I tried it in sage 9.2 nice printing.
But in sage I use show(LatexExpr("r \mu \epsilon))
μϵ
I am not sure that what you want (and naturaly first command in cell
%display latex in sage)
One can even format text in a beautifull latex
show(LatexExpr(r"This \ is \ \mu \ and \ \epsilon"))
Thisisμandϵ

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 <class 'bytes'> 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.
