I wanted to do some quick calculations and I was too lazy to open a notebook file, so I just opened an IPython session in the terminal. According to sympy’s documentation calling sympy.init_printing() should initialize pretty printing in a python or IPython session. However, when I tried it, I didn’t get pretty printing:

I tried running with use_latex="mathjax"/True/False, use_latex=True/False, and I tried using IPython.display.display(). Nothing worked. I always get the raw version of my expressions like in the image above. What am I missing here? How can I enable pretty printing in a terminal session with sympy?
