Hello,
I wrote the solution implemented in the hope that it serves at someone else.
The Situation
=========
I wrote a script using basemap and matplolib. which draw a map.Dread a
file containing a bunch of Genbank accession numbers, and downloaded
the Genbank records:
....
from pylab import *
import os, sys
import os.path
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
map = Basemap(projection='cyl', resolution='l')
map.drawcoastlines()
map.drawmapboundary()
...
This worked fine as a script, but when I attempted to turn it into a
Windows executable with py2exe and the setup.py script:
"""
from distutils.core import setup
import py2exe
from distutils.core import setup
import py2exe
import glob
import matplotlib
opts = {
'py2exe': { "includes" : ["sip", "PyQt4", "matplotlib.backends",
"matplotlib.backends.backend_qt4agg",
"matplotlib.figure","pylab", "numpy",
"matplotlib.numerix.fft","mpl_toolkits.basemap",
"matplotlib.numerix.linear_algebra",
"matplotlib.numerix.random_array",
"matplotlib.backends.backend_tkagg"],
# 'excludes': ['_gtkagg', '_tkagg','_agg2','_cairo',
'_cocoaagg', '_fltkagg', '_gtk', '_gtkcairo', ],
'dll_excludes': ['libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll']
}
}
data_files = [(r'mpl-data',
glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\*.*')),
# Because matplotlibrc does not have an extension,
glob does not find it (at least I think that's why)
# So add it manually here:
(r'mpl-data',
[r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\matplotlibrc']),
(r'mpl-data\images',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\images\*.*')),
(r'mpl-data\fonts',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\fonts\*.*'))]
setup(windows=[{"script" : "myapp.py",
"icon_resources": [(1, "myapp.ico")]}, ],
version = "1.0",
options=opts, data_files=data_files)
with the command python setup.py py2exe, attempting to run the
resulting myapp.exe would throw an error.
The Error
========
This is the error thrown on running the executable:
Traceback (most recent call last)
File "myapp.py", line 40, in <module>
File "mpl_toolkits\basemap\__init__.pyc", line 774, in __init__
File "mpl_toolkits\basemap\__init__.pyc", line 848, in _readboundarydata
IOError: Unable to open boundary dataset file. Only the 'crude', 'low',
'intermediate' and 'high' resolution datasets are installed by default.
If you are requesting a 'full' resolution dataset, you may need to
download and install those files separately
(see the basemap README for details).
The Problem
==========
Location of basemap data
The problem is identified when basemap is imported, the code of
basemap/__init__.py try to establish the basemap data directory in the
library.zip file.
[install dir]\dist\library.zip\mpl_toolkits\basemap\data
Under normal script-like execution, it works, the path is a string
indicating a location accessible through the filesystem . However with
py2exe, the location of data basemap directory is located within the
shared zip archive that py2exe creates and the above error is thrown.
The Solution
==========
The solution came in three times
1. Add mpl_toolkits.basemap in the option list (setup.py)
#--------------------------------------------
opts = {
'py2exe': { "includes" : ["sip", "PyQt4", "matplotlib.backends",
"matplotlib.backends.backend_qt4agg",
"matplotlib.figure","pylab", "numpy",
"matplotlib.numerix.fft","mpl_toolkits.basemap",
"matplotlib.numerix.linear_algebra",
"matplotlib.numerix.random_array",
"matplotlib.backends.backend_tkagg"],
#--------------------------------------------
2. Add basemap\data in data_files list
#--------------------------------------------
data_files = [(r'mpl-data',
glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\*.*')),
(r'mpl-data',
[r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\matplotlibrc']),
(r'mpl-data\images',glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\images\*.*')),
(r'mpl-data\data',glob.glob(r'C:\Python25\Lib\site-packages\mpl_toolkits\basemap\data\*.*')),
#---------------------------------------------
3. Modification of
C:\Python25\Lib\site-packages\mpl_toolkits\basemap\__init__.py
Near l.50, add the block "check if it turns into a Windows executable
with py2exe"
if 'BASEMAPDATA' in os.environ:
basemap_datadir = os.environ['BASEMAPDATA']
if not os.path.isdir(basemap_datadir):
raise RuntimeError('Path in environment BASEMAPDATA not a directory')
else:
basemap_datadir = os.sep.join([os.path.dirname(__file__), 'data'])
#-----------------------------------------------
# Check if it turns into a Windows executable with py2exe
import re
if (basemap_datadir.find("library.zip") > -1):
basemap_datadir=re.sub("library.zip","",basemap_datadir)
basemap_datadir=re.sub("mpl_toolkits","mpl-data",basemap_datadir)
basemap_datadir=re.sub("basemap","",basemap_datadir)
#-----------------------------------------------
This works under normal script execution and in py2exe mode.
