Get PyInstaller to import Basemap

Question

I\'m working on building a standalone executable for a simple tool I built that uses Basemap. (Using Python 2.7, using the dev version of PyInstaller - 2.1). The .exe (single

Answer 1

All you need to do is tell PyInstaller to add the basemap data to the distribution. Here is some sample code. Assuming that you have an ortho.py file in directory E:\scratch, put the following ortho.spec in the same directory and run it as

PyInstaller -y ortho.spec

Here is ortho.spec:

a = Analysis(['ortho.py'],
             pathex=['E:\\scratch'],
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='ortho.exe',
          debug=False,
          strip=None,
          upx=True,
          console=True )

import mpl_toolkits.basemap
import os

src_basedata = os.path.join(mpl_toolkits.basemap.__path__[0], "data")
tgt_basedata = os.path.join('mpl_toolkits', 'basemap', 'data')

coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas + Tree(src_basedata, prefix=tgt_basedata),
               strip=None,
               upx=True,
               name='ortho')

Answer 2

Took me a few days, but I think I sorted it from piecing together a few partial solutions:

From http://www.jontrinder.com/blog/?paged=2 :

In pyproj.py, found in C:...\Lib\site-packages\mpl_toolkits\basemap Just past the huge lists is a line that looks something like

pyproj_datadir = os.sep.join([os.path.dirname(__file__), 'data'])

Replace that with

if 'PROJ_DIR' in os.environ:
    pyproj_datadir = os.environ['PROJ_DIR']
else:
    pyproj_datadir = os.sep.join([os.path.dirname(__file__), 'data'])

The piece that was missing from the linked solution was then adding the data path when actually running PyInstaller with --paths

C:\Python27\python.exe "C:\Python27\Lib\site-packages\pyinstaller-develop\PyInstaller\main.py" --onefile --paths="C:\Python27\Lib\site-packages\mpl_toolkits\*" "C:\Documents and Settings\KAHERE\My Documents\Python code\Flood\src\root\nested\FloodRisk.py"

Just thought I'd post in case anyone else was banging their head on this one.
