Web28 jul. 2024 · ITensor is a system for programming tensor network calculations with an interface modeled on tensor diagram notation, which allows users to focus on the connectivity of a tensor network without manually bookkeeping tensor indices. The ITensor interface rules out common programming errors and enables rapid prototyping of tensor … Web5 feb. 2024 · With ITensor we don't have the notion of a transpose. Instead we have primed indices. So a tensor that has indices like T_ {i i'} is like a square matrix. Then to …

Webclass tensorrt.ITensor A tensor in an INetworkDefinition . Variables name – str The tensor name. For a network input, the name is assigned by the application. For tensors which are layer outputs, a default name is assigned consisting of the layer name followed by the index of the output in brackets. shape – Dims The shape of a tensor. Web13 apr. 2024 · I would be very interested in using ITensor as a lower level symmetric tensor manipulation library, and I'm looking into wrapping parts of it in a higher level language to use together with existing code (mainly iPEPS). The part that I would be most interested in is the translation from tensor to block-sparse matrix form and back.

Therefore it is not necessary to know the ordering of an ITensor's indices, only which indices an ITensor has. Operations like contraction and addition of ITensors automatically handle any memory permutations.
