Hi there, This seemed to have been asked before (the solution to it didn't help very much), but I get the following error: sage: A = AbstractPolynomialRing(QQ); A --------------------------------------------------------------------------- NameError Traceback (most recent call last) <ipython-input-1-165834f76584> in <module>() ----> 1 A = AbstractPolynomialRing(QQ); A
NameError: name 'AbstractPolynomialRing' is not defined I have tried to upgrade sage and succeeded (5.9), but ./sage -combinat update failed with the last few lines being:Hunk #1 FAILED at 405 1 out of 4 hunks FAILED -- saving rejects to file doc/en/thematic_tutorials/coercion_and_categories.rst.rej patching file sage/categories/sets_cat.py Hunk #5 FAILED at 661 1 out of 5 hunks FAILED -- saving rejects to file sage/categories/sets_cat.py.rej patch failed, unable to continue (try -v) patch failed, rejects left in working dir errors during apply, please fix and refresh trac_14287-rebased.patch Abort I'm not sure whether the problem is from having an old version of sage -combinat or from something else, but any help would be appreciated. I am running Scientific Linux 6.4 x64 and *do not* have root access (university machine). I am also a beginner when it comes to *nix.
