Struct tfrecord::protos::OpDef [−][src]
Defines an operation. A NodeDef in a GraphDef specifies an Op by using the “op” field which should match the name of a OpDef. LINT.IfChange
Fields
name: String
Op names starting with an underscore are reserved for internal use. Names should be CamelCase and match the regexp “[A-Z][a-zA-Z0-9>_]*”.
input_arg: Vec<ArgDef>
Description of the input(s).
output_arg: Vec<ArgDef>
Description of the output(s).
control_output: Vec<String>
Named control outputs for this operation. Useful only for composite operations (i.e. functions) which want to name different control outputs.
attr: Vec<AttrDef>
deprecation: Option<OpDeprecation>
Optional deprecation based on GraphDef versions.
summary: String
One-line human-readable description of what the Op does.
description: String
Additional, longer human-readable description of what the Op does.
is_commutative: bool
True if the operation is commutative (“op(a,b) == op(b,a)” for all inputs)
is_aggregate: bool
If is_aggregate is true, then this operation accepts N >= 2 inputs and produces 1 output all of the same type. Should be associative and commutative, and produce output with the same shape as the input. The optimizer may replace an aggregate op taking input from multiple devices with a tree of aggregate ops that aggregate locally within each device (and possibly within groups of nearby devices) before communicating. TODO(josh11b): Implement that optimization.
for things like add
is_stateful: bool
Ops are marked as stateful if their behavior depends on some state beyond their input tensors (e.g. variable reading op) or if they have a side-effect (e.g. printing or asserting ops). Equivalently, stateless ops must always produce the same output for the same input and have no side-effects.
By default Ops may be moved between devices. Stateful ops should either not be moved, or should only be moved if that state can also be moved (e.g. via some sort of save / restore). Stateful ops are guaranteed to never be optimized away by Common Subexpression Elimination (CSE).
for things like variables, queue
allows_uninitialized_input: bool
By default, all inputs to an Op must be initialized Tensors. Ops that may initialize tensors for the first time should set this field to true, to allow the Op to take an uninitialized Tensor as input.
for Assign, etc.
