Expand description

A function can be instantiated when the runtime can bind every attr with a value. When a GraphDef has a call to a function, it must have binding for every attr defined in the signature.

TODO(zhifengc):

  • device spec, etc.

Fields

signature: Option<OpDef>

The definition of the function’s name, arguments, return values, attrs etc.

attr: HashMap<String, AttrValue>

Attributes specific to this function definition.

arg_attr: HashMap<u32, ArgAttrs>resource_arg_unique_id: HashMap<u32, u32>

Unique IDs for each resource argument, used to track aliasing resources. If Argument A and Argument B alias each other, then resource_arg_unique_ids[A.index] == resource_arg_unique_ids[B.index].

If this field is empty, none of the arguments could alias; otherwise, every resource argument should have an entry in this field.

When instantiated, the unique IDs will be attached to the _Arg nodes’ “_resource_arg_unique_id” attribute.

node_def: Vec<NodeDef>

By convention, “op” in node_def is resolved by consulting with a user-defined library first. If not resolved, “func” is assumed to be a builtin op.

ret: HashMap<String, String>

A mapping from the output arg names from signature to the outputs from node_def that should be returned by the function.

control_ret: HashMap<String, String>

A mapping from control output names from signature to node names in node_def which should be control outputs of this function.
