Exporting an ONNX Model from PyTorch

PyTorch provides a straightforward way to export models to the ONNX format. Follow these steps:

1. Ensure that you have PyTorch installed. You can install it using pip:

   pip install torch

2. Import the necessary libraries in your Python script:

   import torch
   import torchvision

3. Load your PyTorch model:

   model = torchvision.models.resnet18(pretrained=True)

4. Export the model to ONNX:

   torch.onnx.export(model, torch.randn(1, 3, 224, 224), "path/to/exported_model.onnx", export_params=True)

   Make sure to replace “path/to/exported_model.onnx” with the desired path to save the ONNX file.
