ONNXMLTools enables you to convert models from different machine learning toolkits into ONNX. Currently the following toolkits are supported:
- Apple CoreML
- scikit-learn (subset of models convertible to ONNX)
Clone this repository on your local machine.
Currently you can install ONNXMLTools from source:
pip install git+https://github.com/onnx/onnxmltools
This package uses NumPy as well as ProtoBuf. Also If you are converting a model from Scikit-learn or Apple CoreML you need the following packages installed respectively:
- scikit-learn
- CoreMLTools
Here is a simple example to convert a CoreML model:
import onnxmltools
import coremltools
model_coreml = coremltools.utils.load_spec("image_recognition.mlmodel")
model_onnx = onnxmltools.convert.convert_coreml(model_coreml, "Image_Reco")
# Save as text
onnxmltools.utils.save_text(model_onnx, "image_recognition.json")
# Save as protobuf
onnxmltools.utils.save_model(model_onnx, "image_recognition.onnx")
