Usage

Basic check

trtcheck model.onnx

Exit code is 1 if conversion is unlikely, 0 otherwise. Wire that into CI to catch regressions at PR time.

Common flags

# target a specific TensorRT version
trtcheck model.onnx --target-trt 8.6

# machine-readable output for CI
trtcheck model.onnx --format json --output report.json

# self-contained HTML report
trtcheck model.onnx --format html --output report.html

# filter to blockers only
trtcheck model.onnx --severity critical

# compare two ONNX files
trtcheck before.onnx after.onnx --diff --format html --output diff.html

# auto-fix simple cases (INT64 indices, UINT8 inputs after Cast, etc.)
trtcheck model.onnx --fix --dry-run --output fixed.onnx
trtcheck model.onnx --fix --output fixed.onnx

All flags

Flag	Default	Meaning
--target-trt	10.3	TensorRT version to check against
--format	console	console, json, or html
--output	(stdout)	Write the report to this path
--severity	info	Minimum severity to include
--verbose	off	Lowers severity threshold to info
--diff	off	Compare two ONNX files
--force	off	Allow --output to overwrite existing files
--max-model-size	500	Refuse to load ONNX files larger than this (MB)
--fix	off	Apply built-in fixers; writes to --output
--dry-run	off	With --fix, print changes without writing

CI integration

A composite GitHub Action ships in this repo. See the README for the dual-workflow setup that posts a sticky PR comment when ONNX files change.
