HaoLine (好线)

Universal Model Inspector — See what's really inside your models.

A graph-level analysis tool that inspects neural network architectures (ONNX, PyTorch, TensorFlow, TensorRT), computes static complexity metrics, surfaces structural risk signals, and auto-generates human-readable reports.

Python API

from haoline import ModelInspector

inspector = ModelInspector()
report = inspector.inspect("model.onnx")

# Get metrics
print(f"Parameters: {report.params.total:,}")
print(f"FLOPs: {report.flops.total:,}")
print(f"Peak Memory: {report.memory.peak_activation_bytes / 1e9:.2f} GB")

# Export
report.to_json("report.json")
report.to_markdown("model_card.md")
report.to_html("report.html")

LLM Setup (Optional)

HaoLine can generate AI-powered summaries of your model architectures. Install with LLM support and set the API key for your preferred provider:

pip install haoline[llm]

Provider	Environment Variable	Get API Key
OpenAI	OPENAI_API_KEY	platform.openai.com
Anthropic	ANTHROPIC_API_KEY	console.anthropic.com
Google Gemini	GOOGLE_API_KEY	aistudio.google.com
xAI Grok	XAI_API_KEY	console.x.ai

# Set your preferred provider's API key
export OPENAI_API_KEY="sk-..."           # OpenAI
export ANTHROPIC_API_KEY="sk-ant-..."    # Anthropic
export GOOGLE_API_KEY="..."              # Google Gemini
export XAI_API_KEY="xai-..."             # xAI Grok

# Windows PowerShell
$env:OPENAI_API_KEY="sk-..."

# Use in analysis (auto-detects available provider)
haoline model.onnx --llm-summary

Security Notice

⚠️ Loading untrusted models is inherently risky.

Like PyTorch's torch.load(), HaoLine uses pickle and numpy.load(allow_pickle=True) when loading JAX model parameters. These can execute arbitrary code if the model file is malicious.

Best practices:

• Only analyze models from trusted sources
• Run in a sandboxed environment (Docker, VM) when analyzing unknown models
• Review model provenance before loading

Etymology

HaoLine (好线) combines:

• 好 (hǎo) = "good" in Chinese
• A personal touch from the author

"The good path through your neural network."
