Hello all,
I have a notebook which fails to convert. I've already encountered the problem (see user list) a few weeks ago with another notebook. The message is the same:
johan$ ipython nbconvert Fit_wind.ipynb
[NbConvertApp] Using existing profile dir: u'/home/johan/.config/ipython/profile_default'
[NbConvertApp] Converting notebook Fit_wind.ipynb to html
[NbConvertApp] Support files will be in Fit_wind_files/
[NbConvertApp] Loaded template html_full.tpl
pandoc: option `--mathjax' requires an argument URL
Try pandoc --help for more information.
