We had a similar problem with gnuradio recently (see #1130527,
but the correct hint is in the hint file of Sebastian and not
mine in the bug).

The first question is why pytorch-sparse+pytorch-scatter were tried
together with pytorch on amd64 only.

The bigger issue is that for non-smooth transitions all (transitive)
rdeps in level > 2 must be tried together with the package(s) in
level 2 they depend on.

This now needs something like
  easy pytorch-sparse/arm64 pytorch-scatter/arm64
  easy pytorch-sparse/ppc64el pytorch-scatter/ppc64el
  easy pytorch-sparse/riscv64 pytorch-scatter/riscv64
  easy pytorch-sparse/s390x pytorch-scatter/s390x
and Britney should figure that out without manual hinting.

Migrating pytorch-scatter/arch making a package from pytorch-sparse/arch
uninstallable should be an automatic hint that adding pytorch-sparse/arch
to whatever was just tried might be worth a try.
