 (which dropped deepspeed — we keep it for multi-GPU instead).
