jet.bindings.PathInfo¶

class PathInfo¶

Bases: pybind11_builtins.pybind11_object

PathInfo represents a contraction path in a tensor network.

Parameters

tn (TensorNetwork) – Tensor network associated with the contraction path.
path (List[Tuple[int, int]]) – Pairs of integers representing a contraction path through the tensor network.

Attributes

`index_to_size_map`	Mapping from indices to their dimension.
`num_leaves`	Number of leaf steps in this path
`path`	List of node ID pairs representing the contraction path.
`steps`	Steps of this path.

`total_flops`(self)	Computes the total number of floating-point operations needed to contract the tensor network along this path
`total_memory`(self)	Computes the total memory required to contract the tensor network along this path.

total_flops(self: jet.bindings.PathInfo) → float¶

Computes the total number of floating-point operations needed to contract the tensor network along this path

total_memory(self: jet.bindings.PathInfo) → float¶

Computes the total memory required to contract the tensor network along this path.
