Exporting an ONNX Model from Caffe2
Caffe2 supports exporting models directly to ONNX. Here are the steps:
Install Caffe2 by following the instructions provided in the official Caffe2 documentation.
Import the necessary libraries in your Python script:
1
2from caffe2.python.onnx import backend as caffe2_backend
import torch.onnxLoad your Caffe2 model into PyTorch:
1
2# Assuming you already have a Caffe2 model loaded
torch_model = torch.onnx.load("path/to/caffe2_model.pb")Export the PyTorch model to ONNX:
1
torch.onnx.export(torch_model, torch.randn(1, 3, 224, 224), "path/to/exported_model.onnx", verbose=True)
Adjust the input shape and replace “path/to/exported_model.onnx” with the desired path to save the ONNX file.
