Thanks! I just discovered that there is a separate group for Sage Cell.
Oddly, the SageCell page links here for help! Apologies for not posting
there first.

I'm teaching a linear algebra course where we use the Sympy Python
package for a lot of the computations. This includes a PreTeXt textbook
where there are Sage Cells throughout, with sample code supplied.
Until today (I think it was working yesterday), I've had no trouble
running code like the following:
from sympy import Matrix, init_printing
init_printing()
A = Matrix([[1,2,3,4],[5,6,7,8],[9,0,1,2]])
display(A.rref())
The init_printing function from Sympy renders the output in MathJax
rather than pretty-printed plain text, which is nice for teaching. I can
run this with the language set to either Sage or Python. (the 'display'
command is only needed for Python, which is funny, because it is not
needed
in Jupyter with a Python kernel.)
Right now this code throws about 50 lines of error messages; the main
error is a Type Error:
TypeError: Object of type with value of '(a very, very
long string that I won't reproduce here)' is not JSON serializable
Was there a change made today that would cause this error? Maybe in the
Sympy library? If I remove the init_printing() line, everything works,
except that there's no longer nice display for the output.
The reason for using Python syntax is that we also do labs in Jupyter
notebooks. Our institution has a Jupyter hub with Python and R kernels,
but
no Sage kernel. (We do not have a CoCalc subscription.)
I know there is a Sage equivalent to init_printing (although I forget
what it is) but that won't work on the Jupyter side.

Re: [sage-support] init_printing from sympy is no longer working in SageCell
This is due to recent upgrade to Sage 9.5. I will try to have it fixed in a
few hours or revert to 9.4 until I figure out the fix.

Re: [sage-support] init_printing from sympy is no longer working in SageCell
Here is an example with Sage cells in context:
https://opentext.uleth.ca/Math3410/sec-kernel-image.html#p-283-part2
If I remove the init_printing() line, or change this to
init_printing(use_latex=False), the code will run, but I lose the
MathJax-formatted output.
I can't tell if this is a bug in the init_printing() function (to my
knowledge, there is no recent update to Sympy -- I upgraded my local Python
installation and everything is still working) or if something is going
wrong with Sage Cell trying to process the output.

Re: [sage-support] init_printing from sympy is no longer working in SageCell
This is in SageMathCell, rather than in a local installation of Sage. I
don't think there's much I can do about what is running on here.
