There is the do_pickle argument, e.g. from TFM: sage: class C: ....: @cached_method(do_pickle=True) ....: def __hash__(self): ....: return id(self)
Note that it can cause the following problem: Not every circularly dependent collection of cython objects can be pickled. Cached values can make the difference between what can an cannot be pickled. So whether or not pickling works can't reliably be tested in that case. On Thursday, June 27, 2019 at 5:07:04 AM UTC+2, Kwankyu Lee wrote: > > Hi, > > Suppose I have an object X.
