Can DL4J export an ONNX format model?

I want to export the ONNX format model from MultiLayerNetwork, but only

multiLayerNetwork.save(new File("model.zip"));

support, and it can only export a zip file, not ONNX. I trained the model and want to use in another application.

@Glowberry we only support onnx import unfortunately.

And is there any way to export in any other popular format, like CoreML etc.?

@b005t3r we never exported to any other format only import. People don’t usually train models in java. They might finetune but there just wasn’t enough commercial interest in that feature. As usual it’s just one of those tragedy of the commons. Dl4j’s always been more niche with a focus on inference.
Having the ability to train models is great and will always be supported/optimized for but format coverage let alone export would have to be sponsored development.

“Free” work will only go towards things with majority community interest not yet another format xyz.

If I did any work with coreml etc it would ONLY be for import. Otherwise you can just convert to onnx and try import like that.
