Hello,
I am getting an error with savefig and pdf when I try to used matplotlib
with latex font rendering (attached below). In etc/matplotlibrc, I set
text.latex.preamble : \usepackage{MinionPro},
\renewcommand{\sfdefault}{Myriad-LF}
It seems that the dviread backend does not find a specific *.vf,
MinionPro-It--lcdfj.vf to be specific,
file that is not needed in my opinion. Any ideas how to solve that?
Thanks,
David
