Summary by CodeRabbit

  • New Features

    • Added a new command-line option, --trust-remote-code, allowing users to control remote code trust when loading tokenizers. Defaults to False.
  • Bug Fixes

    • Improved tokenizer loading and validation to enhance reliability and compatibility with updated dependencies.

Description

This PR adds the --trust-remote-code option to dataset preparation. It adds a click flag and augments the RootArgs model class to use a model validator so that it can initialize the tokenizer with other options in the instance.

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.

📝 Walkthrough

Walkthrough

The code updates the RootArgs model in benchmarks/cpp/prepare_dataset.py to use Pydantic's model_validator instead of the deprecated field_validator for tokenizer validation. It adds a new trust_remote_code boolean field, updates the tokenizer loading logic, and extends the CLI with a --trust-remote-code flag.

Changes

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:

19-19: LGTM! Proper migration from deprecated Pydantic API.

The import correctly updates from the deprecated field_validator to the modern model_validator, which aligns with the validator method changes in the class.


31-31: LGTM! Secure default for remote code trust.

The new field properly defaults to False, following security best practices by not trusting remote code unless explicitly enabled.


35-36: LGTM! Correct migration to model_validator.

The decorator and method signature correctly implement the modern Pydantic validation pattern using model_validator(mode='after').


38-41: LGTM! Proper integration of trust_remote_code parameter.

The tokenizer loading correctly incorporates the new trust_remote_code field, enhancing security control over remote code execution.


47-49: LGTM! Correct model validator return pattern.

The method properly assigns the tokenizer instance to self.tokenizer and returns self, which is the correct pattern for Pydantic model validators.


108-109: LGTM! Consistent parameter passing.

The new trust_remote_code parameter is correctly passed to the RootArgs constructor, following the established pattern.

35-49: LGTM: Proper Pydantic v2 migration with minor type consideration.

The migration from field_validator to model_validator(mode='after') is correctly implemented. The logic properly uses both self.tokenizer and self.trust_remote_code fields to load the tokenizer with the new parameter.

Consider updating the type annotation for the tokenizer field to reflect that it becomes a tokenizer instance after validation, or document this behavior for clarity.


43-45: Fix line length violation per static analysis.

Line 44 exceeds the 120-character limit. Consider breaking the error message for better readability.

19-19: LGTM: Import updated correctly for Pydantic model validator.

The addition of model_validator to the import is necessary for the migration from the deprecated field_validator.


31-31: LGTM: Security-conscious field addition.

The new trust_remote_code field with False default is well-designed, requiring explicit opt-in for security.


88-92: LGTM: Well-designed CLI option with environment variable support.

The --trust-remote-code flag is properly implemented with security-conscious defaults and flexible environment variable support.


109-110: LGTM: Constructor correctly updated with new parameter.

The trust_remote_code parameter is properly passed from CLI to the RootArgs constructor.
