Check and format Python code in Megatron-LM using autoformat.sh and its linting tools. Apply project rules for imports, type hints, documentation, naming, and line length when preparing changes for a pull request.
Linting and formatting for Megatron-LM. Covers running autoformat.sh, tools (ruff, black, isort, pylint, mypy), and code style rules.
Review the instructions the agent will receive before you install.
Run before opening a PR:
# Check mode (no changes applied)
BASE_REF=main CHECK_ONLY=true SKIP_DOCS=false bash tools/autoformat.sh
# Fix mode
BASE_REF=main CHECK_ONLY=false bash tools/autoformat.sh
Tools invoked: black, isort, pylint, ruff, mypy.
After editing imports in any Python files, always run uv run isort on those
files before committing:
uv run isort <file1>.py <file2>.py
Inside the container:
uv sync --locked --only-group linting
This installs ruff, black, isort, pylint — the same tools used by
tools/autoformat.sh and CI's linting job.

Move pandas-style table processing to NVIDIA GPUs using cuDF. Choose minimal-change acceleration or explicit GPU code, handle joins and aggregations, compare results with pandas, and use dask-cuDF when data exceeds GPU memory.
Customize NVIDIA Nemotron Voice Agent’s Generic Pipecat example for appointment scheduling, five-field patient intake, or a custom healthcare conversation. Build prompts and tool handlers without a separate backend, then validate conversation behavior, services, and voice interaction.
Calibrate live cameras by recording their RTSP video streams through VIOS and processing the clips with AutoMagicCalib. The workflow imports settings and alignment files, checks readiness, tracks calibration progress, and retrieves results.
Test a running AMC service with the bundled four-camera warehouse dataset. Run camera calibration from upload to completion, then check distance and image projection errors against ground-truth data to verify the installation.
Calibrate multiple cameras from recorded MP4 files through the AutoMagicCalib REST API. The skill handles project creation, uploads, input verification, progress checks, and evaluation when reference data is supplied, with optional VGGT refinement.
Set up AutoMagicCalib from NGC release containers using Docker Compose. The skill handles registry authentication, port and path configuration, optional VGGT model download, service startup, and readiness checks for the backend and web interface.
