The problem is that by putting from sage.parallel.all import parallel
in sage/rings/polynomial/multi_polynomial_ideal.py you changed the import order of the sage library causing the import to fail because now you try to import QuotientRing from the not yet completely initialized quotient_ring. This happens because there is a cyclic import (you see quotient_ring occuring twice in the traceback). -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
