Authors: * Min RK * Mark Sienkiewicz * Matthias Bussonnier To download and install MathJax: From Python: >>> from IPython.external.mathjax import install_mathjax >>> install_mathjax() From the command line: $ python -m IPython.external.mathjax To a specific location: $ python -m IPython.external.mathjax -i /usr/share/ will install mathjax to /usr/share/mathjax To install MathJax from a file you have already downloaded: $ python -m IPython.external.mathjax mathjax-xxx.tar.gz $ python -m IPython.external.mathjax mathjax-xxx.zip It will not install MathJax if it is already there. Use -r to replace the existing copy of MathJax.
