Best I can tell, no code in ITensorMakie.jl depends on ITensorMPS. So we can mark that one completed.

mtfishman commented 4 months ago

This is nearly complete, ITensorAFQMC.jl is private and not very functional anyway so isn't urgent to update, ITensorMPOCompression.jl has a pending PR, and PastaQ.jl has a pending PR which is hitting some issues that is very likely not directly caused by ITensorMPS.jl.

@emstoudenmire what's the status of ITensorQTT.jl? Can we take a minimal path to upgrading it to using ITensorMPS.jl now that #7 is complete? I think we shouldn't do anything ambitious there, at least not right now for the sake of completing this issue.

Good reminder. Now that ITensorMPS is updated, ITensorQTT can access all the types and methods it needs again, so tests are passing and I just made an ITensorQTT PR here: https://github.com/mtfishman/ITensorQTT.jl/pull/11

The biggest change is that I deleted ITensorQTT.linsolve since it's essentially the same as ITensorTDVP's linsolve (since it has the same signature it was causing a warning, otherwise I might have just left it alone).

Ok this is implemented as much as possible right now so I'll close.
