# \mathbb test doesn't render properly

Hi all,

So I'm generating a figure for a paper and I'd like to be able to use something akin to ax.set_ylabel('$\mathbb{TEST}$')

The weird thing is sometimes I get an error when running the figure generation script (attached) and sometimes I don't. I also can't reproduce when it does or doesn't give an error. In either case, the text doesn't render as blackboard bold text, it's just normal Computer Modern Roman text (see attached figure). Also see attached a python script that reproduces the figure.

asd.pdf (54.3 KB)

script.py (521 Bytes)

error.txt (4.24 KB)

After some playing I have discovered that putting maplotlib.rc('text.latex', preamble='\usepackage{amsmath},\usepackage{amssymb}') fixes the issue of text rendering. However, when putting this value in the ~/.matplotlib/matplotlibrc file, I get the same error saying that \mathbb is undefined. Any ideas?

Regards,
-- Damon

So it turns out that

text.latex.preamble : '\usepackage{amsmath},\usepackage{amssymb}'

is not valid, but

text.latex.preamble : \usepackage{amsmath},\usepackage{amssymb}

is valid. Everything works fine now.
