五、Summary and Reference 一、简介 工作中一直会用到ONNX,抽时间对ONNX做了一些总结。 ONNX是Open Neural Network Exchange的简称,创始人是贾扬清,从2017年由微软、facebook等几个公司联合推出,它定义了一个统一的中间格式,用以存储训练好的模型,这就使得不同的训练框架可以使用相同的中间格式进行交互,下图直观...
使用torch.onnx.export函数将PyTorch模型转换为ONNX格式。这包括指定模型(model)、输入数据(img)、输出文件名(f)、操作集版本(opset_version=12)、输入输出名、以及(可选的)动态轴配置。动态轴允许模型在不同的批次大小和图像长宽下运行 onnx_model ,加载导出的ONNX模型文件,以便进行进一步的检查 使用ONNX的检查...
# 也可以命令行输入python3 -m onnxsim input_onnx_model output_onnx_model # 或者使用在线网站直接转换https://convertmodel.com/ # 输出模型名 filename = output_name + "sim.onnx" # 简化模型 # 设置skip_fuse_bn=True表示跳过融合bn层,pytorch高版本融合bn层会出错 simplified_model, check = simpl...

ONNX is an open-source format designed for machine learning models. It ensures cross-platform compatibility. This format also supports major languages and frameworks, facilitating efficient model exchange.
In summary, ONNX Script offers a new Python-first programming model for authoring ONNX models that integrates with the existing rich ecosystem of Python tooling and environments. Going forward, we envision ONNX Script as a means for defining and extending ONNX itself. New core opera...
assert check, "Simplified ONNX model could not be validated" use model_simp as a standard ONNX model object 我们在导出ONNX模型的一般流程就是,去掉后处理(如果预处理中有部署设备不支持的算子,也要把预处理放在基于nn.Module搭建模型的代码之外),尽量不引入自定义OP,然后导出ONNX模型,并过一遍onnx-simpl...
