Open Neural Network Exchange (ONNX) is an open standard format for representing machine learning models. It allows models trained in one deep learning framework to be transferred and used in another. PyTorch, a popular deep learning framework, supports exporting models to ONNX format. However, it's essential to understand the compatibility between PyTorch and ONNX versions to ensure a smooth model export process.
In this tutorial, we will explore the compatibility between PyTorch and ONNX versions and provide code examples to demonstrate how to export a PyTorch model to ONNX format.
Before starting this tutorial, make sure you have the following installed:
PyTorch: Follow the official PyTorch installation guide at https://pytorch.org/get-started/locally/ to install PyTorch.
ONNX: Install the ONNX package using pip:
Refer to the official PyTorch and ONNX compatibility matrix to ensure that you are using compatible versions. The matrix can be found at https://onnx.ai/supported-tools.html. Choose the appropriate PyTorch and ONNX versions based on your model and framework requirements.
Let's go through the process of exporting a simple PyTorch model to ONNX format.

PyTorch is a popular deep learning framework that allows researchers and developers to build and train neural networks efficiently. The Open Neural Network Exchange (ONNX) format, on the other hand, is an open standard for representing machine learning models. In this tutorial, we will explore the compatibility between different versions of PyTorch and ONNX, and provide code examples to demonstrate the conversion process.
Before we begin, make sure you have the following installed:
It's essential to be aware of the compatibility matrix between PyTorch and ONNX versions. Different versions of PyTorch may have varying support for ONNX features. Refer to the official PyTorch documentation for the compatibility matrix.
Now, let's create a simple PyTorch model and convert it to ONNX format. We'll use a basic example of a feedforward neural network.
In this example, we define a simple neural network with one fully connected layer. We then create an instance of the model and generate dummy input data. Finally, we use the torch.onnx.export function to convert the PyTorch model to the ONNX format.
If you encounter compatibility issues during the conversion process, consider upgrading or downgrading your PyTorch and ONNX versions based on the compatibility matrix. You can install specific versions u
