NodeDef.Builder

 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".

 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.
 

 This stores debug information associated with the node.

 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_>./]*".
 

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

 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.
