__init_subclass__()

__reduce__()

Helper for pickle.

__reduce_ex__(protocol, /)

Helper for pickle.

__repr__(self: _pyngraph.Dimension) → str
__setattr__(name, value, /)

Implement setattr(self, name, value).

__sizeof__()

Size of object in memory, in bytes.

__str__(self: _pyngraph.Dimension) → str
__subclasshook__()

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

compatible(self: _pyngraph.Dimension, d: _pyngraph.Dimension) → bool

Check whether this dimension is capable of being merged with the argument dimension.

Parameters

d (Dimension) – The dimension to compare this dimension with.

Returns

True if this dimension is compatible with d, else False.

Return type

bool

static dynamic() → _pyngraph.Dimension
get_length(self: _pyngraph.Dimension) → int

Return this dimension as integer. This dimension must be static and non-negative.

:return Value of the dimension. :rtype: int

get_max_length(self: _pyngraph.Dimension) → int

Return this dimension’s max_dimension as integer. This dimension must be dynamic and non-negative.

Returns

Value of the dimension.

Return type

int

get_min_length(self: _pyngraph.Dimension) → int

Return this dimension’s min_dimension as integer. This dimension must be dynamic and non-negative.

Returns

Value of the dimension.

Return type

int

property is_dynamic

Check if Dimension is dynamic.

Returns

True if dynamic, else False.

Return type

bool

property is_static

Check if Dimension is static.

Returns

True if static, else False.

Return type

bool

refines(self: _pyngraph.Dimension, d: _pyngraph.Dimension) → bool

Check whether this dimension is a refinement of the argument. This dimension refines (or is a refinement of) d if:

  1. this and d are static and equal

  2. d dimension contains this dimension

this.refines(d) is equivalent to d.relaxes(this).

Parameters

d (Dimension) – The dimension to compare this dimension with.

Returns

True if this dimension refines d, else False.

Return type

bool

relaxes(self: _pyngraph.Dimension, d: _pyngraph.Dimension) → bool

Check whether this dimension is a relaxation of the argument. This dimension relaxes (or is a relaxation of) d if:

  1. this and d are static and equal

  2. this dimension contains d dimension

this.relaxes(d) is equivalent to d.refines(this).

Parameters

d (Dimension) – The dimension to compare this dimension with.

Returns

True if this dimension relaxes d, else False.

Return type

bool

same_scheme(self: _pyngraph.Dimension, dim: _pyngraph.Dimension) → bool

Return this dimension’s max_dimension as integer. This dimension must be dynamic and non-negative.

Parameters

dim (Dimension) – The other dimension to compare this dimension to.

Returns

True if this dimension and dim are both dynamic,

or if they are both static and equal, otherwise False. :rtype: bool
