normalize_axis_tuple(axis, ndim, argname=None, allow_duplicate=False)
This handles shorthands such as 1
and converts them to (1,)
, as well as performing the handling of negative indices covered by normalize_axis_index
.
By default, this forbids axes from being specified multiple times.
Used internally by multi-axis-checking logic.
The un-normalized index or indices of the axis.
The number of dimensions of the array that :None:None:`axis` should be normalized against.
A prefix to put before the error message, typically the name of the argument.
If False, the default, disallow an axis from being specified twice.
If any axis provided is out of range
If an axis is repeated
The normalized axis index, such that :None:None:`0 <= normalized_axis < ndim`
Normalizes an axis argument into a tuple of non-negative integer axes.
normalize_axis_index
normalizing a single scalar axis
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
