GitHub Bot Help

/bot [-h] ['run', 'kill', 'skip', 'reuse-pipeline'] ...

Provide a user friendly way for developers to interact with a Jenkins server.

Run /bot [-h|--help] to print this help message.

See details below for each supported subcommand.

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental)]

Launch build/test pipelines. All previously running jobs will be killed.

--reuse-test (optional)pipeline-id (OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.

--disable-reuse-test (OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.

--disable-fail-fast (OPTIONAL) : Disable fail fast on build/tests/infra failures.

--skip-test (OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx" (OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: Does NOT update GitHub check status.

--gpu-type "A30, H100_PCIe" (OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.

--test-backend "pytorch, cpp" (OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.

--only-multi-gpu-test (OPTIONAL) : Only run the multi-GPU tests. Note: Does NOT update GitHub check status.

--disable-multi-gpu-test (OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.

--add-multi-gpu-test (OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline.

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".

--detailed-log (OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.

--debug (OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose. Note: Specify exactly one stage in the stage-list parameter to access the appropriate container environment. Note: Does NOT update GitHub check status.

For guidance on mapping tests to stage names, see docs/source/reference/ci-overview.md
and the scripts/test_to_stage_mapping.py helper.

kill

kill

Kill all running builds associated with pull request.

skip

skip --comment COMMENT

Skip testing for latest commit on pull request. --comment "Reason for skipping build/test" is required. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

reuse-pipeline

reuse-pipeline

Reuse a previous pipeline to validate current commit. This action will also kill all currently running builds associated with the pull request. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)
Check name Status Explanation Resolution
Description Check ⚠️ Warning The PR description contains only the repository PR template and helper text and does not include a filled "Description" or "Test Coverage" section explaining what was changed, why, or how the change was validated. Because the body is the template rather than a concrete summary, reviewers cannot verify scope, list of modified files, or test coverage from the PR itself. Although the raw_summary indicates docs-only link fixes, the PR description is incomplete relative to the repository's required template. Please replace the template placeholders with a concise Description that lists the files changed and explains why links were updated, a Test Coverage section stating what CI/tests were run or "none" if docs-only, and a short impact statement confirming no runtime/API changes. Add any related issue/JIRA references and note any reviewer verification steps (for example, link rendering or link-check confirmation). After updating the PR description with these details, re-request review.
✅ Passed checks (2 passed)
Check name Status Explanation
Title Check ✅ Passed The title "[None][doc] Fix broken links in markdown files" accurately and concisely summarizes the primary change in this changeset — correcting broken links across multiple Markdown docs as shown in the raw_summary (CONTRIBUTING.md, README.md, docs/*). It follows the repository's expected title format by including the ticket placeholder and the [doc] type tag and avoids extraneous detail. A reviewer scanning history will understand the main intent from this title alone.
Docstring Coverage ✅ Passed No functions found in the changes. Docstring coverage check skipped.

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

  • Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
  • Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

Timestamp: 2025-08-21T00:16:56.457Z
Learning: TensorRT-LLM container release tags in documentation should only reference published NGC container images. The README badge version may be ahead of the actual published container versions.

Timestamp: 2025-08-01T15:14:45.673Z
Learning: In TensorRT-LLM, examples directory can have different dependency versions than the root requirements.txt file. Version conflicts between root and examples dependencies are acceptable because examples are designed to be standalone and self-contained.

Timestamp: 2025-08-06T13:58:07.506Z
Learning: In TensorRT-LLM, test files (files under tests/ directories) do not require NVIDIA copyright headers, unlike production source code files. Test files typically start directly with imports, docstrings, or code.

Timestamp: 2025-07-28T17:06:08.621Z
Learning: In TensorRT-LLM testing, it's common to have both CLI flow tests (test_cli_flow.py) and PyTorch API tests (test_llm_api_pytorch.py) for the same model. These serve different purposes: CLI flow tests validate the traditional command-line workflow, while PyTorch API tests validate the newer LLM API backend. Both are legitimate and should coexist.

Timestamp: 2025-08-11T20:09:24.389Z
Learning: In the TensorRT-LLM test infrastructure, the team prefers simple, direct solutions (like hard-coding directory traversal counts) over more complex but robust approaches when dealing with stable directory structures. They accept the maintenance cost of updating tests if the layout changes.

Timestamp: 2025-09-09T09:40:45.658Z
Learning: In TensorRT-LLM test lists, it's common and intentional for the same test to appear in multiple test list files when they serve different purposes (e.g., llm_function_core.txt for comprehensive core functionality testing and llm_function_core_sanity.txt for quick sanity checks). This duplication allows tests to be run in different testing contexts.

Timestamp: 2025-08-26T09:49:04.956Z
Learning: In TensorRT-LLM test configuration files, the test scheduling system handles wildcard matching with special rules that prevent duplicate test execution even when the same tests appear in multiple yaml files with overlapping GPU wildcards (e.g., "*b200*" and "*gb200*").

Timestamp: 2025-08-27T16:59:12.325Z
Learning: In FP8 quantized linear layers, bias should be kept in high precision (typically float32) rather than being quantized to FP8 or cast to half precision, as bias is added after the matrix multiplication and high precision bias helps maintain numerical accuracy.

docs/source/legacy/torch.md (4)

29-31: Developer Guide links LGTM

Targets under ../torch and ../models appear consistent with the new structure.


34-37: Key Components links LGTM

Paths to ../features/attention.md and ../torch/* components look consistent.


22-26: Feature links look correct after reparenting — no changes required

Verified files exist at docs/source/features/sampling.md, docs/source/features/quantization.md, docs/source/torch/features/overlap_scheduler.md, docs/source/torch/features/feature_combination_matrix.md.


44-44: Broken relative path — update link to ../features/auto_deploy/auto-deploy.md

docs/source/legacy/torch.md (line 44): "./torch/auto_deploy/auto-deploy.md" resolves to docs/source/legacy/torch/..., but the file exists at docs/source/features/auto_deploy/auto-deploy.md — change the link to ../features/auto_deploy/auto-deploy.md.

Likely an incorrect or invalid review comment.

docs/source/developer-guide/perf-benchmarking.md (3)

70-71: Verified: Performance Overview link resolves to existing doc.
../legacy/performance/perf-overview.md → docs/source/legacy/performance/perf-overview.md (file present).


11-11: Anchor exists — no action required

Header "Throughput Measurements" is present in docs/source/legacy/performance/perf-overview.md (line 17), so ../legacy/performance/perf-overview.md#throughput-measurements is valid.


18-19: Link target exists — no action required.

docs/source/legacy/advanced/gpt-attention.md defines (inflight-batching)= and a "## In-flight Batching" section, so ../legacy/advanced/gpt-attention.md#in-flight-batching resolves.

CONTRIBUTING.md (1)

139-151: Align example stack trace path to ./tests/unittest/api_stability

CONTRIBUTING.md still references the old tests/api_stability path; update it to the new path (tests/unittest/api_stability exists).

- tests/api_stability/test_api_stability.py:241: AssertionError
+ tests/unittest/api_stability/test_api_stability.py:241: AssertionError
README.md (1)

15-15: Verify updated Performance link and anchor — confirmed

docs/source/legacy/performance/perf-overview.md exists and contains the heading "## Throughput Measurements" (line 17).

we don't need to modify the invalid links under legacy folder since it's meaningless.
Meanwhile, we're not recommend to refer the docs under legacy folder.
I just cherry-pick some of changes this PR into #7933
Let's hold this PR until mass integration PR #7928 done.
