8d6fdf22d3 fix(backends): derive the protoc generator from the protobuf runtime, regenerate stubs after late installs (#11057)
* fix(backends): choose the protoc generator from the protobuf runtime, and regenerate stubs after late installs

The vLLM backends still crash on startup with

  VersionError: Detected incompatible Protobuf Gencode/Runtime versions when
  loading backend.proto: gencode 7.35.0 runtime 6.33.6

despite #10735 and #10944. Three separate defects kept it alive.

1. runProtogen picked the generator from the installed *grpcio* version.
   grpcio-tools' version tracks grpcio, but the gencode its bundled protoc
   emits tracks *protobuf*, and the two move independently: grpcio-tools
   1.82.1 (the version #10735 pins to, matching grpcio 1.82.1) requires
   protobuf>=7.35.1 and stamps gencode 7.35.0. Pinning to grpcio could
   therefore never constrain the gencode. Constrain the install to the
   protobuf already in the venv instead and let the resolver pick the newest
   compatible grpcio-tools. That both selects a generator the runtime accepts
   and stops protogen from moving the runtime under the backend's other deps.
   This is self-correcting, so the hardcoded GRPCIO_TOOLS_VERSION=1.78.0
   escape hatch from #10944 is no longer needed and is removed.

2. The stubs were generated too early. Most branches of vllm/install.sh (and
   vllm-omni) install vllm *after* installRequirements, and vllm re-resolves
   the protobuf runtime as it lands. Stubs generated against the pre-vllm
   runtime can end up newer than the runtime that finally ships, which is the
   ROCm failure exactly. Regenerate once the dependency set is final.

3. rm -f of the .py sources left __pycache__ behind. CPython validates a .pyc
   against source mtime and size, both of which can be unchanged across a
   regeneration (the gencode triple is the same width whether it reads 7.35.0
   or 6.33.5), so a stale backend_pb2.pyc could shadow the stub just written.

Also fail the build when the generated stub cannot be imported, so a
gencode/runtime mismatch surfaces at image build time instead of reaching
users as an opaque "grpc service not ready".

Verified by driving the real runProtogen through the ROCm install sequence in
a venv harness: before, gencode 7.35.0 against runtime 6.33.6 (reproducing the
reported error verbatim); after, gencode 6.33.5 against runtime 6.33.6 and the
stub imports cleanly.

* fix(backends): regenerate protobuf stubs in the other backends that install after installRequirements

Same defect as the vllm change: installRequirements generates the stubs at the
end of its own run, so any backend that installs further packages afterwards can
have the protobuf runtime moved out from under stubs that were already written.
The gencode stamped into backend_pb2.py then exceeds the runtime that ships and
the backend dies at model load with "grpc service not ready".

fish-speech already had this bug and worked around the symptom: it forces
protobuf>=5.29.0 after installRequirements precisely because "transitive deps
(wandb, tensorboard) may downgrade protobuf to 3.x but our generated
backend_pb2.py requires protobuf 5+". Regenerating after the pin addresses the
cause rather than propping up the runtime to match stale stubs.

Applied to the backends whose post-installRequirements step resolves a
dependency graph and can therefore move protobuf:

  fish-speech             -e . plus an explicit protobuf install
  vibevoice               pip install . (with deps)
  llama-cpp-quantization  gguf / GGUF_PIP_SPEC
  trl                     gguf / GGUF_PIP_SPEC

Deliberately not applied to ace-step and chatterbox (both --no-deps, so the
dependency graph cannot change) or voxcpm (pins setuptools only). gguf does not
depend on protobuf today, but it resolves dependencies, and "this package does
not touch protobuf right now" is exactly the assumption that made the earlier
fix ineffective.

* fix(backends): resolve the protoc generator in a throwaway env so it cannot edit the backend's pinned deps

Installing grpcio-tools into the backend's own venv to generate the stubs also
drags its dependencies in: grpcio-tools 1.82.1 requires grpcio>=1.82.1, so a
backend that pinned grpcio==1.78.1 silently shipped 1.82.1 instead. Caught by
building the llama-cpp-quantization image and reading the versions back out of
the artifact:

  before   grpcio 1.82.1   (requirements.txt pins grpcio==1.78.1)
  after    grpcio 1.78.1   grpcio-tools absent from the venv entirely

Resolve the generator in a throwaway environment instead, still constrained to
the protobuf the backend ships so the gencode stays compatible. The backend's
dependency set is then exactly what its requirements files declared. protoc's
output is plain Python and carries no dependency on the interpreter that
produced it, so generating from a different env is safe; the import check still
runs under the backend's python, since that is the interpreter that has to load
the stubs at model load.

Verified on the rebuilt image: gencode 7.35.0, runtime protobuf 7.35.1, grpcio
back at its pinned 1.78.1, and the shipped stub imports cleanly against 7.35.1.

* fix(backends): bound the protoc generator by BOTH the installed grpcio and protobuf

The generated stubs impose two independent constraints, and every fix so far,
including the previous commit on this branch, satisfied one while violating the
other:

  backend_pb2.py       needs  protobuf runtime >= gencode
  backend_pb2_grpc.py  needs  installed grpcio >= grpcio-tools

Resolving the generator against protobuf alone picked grpcio-tools 1.82.1 for a
backend holding grpcio at 1.78.1, so the gencode was fine but the gRPC stub was
not:

  RuntimeError: The grpc package installed is at version 1.78.1, but the
  generated code in backend_pb2_grpc.py depends on grpcio>=1.82.1.

That is also why installing grpcio-tools into the backend venv appeared to work
earlier: it dragged grpcio up to match, which was load-bearing rather than the
regression it looked like. Isolating the generator removed the accidental fix
and exposed the missing constraint.

Bound grpcio-tools from both sides instead and let the resolver find the newest
version satisfying both. The protobuf ceiling makes it back off to an older
generator when the runtime trails, bounding the gencode; the grpcio ceiling
keeps the _grpc stub loadable. Resolved against the four real runtime pairs
observed in built images:

  grpcio 1.78.1 / protobuf 7.35.1  -> grpcio-tools 1.78.0, gencode 6.31.1  OK
  grpcio 1.78.0 / protobuf 6.33.6  -> grpcio-tools 1.78.0, gencode 6.31.1  OK
  grpcio 1.82.1 / protobuf 6.33.6  -> grpcio-tools 1.81.1, gencode 6.33.5  OK
  grpcio 1.82.1 / protobuf 7.35.1  -> grpcio-tools 1.82.1, gencode 7.35.0  OK

Also restore the import check to cover backend_pb2_grpc as well as backend_pb2.
Narrowing it to backend_pb2 is why the image build passed while CI failed: the
guard could not see the constraint that was actually broken.

Verified by running the CI sequence locally for llama-cpp-quantization, the
backend whose test failed:
  make -C backend/python/llama-cpp-quantization        -> exit 0
  make -C backend/python/llama-cpp-quantization test   -> exit 0, OK

d5d659bb65 fix(backends): pin grpcio-tools to installed grpcio in runProtogen (protobuf gencode mismatch) (#10735)
fix(backends): pin grpcio-tools to the installed grpcio in runProtogen

runProtogen installed grpcio-tools unpinned, so the protoc it bundles
stamped backend_pb2.py with the newest Protobuf gencode (7.35.0). When a
backend caps the protobuf runtime lower -- vLLM pins protobuf to 6.33.6 --
the import-time guarantee runtime >= gencode fails:

  google.protobuf.runtime_version.VersionError: Detected incompatible
  Protobuf Gencode/Runtime versions ... gencode 7.35.0 runtime 6.33.6

The backend crashes on `import backend_pb2` before it can serve, which
surfaces to the user as "grpc service not ready". It was mis-reported as a
ROCm/gfx1201 failure in #10718 but is not GPU-specific and affects every
vLLM variant (and any backend that caps protobuf below the latest gencode).

Pin grpcio-tools to the grpcio version the backend already installed --
they release in lockstep -- so the generated gencode stays in step with
the protobuf runtime. Falls back to unpinned when grpcio isn't present.

Closes #10718

16b2d4c807 fix(python-backend): make JIT subprocesses work on hosts of any size (#9679)
Two related runtime fixes for Python backends that JIT-compile CUDA
kernels at first model load (FlashInfer, PyTorch inductor, triton):

1. libbackend.sh: replace `source ${EDIR}/venv/bin/activate` with a
   minimal manual setup (_activateVenv: export VIRTUAL_ENV, prepend
   PATH, unset PYTHONHOME) computed from $EDIR at runtime. `uv venv`
   and `python -m venv` both bake the create-time absolute path into
   bin/activate (e.g. VIRTUAL_ENV='/vllm/venv' from the Docker build
   stage), so sourcing activate on a relocated venv — copied out of
   the build container and unpacked at an arbitrary backend dir —
   prepends a stale, non-existent path to $PATH. Pip-installed CLI
   tools (e.g. ninja, used by FlashInfer's NVFP4 GEMM JIT) are then
   never found and the load aborts with FileNotFoundError. Doing the
   env setup ourselves matches what `uv run` does internally and
   sidesteps the relocation problem entirely. Generic — every Python
   backend benefits.

2. vllm/run.sh: replace ninja's default -j$(nproc)+2 with an adaptive
   MAX_JOBS = min(nproc, (MemAvailable-4)/4). Each concurrent
   nvcc/cudafe++ peaks at multiple GiB; the default OOM-kills on
   memory-tight hosts (e.g. a 16 GiB desktop loading a 27B NVFP4
   model) but underutilises 100-core / 1 TB boxes. User-set MAX_JOBS
   still wins. Also pin NVCC_THREADS=2 unless overridden.

016da02845 feat: refactor shared helpers and enhance MLX backend functionality (#9335)
* refactor(backends): extract python_utils + add mlx_utils shared helpers

Move parse_options() and messages_to_dicts() out of vllm_utils.py into a
new framework-agnostic python_utils.py, and re-export them from vllm_utils
so existing vllm / vllm-omni imports keep working.

Add mlx_utils.py with split_reasoning() and parse_tool_calls() — ported
from mlx_vlm/server.py's process_tool_calls. These work with any
mlx-lm / mlx-vlm tool module (anything exposing tool_call_start,
tool_call_end, parse_tool_call). Used by the mlx and mlx-vlm backends in
later commits to emit structured ChatDelta.tool_calls without
reimplementing per-model parsing.

Shared smoke tests confirm:
- parse_options round-trips bool/int/float/string
- vllm_utils re-exports are identity-equal to python_utils originals
- mlx_utils parse_tool_calls handles <tool_call>...</tool_call> with a
  shim module and produces a correctly-indexed list with JSON arguments
- mlx_utils split_reasoning extracts <think> blocks and leaves clean
  content

* feat(mlx): wire native tool parsers + ChatDelta + token usage + logprobs

Bring the MLX backend up to the same structured-output contract as vLLM
and llama.cpp: emit Reply.chat_deltas so the OpenAI HTTP layer sees
tool_calls and reasoning_content, not just raw text.

Key insight: mlx_lm.load() returns a TokenizerWrapper that already auto-
detects the right tool parser from the model's chat template
(_infer_tool_parser in mlx_lm/tokenizer_utils.py). The wrapper exposes
has_tool_calling, has_thinking, tool_parser, tool_call_start,
tool_call_end, think_start, think_end — no user configuration needed,
unlike vLLM.

Changes in backend/python/mlx/backend.py:

- Imports: replace inline parse_options / messages_to_dicts with the
  shared helpers from python_utils. Pull split_reasoning / parse_tool_calls
  from the new mlx_utils shared module.
- LoadModel: log the auto-detected has_tool_calling / has_thinking /
  tool_parser_type for observability. Drop the local is_float / is_int
  duplicates.
- _prepare_prompt: run request.Messages through messages_to_dicts so
  tool_call_id / tool_calls / reasoning_content survive the conversion,
  and pass tools=json.loads(request.Tools) + enable_thinking=True (when
  request.Metadata says so) to apply_chat_template. Falls back on
  TypeError for tokenizers whose template doesn't accept those kwargs.
- _build_generation_params: return an additional (logits_params,
  stop_words) pair. Maps RepetitionPenalty / PresencePenalty /
  FrequencyPenalty to mlx_lm.sample_utils.make_logits_processors and
  threads StopPrompts through to post-decode truncation.
- New _tool_module_from_tokenizer / _finalize_output / _truncate_at_stop
  helpers. _finalize_output runs split_reasoning when has_thinking is
  true and parse_tool_calls (using a SimpleNamespace shim around the
  wrapper's tool_parser callable) when has_tool_calling is true, then
  extracts prompt_tokens, generation_tokens and (best-effort) logprobs
  from the last GenerationResponse chunk.
- Predict: use make_logits_processors, accumulate text + last_response,
  finalize into a structured Reply carrying chat_deltas,
  prompt_tokens, tokens, logprobs. Early-stops on user stop sequences.
- PredictStream: per-chunk Reply still carries raw message bytes for
  back-compat but now also emits chat_deltas=[ChatDelta(content=delta)].
  On loop exit, emit a terminal Reply with structured
  reasoning_content / tool_calls / token counts / logprobs — so the Go
  side sees tool calls without needing the regex fallback.
- TokenizeString RPC: uses the TokenizerWrapper's encode(); returns
  length + tokens or FAILED_PRECONDITION if the model isn't loaded.
- Free RPC: drops model / tokenizer / lru_cache, runs gc.collect(),
  calls mx.metal.clear_cache() when available, and best-effort clears
  torch.cuda as a belt-and-suspenders.

* feat(mlx-vlm): mirror MLX parity (tool parsers + ChatDelta + samplers)

Same treatment as the MLX backend: emit structured Reply.chat_deltas,
tool_calls, reasoning_content, token counts and logprobs, and extend
sampling parameter coverage beyond the temp/top_p pair the backend
used to handle.

- Imports: drop the inline is_float/is_int helpers, pull parse_options /
  messages_to_dicts from python_utils and split_reasoning /
  parse_tool_calls from mlx_utils. Also import make_sampler and
  make_logits_processors from mlx_lm.sample_utils — mlx-vlm re-uses them.
- LoadModel: use parse_options; call mlx_vlm.tool_parsers._infer_tool_parser
  / load_tool_module to auto-detect a tool module from the processor's
  chat_template. Stash think_start / think_end / has_thinking so later
  finalisation can split reasoning blocks without duck-typing on each
  call. Logs the detected parser type.
- _prepare_prompt: convert proto Messages via messages_to_dicts (so
  tool_call_id / tool_calls survive), pass tools=json.loads(request.Tools)
  and enable_thinking=True to apply_chat_template when present, fall
  back on TypeError for older mlx-vlm versions. Also handle the
  prompt-only + media and empty-prompt + media paths consistently.
- _build_generation_params: return (max_tokens, sampler_params,
  logits_params, stop_words). Maps repetition_penalty / presence_penalty /
  frequency_penalty and passes them through make_logits_processors.
- _finalize_output / _truncate_at_stop: common helper used by Predict
  and PredictStream to split reasoning, run parse_tool_calls against the
  auto-detected tool module, build ToolCallDelta list, and extract token
  counts + logprobs from the last GenerationResult.
- Predict / PredictStream: switch from mlx_vlm.generate to mlx_vlm.stream_generate
  in both paths, accumulate text + last_response, pass sampler and
  logits_processors through, emit content-only ChatDelta per streaming
  chunk followed by a terminal Reply carrying reasoning_content,
  tool_calls, prompt_tokens, tokens and logprobs. Non-streaming Predict
  returns the same structured Reply shape.
- New helper _collect_media extracted from the duplicated base64 image /
  audio decode loop.
- New TokenizeString RPC using the processor's tokenizer.encode and
  Free RPC that drops model/processor/config, runs gc + Metal cache
  clear + best-effort torch.cuda cache clear.

* feat(importer/mlx): auto-set tool_parser/reasoning_parser on import

Mirror what core/gallery/importers/vllm.go does: after applying the
shared inference defaults, look up the model URI in parser_defaults.json
and append matching tool_parser:/reasoning_parser: entries to Options.

The MLX backends auto-detect tool parsers from the chat template at
runtime so they don't actually consume these options — but surfacing
them in the generated YAML:
  - keeps the import experience consistent with vllm
  - gives users a single visible place to override
  - documents the intended parser for a given model family

* test(mlx): add helper unit tests + TokenizeString/Free + e2e make targets

- backend/python/mlx/test.py: add TestSharedHelpers with server-less
  unit tests for parse_options, messages_to_dicts, split_reasoning and
  parse_tool_calls (using a SimpleNamespace shim to fake a tool module
  without requiring a model). Plus test_tokenize_string and test_free
  RPC tests that load a tiny MLX-quantized Llama and exercise the new
  RPCs end-to-end.

- backend/python/mlx-vlm/test.py: same helper unit tests + cleanup of
  the duplicated import block at the top of the file.

- Makefile: register BACKEND_MLX and BACKEND_MLX_VLM (they were missing
  from the docker-build-target eval list — only mlx-distributed had a
  generated target before). Add test-extra-backend-mlx and
  test-extra-backend-mlx-vlm convenience targets that build the
  respective image and run tests/e2e-backends with the tools capability
  against mlx-community/Qwen2.5-0.5B-Instruct-4bit. The MLX backend
  auto-detects the tool parser from the chat template so no
  BACKEND_TEST_OPTIONS is needed (unlike vllm).

* fix(libbackend): don't pass --copies to venv unless PORTABLE_PYTHON=true

backend/python/common/libbackend.sh:ensureVenv() always invoked
'python -m venv --copies', but macOS system python (and some other
builds) refuses with:

    Error: This build of python cannot create venvs without using symlinks

--copies only matters when _makeVenvPortable later relocates the venv,
which only happens when PORTABLE_PYTHON=true. Make --copies conditional
on that flag and fall back to default (symlinked) venv otherwise.

Caught while bringing up the mlx backend on Apple Silicon — the same
build path is used by every Python backend with USE_PIP=true.

* fix(mlx): support mlx-lm 0.29.x tool calling + drop deprecated clear_cache

The released mlx-lm 0.29.x ships a much simpler tool-calling API than
HEAD: TokenizerWrapper detects the <tool_call>...</tool_call> markers
from the tokenizer vocab and exposes has_tool_calling /
tool_call_start / tool_call_end, but does NOT expose a tool_parser
callable on the wrapper and does NOT ship a mlx_lm.tool_parsers
subpackage at all (those only exist on main).

Caught while running the smoke test on Apple Silicon with the
released mlx-lm 0.29.1: tokenizer.tool_parser raised AttributeError
(falling through to the underlying HF tokenizer), so
_tool_module_from_tokenizer always returned None and tool calls slipped
through as raw <tool_call>...</tool_call> text in Reply.message instead
of being parsed into ChatDelta.tool_calls.

Fix: when has_tool_calling is True but tokenizer.tool_parser is missing,
default the parse_tool_call callable to json.loads(body.strip()) — that's
exactly what mlx_lm.tool_parsers.json_tools.parse_tool_call does on HEAD
and covers the only format 0.29 detects (<tool_call>JSON</tool_call>).
Future mlx-lm releases that ship more parsers will be picked up
automatically via the tokenizer.tool_parser attribute when present.

Also tighten the LoadModel logging — the old log line read
init_kwargs.get('tool_parser_type') which doesn't exist on 0.29 and
showed None even when has_tool_calling was True. Log the actual
tool_call_start / tool_call_end markers instead.

While here, switch Free()'s Metal cache clear from the deprecated
mx.metal.clear_cache to mx.clear_cache (mlx >= 0.30), with a
fallback for older releases. Mirrored to the mlx-vlm backend.

* feat(mlx-distributed): mirror MLX parity (tool calls + ChatDelta + sampler)

Same treatment as the mlx and mlx-vlm backends: emit Reply.chat_deltas
with structured tool_calls / reasoning_content / token counts /
logprobs, expand sampling parameter coverage beyond temp+top_p, and
add the missing TokenizeString and Free RPCs.

Notes specific to mlx-distributed:

- Rank 0 is the only rank that owns a sampler — workers participate in
  the pipeline-parallel forward pass via mx.distributed and don't
  re-implement sampling. So the new logits_params (repetition_penalty,
  presence_penalty, frequency_penalty) and stop_words apply on rank 0
  only; we don't need to extend coordinator.broadcast_generation_params,
  which still ships only max_tokens / temperature / top_p to workers
  (everything else is a rank-0 concern).
- Free() now broadcasts CMD_SHUTDOWN to workers when a coordinator is
  active, so they release the model on their end too. The constant is
  already defined and handled by the existing worker loop in
  backend.py:633 (CMD_SHUTDOWN = -1).
- Drop the locally-defined is_float / is_int / parse_options trio in
  favor of python_utils.parse_options, re-exported under the module
  name for back-compat with anything that imported it directly.
- _prepare_prompt: route through messages_to_dicts so tool_call_id /
  tool_calls / reasoning_content survive, pass tools=json.loads(
  request.Tools) and enable_thinking=True to apply_chat_template, fall
  back on TypeError for templates that don't accept those kwargs.
- New _tool_module_from_tokenizer (with the json.loads fallback for
  mlx-lm 0.29.x), _finalize_output, _truncate_at_stop helpers — same
  contract as the mlx backend.
- LoadModel logs the auto-detected has_tool_calling / has_thinking /
  tool_call_start / tool_call_end so users can see what the wrapper
  picked up for the loaded model.
- backend/python/mlx-distributed/test.py: add the same TestSharedHelpers
  unit tests (parse_options, messages_to_dicts, split_reasoning,
  parse_tool_calls) that exist for mlx and mlx-vlm.

to the correct ROCm wheel index and --index-strategy unsafe-best-match
(set in libbackend.sh) ensures the ROCm variant is preferred.

Applies the same fix as 7f5d72e8 (which resolved this for +cpu) across
all 14 hipblas requirements files.

* revert: scope hipblas suffix fix to whisperx only

Reverts changes to non-whisperx hipblas requirements files per
maintainer review — other backends are building fine with the +rocm
local version suffix.

fd53978a7b feat: package GPU libraries inside backend containers for unified base image (#7891)
* Initial plan

* Add GPU library packaging for isolated backend environments

- Create scripts/build/package-gpu-libs.sh for packaging CUDA, ROCm, SYCL, and Vulkan libraries
- Update llama-cpp, whisper, stablediffusion-ggml package.sh to include GPU libraries
- Update Dockerfile.python to package GPU libraries into Python backends
- Update libbackend.sh to set LD_LIBRARY_PATH for GPU library loading

Co-authored-by: mudler <2420543+mudler@users.noreply.github.com>

* Address code review feedback: fix variable consistency and quoting

Co-authored-by: mudler <2420543+mudler@users.noreply.github.com>

* Fix code review issues: improve glob handling and remove redundant variable

Co-authored-by: mudler <2420543+mudler@users.noreply.github.com>

* Simplify main Dockerfile and workflow to use unified base image

- Remove GPU-specific driver installation from Dockerfile (CUDA, ROCm, Vulkan, Intel)
- Simplify image.yml workflow to build single unified base image for linux/amd64 and linux/arm64
- GPU libraries are now packaged in individual backend containers
