ci(trtllm): install pre-release wheel from PyPI instead of building from source#1501key4ng wants to merge 2 commits into
Conversation
…rom source PR #11037 (gRPC serve) and the Harmony parser fixes that motivated the source build (#12045, #12467) are all included in tensorrt-llm 1.3.0rc14 on PyPI. Pinning to the published pre-release saves ~30 min of CMake compile time per CI run and removes the brittle wheel-cache dance whose key was evicted after 7 days of inactivity. Drop the cached-wheel + source-build branches from ci_install_trtllm.sh and the now-redundant cache restore/save steps from the composite action. The runtime apt deps, NCCL pin, cu130 torch index URL, and LD_LIBRARY_PATH setup are preserved. Signed-off-by: key4ng <rukeyang@gmail.com>

Do not swallow smoke-test failures in CI verification.
Line 88 converts a failed serve --help check into a warning, allowing the job to pass despite a broken TRT-LLM install. Remove the || echo fallback to make this check fail hard.
Proposed fix
- python3 -m tensorrt_llm.commands.serve serve --help 2>&1 | head -20 || echo "WARNING: serve --help failed"
+ python3 -m tensorrt_llm.commands.serve serve --help 2>&1 | head -20📝 Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In the clean CI runners this command only searches PyPI plus the PyTorch CUDA index, but the PyPI metadata for tensorrt-llm==1.3.0rc14 currently exposes only the tiny source distribution tensorrt_llm-1.3.0rc14.tar.gz and no prebuilt wheel. That means this no longer installs the compiled TensorRT-LLM artifact the next verification imports (tensorrt_llm.commands.serve), so every setup-trtllm job will fail or install an unusable placeholder unless the NVIDIA wheel index/direct wheel is included.
Useful? React with 👍 / 👎.

Code Review
This pull request refactors the CI pipeline to install TensorRT-LLM directly from a PyPI pre-release wheel, significantly reducing build times by removing the need to compile from source and manage local wheel caches. The changes simplify scripts/ci_install_trtllm.sh by stripping out source cloning, CMake patching, and build-specific dependencies. Feedback was provided to improve the robustness of LD_LIBRARY_PATH exports by using conditional expansion to avoid leading or trailing colons, which can pose security risks by accidentally including the current working directory in the library search path.
| source .venv/bin/activate | ||
| fi | ||

| export LD_LIBRARY_PATH="${CUDA_HOME}/lib64:${CUDA_HOME}/extras/CUPTI/lib64:${LD_LIBRARY_PATH:-}" |

The current construction of LD_LIBRARY_PATH can result in a trailing colon if the variable was previously empty or unset. In shell, a trailing or leading colon in LD_LIBRARY_PATH is interpreted as including the current working directory (.), which is generally considered a security risk and can lead to unexpected library resolution. It is safer to use the ${VAR:+:${VAR}} syntax to only append the colon if the variable is already non-empty.

Similar to the previous comment, this construction can introduce a leading or trailing colon if LD_LIBRARY_PATH was empty. Using the conditional expansion syntax ensures a clean path list without accidentally including the current directory in the search path.
| export LD_LIBRARY_PATH="${NVIDIA_LIB_DIRS}:${LD_LIBRARY_PATH:-}" | |
| export LD_LIBRARY_PATH="${NVIDIA_LIB_DIRS}${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}" |
PyPI only ships the tensorrt-llm source tarball, so a plain pip install tensorrt-llm==1.3.0rc14 triggers a full source build — defeating the purpose of switching off the build_wheel.py path. The pre-built linux_x86_64 wheel (2.75 GB) lives at https://pypi.nvidia.com/tensorrt-llm/, which pip needs as an extra index to resolve. Signed-off-by: key4ng <rukeyang@gmail.com>

Description
Problem
The
e2e-1gpu-chat (trtllm)CI step has been hanging for ~30 min on every PR because Setup TRT-LLM backend falls into the from-source build path. Root cause:.github/actions/setup-trtllm/action.ymlkeys the wheel cache onhashFiles('scripts/ci_install_trtllm.sh').trtllm-wheel-*(out of 2476 total).main, runsgit lfs pull, and invokesscripts/build_wheel.py --cuda_architectures "90-real"— a full CMake C++ compile.mainitself has a warm cache.Example: https://github.com/lightseekorg/smg/actions/runs/25981764002/job/76372164127 stuck >34 min on "Setup TRT-LLM backend" while every other step was pending.
Solution
Install the published
tensorrt-llm==1.3.0rc14pre-release wheel from PyPI. Verification that the fixes which motivated the source build are present in rc14:Saves ~30 min/run and removes the brittle wheel-cache dependency entirely.

Caveats

CI must run the trtllm e2e job on this PR. Specifically:
e2e-1gpu-chat (trtllm) / runpasses.Setup TRT-LLM backendcompletes in well under 30 min (target: a few minutes, dominated by apt + pip download).python3 -m tensorrt_llm.commands.serve serve --helpsmoke test still succeeds (proves PR #11037 gRPC serve is present in the installed wheel).Checklist
