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?

Inizia da TensorFunction.java e Signature.java di TensorFlow Java, quindi confronta la loro gestione di TensorInfo con coo_sparse oneof in meta_graph.proto. Riproduci il caricamento del SavedModelBundle descritto e determina se è necessario modificare la validazione o il caricamento del modello; il lavoro è considerato completato quando il comportamento supportato è stato stabilito e coperto da un controllo di regressione appropriato oppure documentato come non supportato.
