Hello,
I have been tweaking around with ITensors.jl package (GitHub - ITensor/ITensors.jl: A Julia library for efficient tensor computations and tensor network calculations) to create custom SitesTypes. I have tried the following and I am stuck with TagType (though this is included in the ITensors.jl file):
julia> using ITensors
julia> const SpinHalfSite = Union{TagType"S=1/2", TagType"SpinHalf"}
ERROR: LoadError: UndefVarError: @TagType_str not defined
in expression starting at REPL[2]:1
julia> import ITensors: TagType
julia> const SpinHalfSite = Union{TagType"S=1/2", TagType"SpinHalf"}
ERROR: LoadError: UndefVarError: @TagType_str not defined
in expression starting at REPL[4]:1
Though creating a new sitetype.jl file and including it in ITensors.jl works fine, is there a way to actually create new SiteTypes on the fly without tweaking the source?
Thanks!
PS: I am aware that the package in context is not production ready and in the preview stages, but any insight on the above issue would be great. Also, I did not want to open an issue as this seemed to be more like a trivial issue. Finally, it would be great to know if there are some pointers on which one can contribute to the above package (for this I have scanned through the Issues on github but did not find any good for beginners tags, so any insight on this would also be helpful).
