[Matplotlib-users] Error when importing pyplot from matplotlib: »invalid literal for float(): 19#«

[knight91 <kni...@we...>]

Python claims to be unable to import pyplot. Apart from that, it has been
running absolutely fine.

I tried different versions of matplotlib, the one provided in my package
manager (apt-get) and two (stable & last stable) releases compiled from
source. I reinstalled all packages containting "python" on my system (Ubuntu
14.04 LTS). This error still occurs and prevents me from using pyplot.

What should I try next?

You have an afm font file with a badly formed header.  I thought this was
fixed on the master branch though....

[knight91 <kni...@we...>]

Okay, is there a way to get an afm font file with a nicely formed header? How
could I try to solve this problem?

I don't know for certain, but perhaps the font-forge program has a repair
utility? http://fontforge.github.io/en-US/

[Thomas C. <tca...@gm...>]

Also try deleting your font cache.

Have you tried with the master branch?
