Thank you for your reply and clarification.  
Coming back to this discussion [Ground state wavefunction](https://itensor.discourse.group/t/ground-state-wavefunction/1470)  
I wanted to use tensor cross interpolation to obtain to obtain the ground state wavefunction for systems with large number of sites (L\>100). So I am looking for ways to do this. Is there a package in Julia or Python that does it or is it necessary to write my own code for it?
