from_delayed(value, shape, dtype=None, meta=None, name=None)
This routine is useful for constructing dask arrays in an ad-hoc fashion using dask delayed, particularly when combined with stack and concatenate.
The dask array will consist of a single chunk.
Create a dask array from a dask delayed value
>>> import daskThis example is valid syntax, but we were not able to check execution
... import dask.array as da
... import numpy as np
... value = dask.delayed(np.ones)(5)
... array = da.from_delayed(value, (5,), dtype=float)
... array dask.array<from-value, shape=(5,), dtype=float64, chunksize=(5,), chunktype=numpy.ndarray>
>>> array.compute() array([1., 1., 1., 1., 1.])See :

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
