初识 ONNX

ONNX 定义

ONNX is an open format built to represent machine learning models. ONNX defines a common set of operators - the building blocks of machine learning and deep learning models - and a common file format to enable AI developers to use models with a variety of frameworks, tools, runtimes, and compilers.

ONNX 是一种用于表征机器学习模型的开放格式构建。 ONNX 定义了一组通用算子——机器学习和深度学习模型的构建块——以及一种通用文件格式，使 AI 开发人员能够使用不同框架、工具、运行时和编译器类型下的模型。

ONNX 作用

ONNX Runtime

ONNX Runtime is a performance-focused engine for ONNX models, which inferences efficiently across multiple platforms and hardware (Windows, Linux, and Mac and on both CPUs and GPUs).

ONNX Python 安装

Linux下 pytorch 1.8的极简安装

conda create -n torch18 python= 3.7.6

conda  activate torch18 

pip3 install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio==0.8.1 -f https://download.pytorch.org/whl/lts/1.8/torch_lts.html

pip install numpy protobuf==3.16.0
pip install onnx

conda install --name torch18 ipykernel -y

这条命令非必须运行【盲猜】

sudo apt install vulkan-utils
