RandomIntegers

Draw an array of random integers from a uniform distribution with a given low and high value (the high value being exclusive), optionally matching a template array in shape and optionally data type.

If deterministic results are sought, pass in a seed; see also CreateRandomSeed for documentation on how seeds are best managed. The node supports alternative compute backends, which can be used to speed up processing. Version 0.8.0

Ports/Properties

array

Output array.

  • verbose name: Array
  • default value: None
  • port type: DataPort
  • value type: AnyArray (can be None)
  • data direction: OUT

like

Optional template array.

  • verbose name: Like
  • default value: None
  • port type: DataPort
  • value type: AnyArray (can be None)
  • data direction: IN

seed

Random seed for deterministic results.

  • verbose name: Seed
  • default value: None
  • port type: DataPort
  • value type: AnyArray (can be None)
  • data direction: IN

shape

Shape of the array. Can be omitted if a template array is provided.

  • verbose name: Shape
  • default value: []
  • port type: ListPort
  • value type: list (can be None)

low

Lower bound (inclusive).

  • verbose name: Low
  • default value: 0
  • port type: FloatPort
  • value type: float (can be None)

high

Upper bound (exclusive).

  • verbose name: High
  • default value: 10
  • port type: FloatPort
  • value type: float (can be None)

backend

Optional compute backend to use. Keep is the current default, which resolves to that of the template array if one is provided and otherwise numpy unless overridden. Numpy is the standard CPU backend that underpins most of NeuroPype's operations. The others require one or more GPUs to be present on the system, except for torch-cpu. For best performance, keep all arrays that interact with each other (via processing nodes) on the same backend.

  • verbose name: Backend
  • default value: keep
  • port type: EnumPort
  • value type: str (can be None)

precision

Numeric precision to use. Keep resolves to the precision of the template array if one is provided, and otherwise to the current default (usually 64-bit). Can be reduced to save memory (e.g. if running on GPU).

  • verbose name: Precision
  • default value: int32
  • port type: EnumPort
  • value type: str (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
