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.

Details

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.

33-36: LGTM - Import addition is correct.

The addition of get_device_count to the import statement follows the existing import pattern and is necessary for the device availability checks added later in the test functions.


2116-2116: LGTM - Tensor parallelism parameterization added correctly.

The tp_size parameterization with values [1, 2] and appropriate IDs ["tp1", "tp2"] is well-structured and follows pytest conventions. This enables testing both single-GPU and dual-GPU scenarios.


2133-2133: LGTM - Function signature updated correctly.

The function signature has been properly updated to include the tp_size parameter, maintaining consistency with the parameterization decorator.


2137-2140: LGTM - Device availability check implemented correctly.

The device count validation correctly skips the test when insufficient devices are available for the requested tp_size. The skip message is clear and informative, helping users understand why the test was skipped.


2257-2257: LGTM - Command line argument added correctly.

The tp_size parameter is properly passed to the command line execution via f"--tp_size={tp_size}", maintaining consistency with the existing argument passing pattern.


2333-2333: LGTM - Consistent argument passing in functionality test.

The tp_size argument is also correctly passed in the functionality test section, ensuring consistency across all test invocations within the function.


2342-2342: LGTM - Consistent parameterization pattern.

The second test function follows the same parameterization pattern as the first, maintaining consistency across the codebase.


2344-2345: LGTM - Function signature maintained correctly.

The function signature has been properly updated to include the tp_size parameter while preserving the original parameter order.


2346-2349: LGTM - Consistent device availability check.

The device count validation is implemented identically to the first function, ensuring consistent behavior and error messaging across both test functions.


2422-2422: LGTM - Command line argument integration.

The tp_size parameter is correctly integrated into the command line arguments, following the same pattern established in the first test function.

2505-2522: Fix line length violation and improve readability.

The output validation logic is sound with appropriate match ratios and keyword checking. However, Line 2510 exceeds the 120-character limit.

Apply this diff to fix the line length issue:

-        assert obs_match_ratio >= match_ratio, f"Incorrect output!\nGenerated \"{prompt_output}\"\nExpected keywords \"{prompt_keywords}\"\n Matched keywords: {matches}\n Observed match ratio {obs_match_ratio} below threshold {match_ratio}"

2421-2429: LGTM: Well-structured test function with appropriate decorators.

The test function properly uses pytest decorators to ensure hardware requirements (2+ GPUs, 80GB+ memory) and is correctly parameterized over the three NIM-required VLM models mentioned in the PR objectives.


2430-2473: LGTM: Well-organized test data setup.

The test data structure is clean and well-organized with appropriate paths, prompts, and model-specific expected keywords. The use of llm_models_root() and structured dictionaries makes the test data maintainable and clear.


2475-2504: LGTM: Proper command construction with model-specific configurations.

The command building logic correctly sets --tp_size=2 for multi-GPU testing and properly handles model-specific configurations:

  • Gemma3 gets appropriate flashinfer backend settings
  • Phi-4 gets LoRA loading and sequence length configurations

The conditional logic is clear and maintainable.

Python local variables should use snake_case. Prefix k for variable names that start with a number (e.g., k_99th_percentile).
Python global variables should use upper snake_case and prefix G (e.g., G_MY_GLOBAL).
Python constants should use upper snake_case (e.g., MY_CONSTANT).
Avoid shadowing variables declared in an outer scope in Python.
Initialize all externally visible members of a Python class in the constructor.
For interfaces that may be used outside a Python file, prefer docstrings over comments.
Comments in Python should be reserved for code within a function, or interfaces that are local to a file.
Use Google style docstrings for Python classes and functions, which can be parsed by Sphinx.
Attributes and variables in Python can be documented inline; attribute docstrings will be rendered under the class docstring.
Avoid using reflection in Python when functionality can be easily achieved without it.
When using try-except blocks in Python, limit the except to the smallest set of errors possible.
When using try-except blocks to handle multiple possible variable types in Python, keep the body of the try as small as possible, using the else block to implement the logic.

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: 2025-08-01T15:14:45.673Z
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.

2421-2429: LGTM! Test function structure is well-designed.

The test function follows established patterns from existing multimodal tests and includes appropriate pytest markers for multi-GPU requirements. The parametrization covers the three VLM models required by NIM as mentioned in the PR objectives.


2430-2448: LGTM! Test setup follows established conventions.

The accuracy inputs definition is consistent with existing multimodal tests and appropriately focuses on image modality for the 2-GPU test scenario.


2450-2473: LGTM! Expected keywords are well-defined for accuracy validation.

The expected keywords for each model are specific and relevant to the test prompts, providing a solid foundation for accuracy assertions.


2475-2504: LGTM! Command construction with model-specific configurations is appropriate.

The command construction properly includes the --tp_size=2 parameter for multi-GPU testing and implements model-specific configurations that match the patterns used in the existing test_ptp_quickstart_multimodal function.
