fix(L4T13 backends): switch vllm/sglang/vllm-omni to PyPI aarch64+cu130 wheels (#9950)
* fix(vllm): switch L4T13 backend to PyPI aarch64+cu130 wheels The L4T13 vllm backend pulled torch / torchvision / torchaudio / vllm from pypi.jetson-ai-lab.io's sbsa/cu130 mirror via [tool.uv.sources] with no version pins. That mirror started shipping torch 2.11.0 next to a vllm-0.20.0+cu130 wheel that was still compiled against torch 2.10's c10 ABI, so uv landed on the mismatched pair and vllm crashed at import: ImportError: vllm/_C.abi3.so: undefined symbol: _ZN3c1013MessageLoggerC1EPKciib (c10::MessageLogger's constructor signature changed between torch 2.10 and 2.11; the vllm wheel referenced the 2.10 form, the installed libc10.so exported only the 2.11 form.) Since torch 2.11 (April 2026) PyPI publishes its own aarch64 + cu130 manylinux wheels, and vllm 0.20.0 ships an aarch64 wheel whose Requires- Dist locks torch==2.11.0 / torchvision==0.26.0 / torchaudio==2.11.0. That makes uv's resolver produce an ABI-consistent set automatically, so the mirror and the [tool.uv.sources] pinning are no longer needed. flash-attn is dropped from the dep list: PyPI has no aarch64 wheel, but vLLM 0.20+ already bundles its own vllm_flash_attn (fa2 + fa3) inside the main wheel, so the Dao-AILab package isn't required at runtime.

The previous commit dropped [tool.uv. sources] (PyPI now serves the aarch64 + cu130 wheels directly), so the file no longer carries any logic the requirements-*.txt path can't. Replace with the same two-file pattern every other build profile uses: - requirements-l4t13.txt (accelerate / torch / transformers / bitsandbytes - matches cublas13's split) - requirements-l4t13-after.txt (vllm; runs after the base resolve so the cu130 torch wheel lands first) install.sh's whole l4t13 elif branch goes away; libbackend.sh's installRequirements already handles the requirements-install.txt build- deps pass, the C_INCLUDE_PATH export for PORTABLE_PYTHON, and the runProtogen call, so falling through to the standard else: branch produces identical install behavior with less surface area. No functional change at install time - same wheels, same order.

The historical comment said the [all] extra was unsafe on aarch64 because of decord, but sglang 0.5.x now uses `decord2` on aarch64/arm/armv7l (which ships cp312 aarch64 wheels), so we can match cublas13's sglang[all]>=0.5.11 pin and stop being capped at the 0.5.1.post2 the L4T mirror shipped. That unblocks Gemma 4 / MTP recipes on Jetson Thor. - New requirements-l4t13.txt mirrors the cublas13 split (accelerate / torch / torchvision / torchaudio / transformers), requirements-l4t13- after.txt carries sglang[all]>=0.5.11. - install.sh's l4t13 elif branch goes away; falls through to the standard installRequirements path. vllm-omni --------- - requirements-l4t13.txt drops --extra-index-url to jetson-ai-lab and drops flash-attn (PyPI has no aarch64 wheel, vLLM 0.20+ bundles its own vllm_flash_attn fa2 + fa3 internally). - install.sh's l4t13 vllm-install branch collapses into the cublas13 branch since both now just run `pip install vllm --torch-backend=auto` against PyPI. - --index-strategy=unsafe-best-match is dropped from the top-level l4t13 guard; without the L4T mirror in the picture it had no purpose. The from-source vllm-omni install on top still keeps its existing `sed -i '/^fa3-fwd[[:space:]]*==/d' requirements/cuda.txt` workaround - fa3-fwd has no aarch64 wheel and no sdist, unrelated to flash-attn.

Its sdist depends on scikit_build_core without declaring it in build-system. requires, so under --no-build-isolation uv can't build it from source: × Failed to build `xatlas==0.0.11` ├─▶ The build backend returned an error ╰─▶ Call to `scikit_build_core.build.build_wheel` failed (exit status: 1) ModuleNotFoundError: No module named 'scikit_build_core' help: `xatlas` (v0.0.11) was included because `sglang[all]` (v0.5.12) depends on `xatlas` Upstream sglang explicitly gates st_attn and vsa on `platform_machine != aarch64` inside the same [diffusion] extra but forgot xatlas - same class of bug that bit the old decord pin. Use plain `sglang>=0.5.11` on l4t13. backend.py imports only base sglang.srt symbols (Engine, ServerArgs, FunctionCallParser, ReasoningParser); the [all] extras are optional accelerators not required at import time. cublas13 (x86_64) keeps [all] because xatlas has x86_64 wheels there.

fix(ci): unbreak rerankers (torch bump) and vllm-omni on aarch64 (#9688)
Two unrelated CI breakages bundled together since both are one-liners: - rerankers: bump torch 2.4.1 -> 2.7.1 on cpu/cublas12. The unpinned transformers resolves to 5.x, whose moe.py registers a custom_op with string-typed `'torch.Tensor'` annotations that torch 2.4.1's infer_schema rejects, blocking the gRPC server from starting and failing all 5 backend tests with "Connection refused" on :50051. Matches the version used by the transformers backend. - vllm-omni: strip fa3-fwd from the upstream requirements/cuda.txt before resolving on aarch64. fa3-fwd 0.0.3 ships only an x86_64 wheel and has no sdist, making the cuda profile unsatisfiable on Jetson/SBSA. fa3-fwd is a soft runtime dep — vllm-omni's attention backends fall back to FA2 then SDPA when it's missing.

feat(backends): add CUDA 13 + L4T arm64 CUDA 13 variants for vllm/vllm-omni/sglang (#9553)
* feat(backends): add CUDA 13 + L4T arm64 CUDA 13 variants for vllm/vllm-omni/sglang
Adds new build profiles mirroring the diffusers/ace-step pattern so vLLM
serving (and SGLang on arm64) can be deployed on CUDA 13 hosts and
JetPack 7 boards:
- vllm: cublas13 (PyPI cu130 channel) + l4t13 (jetson-ai-lab SBSA cu130
prebuilt vllm + flash-attn).
- vllm-omni: cublas13 + l4t13. Floats vllm version on cu13 since vllm
0.19+ ships cu130 wheels by default and vllm-omni tracks vllm master;
cu12 path keeps the 0.14.0 pin to avoid disturbing existing images.
- sglang: l4t13 arm64 only — uses the prebuilt sglang wheel from the
jetson-ai-lab SBSA cu130 index, so no source build is needed.
Cublas13 sglang on x86_64 is intentionally deferred.
CI matrix gains five new images (-gpu-nvidia-cuda-13-vllm{,-omni},
-nvidia-l4t-cuda-13-arm64-{vllm,vllm-omni,sglang}); backend/index.yaml
gains the matching capability keys (nvidia-cuda-13, nvidia-l4t-cuda-13)
and latest/development merge entries.

* fix(backends): use unsafe-best-match index strategy on l4t13 builds
The jetson-ai-lab SBSA cu130 index lists transitive deps (decord, etc.)
at limited versions / older Python ABIs. uv defaults to the first index
that contains a package and refuses to fall through to PyPI, so sglang
l4t13 build fails resolving decord. Mirror the existing cpu sglang
profile by setting --index-strategy=unsafe-best-match on l4t13 across
the three backends, and apply it to the explicit vllm install line in
vllm-omni's install.sh (which doesn't honor EXTRA_PIP_INSTALL_FLAGS).
Assisted-by: Claude:claude-opus-4-7 [Read] [Edit] [Bash]
* fix(sglang): drop [all] extras on l4t13, floor version at 0.5.0
The [all] extra brings in outlines→decord, and decord has no aarch64
cp312 wheel on PyPI nor the jetson-ai-lab index (only legacy cp35-cp37
tags). With unsafe-best-match enabled, uv backtracked through sglang
versions trying to satisfy decord and silently landed on
sglang==0.1.16, an ancient version with an entirely different dep
tree (cloudpickle/outlines 0.0.44, etc.).
Drop [all] so decord is no longer required, and floor sglang at 0.5.0
to prevent any future resolver misfire from degrading the version
again.
