No valid Treelite model files found under folder (XGBOOST)

[rymoore]

I've created a Sagemaker XGBOOST model and compiled it for NEO using:

compiled_model = xgb.compile_model(target_instance_family='rasp3b', 
                                   role=role,
                                   framework='xgboost',
                                   framework_version='0.7',
                                   output_path=output_path)

I am deploying this model to a RPI3 via Greengrass for inference using dlr. When I use the following Python code on the device:

model = DLRModel('model', input_shape, output_shape, device)

I get an error "No valid Treelite model files found under folder". My "model" directory has a single file called "compiled_model.so".

What steps am I missing?

@rymoore Which version of DLR did you use, and how did you install it?
