Edge AI Platform

A comprehensive Edge AI platform with LLM (Ollama) and ML (ONNX Runtime) serving capabilities, monitoring, model conversion, and benchmarking tools.

🛠️ Model Conversion & Validation Tools

This project includes a powerful command-line interface (CLI) for converting and validating machine learning models, with a focus on ONNX format.

Installation

# Install the package in development mode
pip install -e .

# Install with TensorFlow support (for Keras/SavedModel conversion)
pip install -e .[tensorflow]

# Install with PyTorch support
pip install -e .[torch]

# Install with all dependencies
pip install -e .[all]

CLI Usage

Model Benchmarking

Benchmark ONNX models for performance metrics:

# Benchmark a single model
wronai_edge benchmark path/to/model.onnx --input-shape 1,3,224,224

# Compare multiple models
wronai_edge benchmark model1.onnx model2.onnx --compare --input-shape 1,3,224,224

# Customize benchmark parameters
wronai_edge benchmark model.onnx --warmup 20 --runs 200 --cpu

Options:

  • --input-shape, -i: Input shape (can be specified multiple times for multiple inputs)
  • --warmup: Number of warmup runs (default: 10)
  • --runs: Number of benchmark runs (default: 100)
  • --cpu/--gpu: Force CPU or GPU usage (default: GPU if available)
  • --compare: Compare multiple models side by side

Model Validation

Validate an ONNX model:

wronai_edge test-model path/to/model.onnx

Options:

  • --output-json: Save validation results to a JSON file
  • --verbose, -v: Enable verbose output

Example:

wronai_edge test-model models/simple-model.onnx --output-json validation_results.json --verbose

Model Conversion

Convert models between different formats using the convert command group.

PyTorch to ONNX:

wronai_edge convert pytorch model.pt output.onnx --input-shape 1,3,224,224

Keras to ONNX:

wronai_edge convert keras model.h5 output.onnx --input-shape 1,224,224,3

TensorFlow SavedModel to ONNX:

wronai_edge convert saved-model saved_model_dir output.onnx

Common options for conversion:

  • --opset: ONNX opset version (default: 13)
  • --verbose, -v: Enable verbose output

Python API

You can also use the conversion and validation tools programmatically:

from wronai_edge import validate_model, convert_to_onnx

# Validate a model
results = validate_model("model.onnx")
print(f"Model validation passed: {results['validation_summary']['passed']}")

# Convert a PyTorch model to ONNX
convert_to_onnx(
    model_path="model.pt",
    output_path="output.onnx",
    input_shapes=[(1, 3, 224, 224)],
    opset_version=13
)

For more examples, see the examples directory.

📚 Documentation

🚀 Quick Start

Prerequisites

  • Docker and Docker Compose
  • Python 3.8+ (for running tests and examples)
  • At least 8GB RAM (16GB recommended for running LLMs)
  • curl and jq (for testing and examples)

Starting the Platform

  1. Clone the repository:

    git clone https://github.com/wronai/edge.git
    cd edge
  2. Start all services:

    docker-compose up -d
  3. Verify services are running:

    docker-compose ps

    All services should show as "healthy" or "running".

  4. Run the test suite to verify everything is working:

    ./test_services.sh

Accessing Services

ONNX Runtime Management

# Check ONNX Runtime status
make onnx-status

# List available ONNX models
make onnx-models

# Load a new model
make onnx-load MODEL=simple-model MODEL_SOURCE=./models/simple-model.onnx

# Test inference with a sample request
make onnx-test

For detailed ONNX Runtime documentation, see docs/onnx-runtime.md

Example: Using ONNX Runtime

Here's how to use the ONNX Runtime service for model inference:

  1. Check service health:

    curl http://localhost:8001/health
    # Expected response: {"status": "OK"}
  2. List available models:

    curl http://localhost:8001/v1/models
    # Example response: {"models": ["model1.onnx", "model2.onnx"]}
  3. Run inference (using Python):

    import requests
    import numpy as np
    
    # Sample input data (adjust based on your model's expected input)
    input_data = {
        "model_name": "wronai.onnx",
        "input": {
            "input_1": np.random.rand(1, 224, 224, 3).tolist()  # Example for image input
        }
    }
    
    # Send inference request
    response = requests.post(
        "http://localhost:8001/v1/models/your_model:predict",
        json=input_data
    )
    
    # Process the response
    if response.status_code == 200:
        predictions = response.json()
        print("Inference successful!")
        print(f"Predictions: {predictions}")
    else:
        print(f"Error: {response.status_code}")
        print(response.text)
  4. Using cURL for simple inference:

    curl -X POST http://localhost:8001/v1/models/your_model:predict \
         -H "Content-Type: application/json" \
         -d '{"input": [[[0.1, 0.2, 0.3], [0.4, 0.5, 0.6]]]}'

For more advanced usage, refer to the API Reference.

Stopping the Platform

To stop all services:

docker-compose down

To remove all data (including models and metrics):

docker-compose down -v

🧪 Testing

Running Tests

We provide test scripts to verify all services are functioning correctly:

  1. Basic Service Tests - Verifies all core services are running and accessible:

    # Run all tests
    make test
    
    # Or run individual tests
    ./test_services.sh
  2. ONNX Runtime Tests - Test ONNX Runtime functionality:

    # Check ONNX Runtime status
    make onnx-status
    
    # Test with a sample request
    make onnx-test
  3. ONNX Model Test - Validates ONNX model loading and inference (requires Python dependencies):

    python3 -m pip install -r requirements-test.txt
    python3 test_onnx_model.py
  4. API Endpoint Tests - Comprehensive API tests (requires Python dependencies):

    python3 test_endpoints.py

Expected Test Results

When all services are running correctly, you should see output similar to:

=== Testing Direct Endpoints ===
Testing Ollama API (http://localhost:11435/api/tags)... PASS (Status: 200)
Testing ONNX Runtime (http://localhost:8001/v1/)... PASS (Status: 405)

=== Testing Through Nginx Gateway ===
Testing Nginx -> Ollama (http://localhost:30080/api/tags)... PASS (Status: 200)
Testing Nginx -> ONNX Runtime (http://localhost:30080/v1/)... PASS (Status: 405)
Testing Nginx Health Check (http://localhost:30080/health)... PASS (Status: 200)

=== Testing Monitoring ===
Testing Prometheus (http://localhost:9090)... PASS (Status: 302)
Testing Prometheus Graph (http://localhost:9090/graph)... PASS (Status: 200)
Testing Grafana (http://localhost:3007)... PASS (Status: 302)
Testing Grafana Login (http://localhost:3007/login)... PASS (Status: 200)

Note: A 405 status for ONNX Runtime is expected for GET requests to /v1/ as it requires POST requests for inference. The 302 status codes for Prometheus and Grafana are expected redirects to their respective UIs.

Model Inference

# Make a prediction using the default model (complex-cnn-model)
make onnx-predict

# Or use curl directly
curl -X POST http://localhost:8001/v1/models/complex-cnn-model/versions/1:predict \
  -H "Content-Type: application/json" \
  -d '{"instances": [{"data": [1.0, 2.0, 3.0, 4.0]}]}'

# Example with Python
python3 -c "
import requests
import json

response = requests.post(
    'http://localhost:8001/v1/models/complex-cnn-model/versions/1:predict',
    json={"instances": [{"data": [1.0, 2.0, 3.0, 4.0]}]}
)
print(json.dumps(response.json(), indent=2))
"

Benchmarking

# Run a benchmark with 100 requests
make onnx-benchmark

# Customize model and version
make onnx-benchmark MODEL_NAME=my-model MODEL_VERSION=2

Notes:

  • The server automatically loads models from the /models directory in the container
  • To use a different model:
    1. Place your .onnx model file in the ./models directory
    2. Update the model name/version in your requests or set environment variables:
      export MODEL_NAME=your-model
      export MODEL_VERSION=1
    3. Or specify them when running commands:
      make onnx-predict MODEL_NAME=your-model MODEL_VERSION=1

Test Ollama LLM

# Simple chat
curl -X POST http://localhost:30080/api/generate \
  -H "Content-Type: application/json" \
  -d '{
    "model": "llama3.2:1b",
    "prompt": "Explain edge computing",
    "stream": false
  }'

# Custom edge AI assistant
curl -X POST http://localhost:30080/api/generate \
  -H "Content-Type: application/json" \

Troubleshooting

Common Issues and Solutions

1. Disk Space Issues If the deployment fails with eviction errors or the cluster won't start:

# Check disk space
df -h

# Clean up Docker system
docker system prune -a -f --volumes

# Remove unused containers, networks, and images
docker container prune -f
docker image prune -a -f
docker network prune -f
docker volume prune -f

# Clean up old logs and temporary files
sudo journalctl --vacuum-time=3d
sudo find /var/log -type f -name "*.gz" -delete
sudo find /var/log -type f -name "*.1" -delete

2. Debugging K3s Cluster

# Check K3s server logs
docker logs k3s-server

# Check cluster status
docker exec k3s-server kubectl get nodes
docker exec k3s-server kubectl get pods -A

3. Port Conflicts If you see port binding errors, check and free up required ports (80, 443, 6443, 30030, 30090, 30080):

# Check port usage
sudo lsof -i :8080  # Replace with your port number

4. Debugging Pods

# Debug pod issues
kubectl describe pod <pod-name> -n ai-inference

# Check resource usage
kubectl top pods -n ai-inference --sort-by=memory

# View events
kubectl get events -n ai-inference --sort-by='.lastTimestamp'

# Restart services
kubectl rollout restart deployment/ollama-llm -n ai-inference

5. Reset Everything If you need to start fresh:

# Clean up all resources
./scripts/deploy.sh cleanup

# Remove all Docker resources
docker system prune -a --volumes --force

# Remove K3s data
sudo rm -rf terraform/kubeconfig/*
sudo rm -rf terraform/k3s-data/*
sudo rm -rf terraform/registry-data/*

Cleanup

# Complete cleanup
./scripts/deploy.sh cleanup

# Partial cleanup (keep infrastructure)
kubectl delete -f k8s/monitoring.yaml
kubectl delete -f k8s/ai-platform.yaml
