Struct tract_tensorflow::tfpb::tensorflow::NodeDef

pub struct NodeDef {
    pub name: String,
    pub op: String,
    pub input: Vec<String>,
    pub device: String,
    pub attr: HashMap<String, AttrValue>,
}

Fields

name: String

The name given to this operator. Used for naming inputs, logging, visualization, etc. Unique within a single GraphDef. Must match the regexp “[A-Za-z0-9.][A-Za-z0-9_./]*”.

op: String

The operation name. There may be custom parameters in attrs. Op names starting with an underscore are reserved for internal use.

input: Vec<String>

Each input is “node:src_output” with “node” being a string name and “src_output” indicating which output tensor to use from “node”. If “src_output” is 0 the “:0” suffix can be omitted. Regular inputs may optionally be followed by control inputs that have the format “^node”.

device: String

A (possibly partial) specification for the device on which this node should be placed. The expected syntax for this string is as follows:

DEVICE_SPEC ::= PARTIAL_SPEC

PARTIAL_SPEC ::= (“/” CONSTRAINT) * CONSTRAINT ::= (“job:” JOB_NAME) | (“replica:” [1-9][0-9]) | (“task:” [1-9][0-9]) | (“device:” [A-Za-z]* “:” ([1-9][0-9]* | “*”) )

Valid values for this string include:

• “/job:worker/replica:0/task:1/device:GPU:3” (full specification)
• “/job:worker/device:GPU:3” (partial specification)
• “” (no specification)

If the constraints do not resolve to a single device (or if this field is empty or not present), the runtime will attempt to choose a device automatically.

attr: HashMap<String, AttrValue>

Operation-specific graph-construction-time configuration. Note that this should include all attrs defined in the corresponding OpDef, including those with a value matching the default – this allows the default to change and makes NodeDefs easier to interpret on their own. However, if an attr with a default is not specified in this list, the default will be used. The “names” (keys) must match the regexp “[a-z][a-z0-9_]+” (and one of the names from the corresponding OpDef’s attr field). The values must have a type matching the corresponding OpDef attr’s type field. TODO(josh11b): Add some examples here showing best practices.
