r/MachineLearning - [P] Run inference with zero dependencies C code and ONNX

In short, onnx provides an Open Neural Network Exchange format. This format, describes a huge set of operators, that can be mixed to create every type of machine learning model that you ever heard of, from a simple neural network to complex deep convolutional networks. Some examples of operators are: matrix multiplications, convolutions, adding, maxpool, sin, cosine, you name it! They provide a standardised set of operators here. So we can say that onnx provides a layer of abstraction to ML models, which makes all framework compatible between them.
