Dear list,
I am struggling with my python code.
I am trying to get the computational region of a xyz-file. If I use
r.in.xyz in GRASS itself, it works all just fine, but using it in python
I always get an error.
Here is my code:
from grass_session import Session
from grass.script import
Dear all,
I have a numpy array with x,y, z coordinates that I would like to write to a
rater map.
When I convert the array to a StringIO-object and feed it to r.in.xyz I get:
OSError: [Errno 7] Argument list too long
I checked the content of the StringIO object and it contains only three columns
Dear Jonathan,
the error is due to grass_session that is not creating the location if
missing.
I don't have time in this day to fix this issue in grass_session, so the
fastest fsolution at the momenth is to check and create what is needed step
by step.
I did not have xyz file to test so I've only
Isn't the problem that you have there r.in_xyz instead of r.in.xyz?

Dear Moritz,
thanks for the answer and the examples. I'll try to put the functions and files
in this format and test them like that.I am not sure how to build these
makefile files but I'll try to follow the patterns I find in the other examples
of modules.Once this is done, I'll post it here.

OK, found it!
Reading the manuals more carefully helps:
So, with my StringIO object "result", formated x y z, the following works:
grass.write_command('r.in.xyz', stdin=result.getvalue(), input='-',
output=output,
method='mean', separator=' ')
StringIO c
Hi Helmut,
I have been installing r.vif as you have indicated (i.e. by downloading from
the server using g.extension and opening the tree of installable raster
addons), but can now confirm after installing both the new and old versions of
r.vif on a Windows 10 (64 bit) machine, that r.vif isn't

StringIO can be replaced with BytesIO BTW, though I don`t know what difference
the two make...
Out of curiosity I did a search. https://stackoverflow.com/a/37463095

Hi Dinarzarde and Helmut
I checked on Windows (grass 7.4.0 installed using osgeo4w), and
installing r.vif using g.extension works fine, but after installing it
does not appear in the addon list in the Modules tab. The same is true
for a number of other addons I installed. There are, on the oth
Many thanks Paulo and Helmut. Have an osgeo4w installation of grass 7.4.0, so
will run it on the console.
Best wishes,
Dinarzarde

Thanks, Nikos!
Interesting! Not 100% sure though, how to conclude from that post.
One voice there says "the two are not comparable one should use BytesIO, when
input data is bytes, and StringIO when Input data is string".
However in the this case, both seem suitable. So, the performance comparison
