So far :
- Rebuild from scratch : sage command line crashes (same problem) - After sage -f ipython : ditto. In both cases, the sagemath Jupyter kernel works in both the Jupyter notebook and Jupyter lab sage -i <SomeSagePackage> also works. Worth a ticket <https://trac.sagemath.org/ticket/32852#ticket>…, whose priority I’m uncertain about. Obvious workaround : ./configure --with-system-python3=no && make HTH, Le mercredi 10 novembre 2021 à 12:31:06 UTC+1, Jan Groenewald a écrit : > Maybe sage -f ipython will fix it? > > > On Wed, 10 Nov 2021 at 13:22, Emmanuel Charpentier <emanuel.c...@gmail.com> > wrote: > >> Le mercredi 10 novembre 2021 à 10:49:28 UTC+1, dim…@gmail.com a écrit : >> >> >>> >>> On Wed, 10 Nov 2021, 09:45 Emmanuel Charpentier, <emanuel.c...@gmail.com> >>> wrote: >>> >>>> >>>> >>>> Le mercredi 10 novembre 2021 à 10:41:59 UTC+1, dim...@gmail.com a >>>> écrit : >>>> >>>>> it might be that you have to rebuild all the cython/python packages of >>>>> Sage. >>>>> >>>> >>>> That amounts to rebuilding from scratch, no ? >>>> >>> >>> not everything depends on python in Sage, e.g. GAP does not. >>> >>> at the very minimum, do >>> >>> make sagelib-clean >>> followed by >>> make build >>> >> No such luck : this crashes again.
