Having a trained DRFModel instance in scala, what's the best way of generating the corresponding MojoModel object for scoring? from the api s I've seen so far, mostly are around exporting to a file and then loading back up using the MojoModel.load(path) for instance but no direct conversion?
The model instance currently cannot be converted to mojo instance without going through MojoWriter.
MojoWriter provides method
abstract public void writeTo(OutputStream os);
You can use it to write the mojo to a byte array (using a ByteArrayOutputStream) and then use it as a source of the mojo data:
ByteArrayOutputStream os = new ByteArrayOutputStream();
model.getMojo().writeTo(os);
MojoModel mojoModel = MojoModel.load(MojoReaderBackendFactory.createReaderBackend(
new ByteArrayInputStream(os.toByteArray()), MojoReaderBackendFactory.CachingStrategy.MEMORY));
