RandomNumbers

Draw an array of random numbers from a passed-in distribution, optionally matching a template array in shape and optionally data type.

A random seed must be passed in, see also CreateRandomSeed for documentation on how seeds are best managed. The node supports alternative compute backends, which can be used to force the result onto a specific backend (while the actual sampling is provided by the distribution's backend, which may or may not be the same). Version 0.8.0

Ports/Properties

dist

Distribution to use.

verbose name
Dist
default value
None
port type
DataPort
value type
Distribution (can be None)
data direction
IN

like

Optional template array.

verbose name
Like
default value
None

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

data

Output data.

verbose name
Data
default value
None
port type
DataPort
value type
AnyNumeric (can be None)
data direction
OUT

shape

Shape of the array. Can be set to None if a template array is provided via the like input.

verbose name
Shape
default value
[]
port type
ListPort
value type
list (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 as the like= argument, otherwise the compute backend of the distribution. 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 the precision that the distribution is configured with.

verbose name
Precision
default value
keep
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)
