Good evening, I am encountering an issue when trying to use this method: modelAssetWithSpecificationData:blobMapping:error: I provide the specification data and a blobMapping. In the generated spec I can see the weights are referenced with this way: @model_path/weights/weight.bin In model.mlmodel. I populate my blob mapping with the content of weights.bin with a URL that matches the above string. However, I don't believe the blobMapping is ever being accessed because I get the following error: Error: compiler error: Encountered an error while compiling a neural network model: in operation const_0_to_fp16: Cannot interpret @model_path when ModelPath is unset I can confirm that the operation is the first use of weights in the model.mlmodel I have not yet found a way to set ModelPath or to change that string. Any assistance would be greatly appreciated.
