Model Conversion and Optimization

=== ONNX Model Export and Optimization ===

PyTorch to ONNX

import torch

import onnx

model = MyModel()

model.load_state_dict(torch.load("model.pth"))

model.eval()

dummy_input = torch.randn(1, 3, 224, 224)

torch.onnx.export(

model, dummy_input, "model.onnx",

input_names=["input"],

output_names=["output"],

dynamic_axes={"input": {0: "batch_size"}, "output": {0: "batch_size"}},

opset_version=17,

)

Optimize with ONNX Runtime

import onnxruntime as ort

from onnxruntime.transformers import optimizer

optimized = optimizer.optimize_model(

"model.onnx",

model_type="bert",

)

optimized.save_model_to_file("model_optimized.onnx")

Quantize INT8

from onnxruntime.quantization import quantize_dynamic, QuantType

quantize_dynamic(

"model_optimized.onnx",

"model_int8.onnx",

weight_type=QuantType.QInt8,

)

Python Inference

import onnxruntime as ort

import numpy as np

providers = ['CUDAExecutionProvider', 'CPUExecutionProvider']

session = ort.InferenceSession("model.onnx", providers=providers)

input_name = session.get_inputs()[0].name

result = session.run(None, {input_name: np.random.randn(1, 3, 224, 224).astype(np.float32)})

C++ Inference

#include <onnxruntime_cxx_api.h>

Ort::Env env(ORT_LOGGING_LEVEL_WARNING, "inference");

Ort::SessionOptions options;

options.SetGraphOptimizationLevel(GraphOptimizationLevel::ORT_ENABLE_ALL);

Ort::Session session(env, "model.onnx", options);

JavaScript (Web)

import * as ort from 'onnxruntime-web';

const session = await ort.InferenceSession.create('model.onnx',

{ executionProviders: ['webgpu', 'wasm'] });

const feeds = { input: new ort.Tensor('float32', inputData, [1, 3, 224, 224]) };

const results = await session.run(feeds);

Mobile (React Native)

import { InferenceSession } from 'onnxruntime-react-native';

เคล็ดลับ

Olive: ใช้ Olive Toolchain Optimize อัตโนมัติ ไม่ต้องทำมือ
INT8: เริ่มด้วย INT8 Quantization ได้ 3-4x speedup แทบไม่เสีย Accuracy
Dynamic: ใช้ Dynamic Axes สำหรับ Variable Batch Size
Provider: ทดสอบทุก Execution Provider เลือกที่เร็วสุดบน Hardware
Profile: ใช้ ONNX Runtime Profiler หาจุด Bottleneck
