The grace-tensorpotential Conda page claims the package is architecture independent, but if I try to conda-install on my machine (osx-arm64) I get a complaint that matscipy can't be found by conda. As far as I can tell, this complaint is completely legitimate as the conda page for matscipy indicates it is only for linux-64 and osx-64 architectures. Since no version of matscipy is pinned here, I scrolled back through their conda release files but it appears to be exclusively those two architectures the whole way through.
