ok, sorry for being so dumb and unclear. Please be patient. Let me try to be more clear. Currently I do that:
* enter a python3 virtual env (using source mypy3/bin/activate) * cd sage/src * launch ipython * import sage * from sage.interfaces.all import * resulting in ImportError: No module named 'sage.misc.lazy_import' So my question is: what is the cause of this error ? The same error happens for several cython modules. Frederic Le vendredi 10 juin 2016 20:59:31 UTC+2, Volker Braun a écrit : > > Whats your question > > a) you want to build Sage in a py3 environment?
