I'm having serious trouble getting cx_Freeze and matplotlib to agree
where the mpl-data folder is on an Ubuntu 14.04 machine.
I'm configured with python3-matplotlib 1.3.1 having come from the Ubuntu
repositories, and a (now slightly modified) cx_Freeze 4.3.4 from the
cheese shop.
Originally I couldn't even get cx_Freeze to locate the mpl-data folder
when freezing the package. I got around that by hacking the matplotlib
hook from:
def load_matplotlib(finder, module):
"""the matplotlib module requires data to be found in mpl-data in the
same directory as the frozen executable so oblige it"""
dir = os.path.join(module.path[0], "mpl-data")
finder.IncludeFiles(dir, "mpl-data")
to:
def load_matplotlib(finder, module):
"""the matplotlib module requires data to be found in mpl-data in the
same directory as the frozen executable so oblige it"""
try:
from matplotlib import get_data_path
dir = get_data_path()
except ImportError:
dir = os.path.join(module.path[0], "mpl-data")
finder.IncludeFiles(dir, "mpl-data")
So now the freeze copies mpl-data into build/exe.linux-x86_64-3.4/mpl-
data, but when I run my code:
print('Matplotlib resource file:', matplotlib.matplotlib_fname())
print('Matplotlib rcParams["datapath"]:', matplotlib.rcParams
["datapath"])
print('Matplotlib data folder:', matplotlib.get_data_path())
I get:
Matplotlib resource file: /etc/matplotlibrc
Matplotlib rcParams["datapath"]: /usr/share/matplotlib/mpl-data
Matplotlib data folder: /usr/share/matplotlib/mpl-data
So I copy in matplotlibrc, and set the datapath to hardcode the current
program directory; ugly but workable. And now I get:
Matplotlib resource file: /home/rgaddi/Documents/Software/rsctest/build/
exe.linux-x86_64-3.4/matplotlibrc
Matplotlib rcParams["datapath"]: /home/rgaddi/Documents/Software/
rsctest/build/exe.linux-x86_64-3.4/mpl-data
Matplotlib data folder: /usr/share/matplotlib/mpl-data
It recognizes that I've set the datapath, but it still will only use the
global system directory, thus defeating the point of the freeze.
I'm pretty much out of ideas at this point. Anyone have any advice?
