2018-06-05 18:21:00 +0200 | asked a question | draw a tree diagram Good afternoon,
I have defined a recursive function and I would like to vizualise the 'calls' of the function trought a tree diagram. The nodes should be the elements of a group (Extended affine weyl group). So expressions of this type s0 |

2018-05-30 01:12:03 +0200 | commented answer | How to use @lru_cache I have used: from functools32 import lru_cache @lru_cache() and it works. However my functions takes elements that probably are not hashable. Indeed I get this error TypeError: <class 'sage.combinat.root_system.fundamental_group.fundamentalgroupofextendedaffineweylgroup_class_with_category.element_class'=""> is not hashable Why elements of a group are not hashable? Is there a way to use @lru_cache() for my function? |
