Hi, Why does adding :
from sage.rings.polynomial.polynomial_ring_constructor import PolynomialRing at the beginning of quotient_ring_element.py create the weird error: Traceback (most recent call last): … AttributeError: 'module' object has no attribute 'quotient_ring' Is there a circular dependency problem? If so, how can I possibly create polynomial rings inside quotient_ring_element ???
