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?

Commencez par TensorFunction.java et Signature.java de TensorFlow Java, puis comparez leur gestion de TensorInfo avec coo_sparse oneof dans meta_graph.proto. Reproduisez le chargement du SavedModelBundle décrit et déterminez si la validation ou le chargement du modèle doit être modifié ; le travail est considéré comme terminé lorsque le comportement pris en charge est établi et couvert par une vérification de régression appropriée, ou documenté comme non pris en charge.
