Answer 1

Using colab's mathjax and setting the configuration file to TeX-MML-AM_HTMLorMML worked for me. Below is the code:

from sympy          import init_printing
from sympy.printing import latex

def colab_LaTeX_printer(exp, **options):  
    from google.colab.output._publish import javascript 

    url_ = "https://colab.research.google.com/static/mathjax/MathJax.js?"
    cfg_ = "config=TeX-MML-AM_HTMLorMML" # "config=default"

    javascript(url=url_+cfg_)

    return latex(exp, **options)
# end of def

init_printing(use_latex="mathjax", latex_printer=colab_LaTeX_printer)
