SavedModelBundle Unable to Load Models with coo_sparse Encoded Input

Was trying to load a model using SavedModelBundle.load(savedModelPath, "serve") but ran into the operand "" does not exist on the graph issue. Error log:

Looking into Tensorflow Java source code this error is raised here.

And by inspecting the model being loaded the corresponding input tensor is coo_sparse encoded:

It appears to me that when building TensorDescription the library doesn't take coo_sparse encoded format into account: code link: it's trying to fetch the name field which is always empty for coo_sparse encoded format, because together with the name field it's oneof in TensorInfo proto: code link.

Is this a known unsupported feature or would the model loading just work if the validation is bypassed?

Comience con TensorFunction.java y Signature.java de TensorFlow Java y, a continuación, compare su gestión de TensorInfo con coo_sparse oneof en meta_graph.proto. Reproduzca la carga del SavedModelBundle descrito y determine si es necesario cambiar la validación o la carga del modelo; se considera terminado cuando el comportamiento compatible esté establecido y cubierto por una comprobación de regresión adecuada o documentado como no compatible.
