The problem occurs when I try to plot a map of the voltage on the sample, to
check that everything is working. The problem does not seem to occur when
assigning it to a builder element
sys[lattice.shape(shape_sr, (1,1))] = onsite
gives no error messages.
This is what I am trying to do, I write a function that calculates the voltage
(I followed one of your tutorials)
def V(sys):
Hd = onsite(site)
return (Hd[0,0] - Hd[1,1]).real
and then
sys = sys.finalized()
kwant.plotter.map(sys, V)
to try to plot it, but then I get the error.

This shouldn’t be. Can you provide a complete script that
demostrates the problem?
