This object contains state to deterministically generate pseudo-random numbers from a variety of probability distributions. It is identical to np.random.RandomState except that all functions also take a chunks= keyword argument.

Parameters

seed: Number :

Object to pass to RandomState to serve as deterministic seed

RandomState: Callable[seed] -> RandomState :

A callable that, when provided with a seed keyword provides an object that operates identically to np.random.RandomState (the default). This might also be a function that returns a randomgen.RandomState , mkl_random , or cupy.random.RandomState object.

Mersenne Twister pseudo-random number generator

Examples

This example is valid syntax, but we were not able to check execution

>>> import dask.array as da
... state = da.random.RandomState(1234)  # a seed
... x = state.normal(10, 0.1, size=3, chunks=(2,))
... x.compute()
array([10.01867852, 10.04812289,  9.89649746])

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
