2 years ago Hi,
thank you very much for pointing this out. This script was first used to benchmark against another eliashberg implementation but has long been deprecated, so I think it's best to just remove it, see attached PR.
If you want to see other examples of the eliashberg implementation checkout the following links:

While executing the Eliashberg code in the benchmark folder of the package, I am getting the following error :
