BoundsError

When running PEPSKit.jl, an bound error occurs here

nested task error: BoundsError: attempt to access 15-element Vector{Tuple{Vector{ComplexF64}, Vector{ComplexF64}, Vector{ComplexF64}}} at index [16]

Does Ws here always have length of n? If I change for i in 1:n to for i in 1:length(Ws), is there any consequence?

Probably a duplicate of #110

Yes, it is a duplicate one. It occurs quite often with iterscheme=:fixed, not for iterscheme=:diffgauge. Does the later (iterscheme=:diffgauge) implement the linsolve for AD?
With the default settings of PEPSKit, the test for tf_ising.jl passes, but failed when I renormalize the tensors before ctmrg svd for projectors. I am confused as I think the normalization improves the stability.
