Inappropriate ioctl for device

I am trying to run

%display unicode_art

Partitions(5).list()

In the terminal, this works fine, but in the jupyter notebook I get the error "Inappropriate ioctl for device". There are also issues for any other entry using unicode art.

I am on Sage 9.5, Ubuntu 22.04, and Firefox 99.0.1 (installed as .deb not as snap).

unicode art is made for the terminal. For jupyter, we may need to use something from https://ipython.readthedocs.io/en/sta...

%display latex is more appropriate for the Jupyter notebook --- well, not for Partitions(5).list()...

Here is a partial traceback

As you can see, this comes from asking about the terminal width..

----> 6         print(self.p._unicode_art_())
~/sage/local/lib/python3.9/site-packages/sage/structure/sage_object.pyx in sage.structure.sage_object.SageObject.__repr__ (build/cythonized/sage/structure/sage_object.c:2558)()
    192         except AttributeError:
    193             return super().__repr__()
--> 194         result = reprfunc()
    195         if isinstance(result, str):
    196             return result

~/sage/local/lib/python3.9/site-packages/sage/typeset/character_art.py in _repr_(self)
    153             hsize = MAX_WIDTH
    154         else:
--> 155             hsize = self._terminal_width()
    156         # if the draw is larger than the max length, try to split it
    157         if hsize <= self._l and self._breakpoints:

~/sage/local/lib/python3.9/site-packages/sage/typeset/character_art.py in _terminal_width(self)
    281         import termios
    282         import struct
--> 283         rc = fcntl.ioctl(int(0), termios.TIOCGWINSZ,
    284                          struct.pack('HHHH', sys.stdout.fileno(), 0, 0, 0))
    285         h, w, hp, wp = struct.unpack('HHHH', rc)
