You introduce a circular import when you add the import statement for physical constants to sage/symbolic/all.py. The first part of the traceback looks exactly like the one from #11116. I was just trying to clean up some of those dependencies. The patch attached to that ticket doesn't solve the problem there, but it might help you. http://trac.sagemath.org/sage_trac/attachment/ticket/11116/trac_11116-fix_imports.patch Cheers, Burcin -- 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
