I've been a reader in the Grass-users list so far but I wanted to
follow up with this:
I was trying to get a py script running under Grass 6.4 and 7.0
OS: WIndows 7 64 bit
Here are the results of my experiments, I will try to provide as much
detail as I can:
I am using http://svn.osgeo.org/grass/grass-addons/raster/r.ipso/ for my
tests:
GRASS64
I have GRASS 64 installed in C:\GRASS-64
I put the the r.ipso.py in C:\GRASS-64\scripts
I launch the GRASS 6.4.0 with MSYS
when I directly try to launch the module, I get this:
*GRASS 6.4> r.ipso.py
Traceback (most recent call last):
File "c:/GRASS-64/scripts/r.ipso.py", line 53, in <module>
import matplotlib.pyplot as plt
File "C:\GRASS-64\Python25\lib\site-packages\matplotlib\pyplot.py",
line 78, in <module>
new_figure_manager, draw_if_interactive, show = pylab_setup()
File
"C:\GRASS-64\Python25\lib\site-packages\matplotlib\backends\__init__.py", line
25, in pylab_setup
globals(),locals(),[backend_name])
File
"C:\GRASS-64\Python25\lib\site-packages\matplotlib\backends\backend_tkagg.py",
line 7, in <module>
import Tkinter as Tk, FileDialog
ImportError: No module named Tkinter*
I could workaround this problem by using the Python 26 installed
separately in C:\Python26 (which has numpy, matplotlib,
wx-2.8-msw-unicode (wxpython) etc)
apparently python26 interpreter can run the matplotlib better(?).
so I did:
*GRASS 6.4> export
PATH="/C/GRASS-64/lib:/C/GRASS-64/bin:/C/GRASS-64/scripts:/C/GRASS-64/tcl-tk/bin:/C/GRASS-64/sqlite/bin:/C/GRASS-64/gpsbabel:/C/GRASS-64/extralib:/bin:/C/Python26"
GRASS 6.4> export PYTHONHOME="/C/Python26"
*
note that I removed the C/Grass-64/extrabin to prevent the python.exe
there to interfere with my python.exe (the one in C:\Python26\) to
execute - If I don't remove C/Grass-64/extrabin from the PATH, here is
the result:
*GRASS 6.4> r.ipso.py
c:/Python26\lib\site.py:150: Warning: 'with' will become a reserved
keyword in Python 2.6
'import site' failed; use -v for traceback
Traceback (most recent call last):
File "c:/GRASS-70-SVN/scripts/r.ipso.py", line 52, in <module>
import os
File "c:/Python26\lib\os.py", line 758
bs = b""
^
SyntaxError: invalid syntax*
so anyway, I change the path as I mentioned above and the result is:
*GRASS 6.4> r.ipso.py
ERROR: Required parameter <map> not set:
(Name of raster map).
ERROR: Required parameter <image> not set:
(output graph).
Description:
Keywords:
raster
Usage:
r.ipso.py [-ab] map=name image=image [--verbose] [--quiet]
Flags:
-a generate ipsometric curve
-b generate ipsographic curve
--v Verbose module output
--q Quiet module output
Parameters:
map Name of raster map
image output graph
GRASS 6.4> *
so it works, I tried it with an input map and everything. It creates
the plot image and everything but the GUI does not launch (in linux it
does - everything works better there :) ). I want the GUI so that when I
create my own script I can check how the GUI looks etc.
I tried the same thing GRASS 7 too since it is all Python (which I love ! )
I get a different error when I go r.ipso.py just after launching GRASS
7.0.SVN with MSYS (Grass7.0 is installed in C:\GRASS-70-SVN - I mention
this to let you know that I don't go with the default C:\Program Files
(X86)\GRASS..... which has spaces in it and it creates all kinds of
problems - I see that it is been fixed, but I still feel this is safer)
*GRASS 7.0.svn> r.ipso.py
Traceback (most recent call last):
File "c:/GRASS-70-SVN/scripts/r.ipso.py", line 53, in <module>
import matplotlib.pyplot as plt
ImportError: No module named matplotlib.pyplot*
the reason (probably), C:\GRASS-70-SVN\Python25\Lib\site-packages does
not come with matplotlib - anyway I trick it again to look for libraries
under my Python26 by exporting:
*export
PATH="/C/GRASS-70-SVN/lib:/C/GRASS-70-SVN/bin:/C/GRASS-70-SVN/scripts:/C/GRASS-70-SVN/tcl-tk/bin:/C/GRASS-70-SVN/sqlite/bin:/c/GRASS-70-SVN/gpsbabel:/c/GRASS-70-SVN/extralib:/bin:/c/Python26"
export PYTHONHOME="/C/Python26"*
again note that I don't have the extrabin folder in the PATH
*GRASS 7.0.svn> r.ipso.py
ERROR: wxGUI requires wxPython. No module named wxversion
GRASS 7.0.svn>
*
This is where I am at right now - it seems that it is going to work out
if I figure out this last "ERROR: wxGUI requires wxPython. No module
named wxversion" problem in Grass-70.
Any ideas, suggestions ?
I just want to be able to launch the GUI when I have a .py of my own
under /scripts in grass6.4 or 7.0
thanks
