Abstract representation of shape. Shapes are
Viewable. This base class handles transforming landmarks when the shape is transformed. Therefore, implementations of
Shapehave to implement the abstract

Returns a flattened representation of the object as a single vector.
vector ((N,) ndarray) – The core representation of the object, flattened into a single vector. Note that this is always a view back on to the original object, but is not writable.
Generate an efficient copy of this object.
Note that Numpy arrays and other
selfwill be deeply copied. Dictionaries and sets will be shallow copied, and everything else will be assigned (no copy will be made).
Classes that store state other than numpy arrays and immutable types should overwrite this method to ensure all state is copied.
type(self)– A copy of this object
Build a new instance of the object from it’s vectorized state.
selfis used to fill out the missing state required to rebuild a full object from it’s standardized flattened state. This is the default implementation, which is which is a
deepcopyof the object followed by a call to
from_vector_inplace(). This method can be overridden for a performance benefit if desired.
(n_parameters,)ndarray) – Flattened representation of the object.
type(self)) – An new instance of this class.
Deprecated. Use the non-mutating API,

Tests if the vectorized form of the object contains
nanvalues or not. This is particularly useful for objects with unknown values that have been mapped to
has_nan_values (bool) – If the vectorized object contains
The total number of dimensions.
Whether the object has landmarks.
The number of landmark groups on this object.
The length of the vector that this object produces.
