Installation and Usage of the Paddle2ONNX Plugin¶

The Paddle2ONNX plugin for PaddleX provides the ability to convert PaddlePaddle static models to ONNX format models, leveraging the underlying Paddle2ONNX.

1. Installation¶

paddlex --install paddle2onnx

2. Usage¶

2.1 Parameter Introduction¶

Parameter	Type	Description
paddle_model_dir	str	Directory containing the Paddle model.
onnx_model_dir	str	Output directory for the ONNX model, which can be the same as the Paddle model directory. Defaults to `onnx`.
opset_version	int	The ONNX opset version to use. Defaults to `7`.

2.2 Usage Method¶

Usage:

paddlex \
    --paddle2onnx \  # Use the paddle2onnx function
    --paddle_model_dir /your/paddle_model/dir \  # Specify the directory where the Paddle model is located
    --onnx_model_dir /your/onnx_model/output/dir \  # Specify the output directory for the converted ONNX model
    --opset_version 7  # Specify the ONNX opset version to use

Taking the ResNet18 model from the image_classification module as an example:

paddlex \
    --paddle2onnx \
    --paddle_model_dir ./ResNet18 \
    --onnx_model_dir ./ResNet18 \
