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. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
