[ 1254s] The package obsoletes itself.  This is known to cause errors in
various tools
[ 1254s] and should thus be avoided, usually by using appropriately versioned
Obsoletes
[ 1254s] and/or Provides and avoiding unversioned ones.

Provides:       python3-%{name} = %{version}
Obsoletes:      python3-%{name}

should be

Provides:       python3-%{name} = %{version}
Obsoletes:      python3-%{name} < %{version}

in both case.
