_nan_mask(a, out=None)

Parameters

a : array-like

Input array with at least 1 dimension.

out : ndarray, optional

Alternate output array in which to place the result. The default is None ; if provided, it must have the same shape as the expected output and will prevent the allocation of a new array.

Returns

y : bool ndarray or True

A bool array where np.nan positions are marked with False and other positions are marked with True . If the type of a is such that it can't possibly contain np.nan , returns True .

Examples

See :

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
