Graph Descriptor

Descriptor of an AnvlGraph. This is a mutable class.

Usage

GraphDescriptor(
  calls = list(),
  tensor_to_gval = NULL,
  gval_to_box = NULL,
  constants = list(),
  in_tree = NULL,
  out_tree = NULL,
  inputs = list(),
  outputs = list(),
  is_static_flat = NULL,
  static_args_flat = NULL,
  devices = character()
)

Arguments

calls

(list(PrimitiveCall))
The primitive calls that make up the graph.

tensor_to_gval

(hashtab)
Mapping: AnvlArray -> GraphValue

gval_to_box

(hashtab)
Mapping: GraphValue -> GraphBox

constants

(list(GraphValue))
The constants of the graph.

in_tree

(NULL | Node)
The tree of inputs. May contain leaves for both array inputs and static (non-array) arguments. Only the array leaves correspond to entries in inputs; use is_static_flat to distinguish them.

out_tree

(NULL | Node)
The tree of outputs.

inputs

(list(GraphValue))
The inputs to the graph (array arguments only).

outputs

(list(GraphValue))
The outputs of the graph.

is_static_flat

(NULL | logical())
Boolean mask indicating which flat positions in in_tree are static (non-array) args. NULL when all args are array inputs.

static_args_flat

(NULL | list())
Flattened traced values for the static arguments indicated by is_static_flat.

devices

(character())
Device platforms encountered during tracing (e.g. "cpu", "cuda"). Populated automatically as arrays are registered.
