The use of a question mark (?) for help produces several deprecation warnings:

Am I doing something wrong?

A few questions :

  • What platform and OS are you using ?

  • How did you install Sage (i.e. compiled from tarball or installed from your distro) ?

  • Do you use Python 2 or 3 (IIRC, 9.1 will be the las Python 2-compatible release) ?

  • What interface (command line, Jupyter notebook, emacs, other) ?

FWIW, WorksForMe(TM) in 9.2.beta8 on Debian testing running on core i7.

Some answers:

  • The OS is Windows 10 running on a PC.

  • I installed Sage by downloading the installer from this web page: http://ftp.rediris.es/mirror/sagemath...

  • As fas as I know, the 9.1 version of Sage uses Python 3. I guess I do not understand the third question...

  • The interface I use is Jupyter notebook. The deprecation warning appears the first time the question mark (?) is used. It does not appear when using version 8.9 of Sage on the same PC.

I don't remember having seen this problem reported for Unix/Mac platforms. As far as I can tell, this may be Windows-specific. This port is a beast to maintain ; a slght misconfiguration can happe, especially if the underlying Cygwin platform has moved...

You could try :

  • to report this issue on sage-support, and, if it seems platform-specific,

  • to open a Windows-specific issue on the Github page of this Windows installer.

HTH,
