Research direction
Start with TensorFlow Java's TensorFunction.java and Signature.java, then compare their TensorInfo handling with the coo_sparse oneof in meta_graph.proto. Reproduce loading the described SavedModelBundle and determine whether validation or model loading must change; done means the supported behavior is established and covered by an appropriate regression check or documented as unsupported.
Written by the indexing model from the issue text.
Description
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?
