I have updated ITensor to the 3.1.2 version and the TDVP code my mingruyang now doesn't work anymore. It fails with a "LocalOp is null" error. Anyone can help?
I have also filled an issue on the TDVP page.
Thanks for catching this. I know the change to ITensor which is causing this bug, but didn't expect that the change would break the TDVP code. Could you please provide a minimal example to reproduce? Then I'll be better able to identify and fix the case which is breaking - thanks.
