[GRASS-user] Getting an error using r.mask in a GRASS shell script

GRASS GRASS user
1

All:

I have a GRASS bash shell script where all my GRASS commands (7.0.0beta3) execute just fine except for my call to set a MASK:

r.mask --overwrite input=$basin_mask@$MAPSET

I get this error…

Traceback (most recent call last):
File “/usr/local/grass-7.0.0beta3/scripts/r.mask”, line 71, in
import grass.script as grass
ImportError: No module named grass.script

I have never previously encountered this kind of thing calling r.mask in any of my GRASS scripts.

Any thoughts??

Thank you,

Tom

There is no input parameter in G7:r.mask [1]. This info is however missing in [2], as I just noted. I am not sure of the behaviour of 7.0.0beta3, but my GRASS 7.1.svn comes up with:

ERROR: Sorry, <input> is not a valid parameter

The lookup mechanism should now work fine (otherwise please report),
just beta3 didn't have it yet.

Markus,

Thank you for your help; I did try using RC1 (which I built shortly after it’s release) and got the same error – but I’ll try again. I can’t do that right now because I just kicked-off something else in a different GRASS LOCATION that’s taking a while to process. So, I won’t be able to try again until later.

Thank you,

Tom

Anna,

I’m building RC1 on a different Linux box (where I had beta3); I’ll try again and if I get the same error, I’ll offer up an example — how would I do that? tar things up and put it on GoogleDrive?

I was thinking ideally about a short .sh file which can be attached. I

Anna,

Below is my script. I am running on Ubuntu 10.10, GRASS 7 RC1 (built today). I have tried running my script two ways:

(1) external from GRASS, where I set the GRASS environment (the attached script) — this is how I have done almost all my GRASS scripting for years

(2) I remove the section where I set the GRASS environment and run from the GRASS prompt — this works perfectly fine!!! (I had not tried this previously when I first reported this problem)

Running as (1) is where I get the r.mask errors I have been seeing; I get the errors both when I simply remove any existing MASKs (r.mask -r) or where I attempt to set the MASK.

Cheers!
Tom

#!/bin/bash

Read the GRASS LOCATION and BASIN MASK as command line arguments

location=$1

basin_mask=$2

Can you please post again what are the errors. It is not clear from the

not a screenshot, or just copy and paste the script to the email if it is
short enough.

Vaclav,

That was not a screen shot, just fg & bg colors of the text (I copied & pasted from my Mac term window — sorry for the embellishments). The errors I have been getting is this:

Traceback (most recent call last):
File “/usr/local/grass-7.0.0beta3/scripts/r.mask”, line 71, in
import grass.script as grass
ImportError: No module named grass.script

same result for RC1. My script is attached…

I see it now. I was confused because it looks really bad at my end.

The errors I have been getting is this:

Traceback (most recent call last):
  File "/usr/local/grass-7.0.0beta3/scripts/r.mask", line 71, in <module>
    import grass.script as grass
ImportError: No module named grass.script

"ImportError: No module named grass.script" means that Python does not see
package (grass.script or also grass). You miss the PYTHONPATH variable
which says where Python packages are:

export PYTHONPATH="$GISBASE/etc/python:$PYTHONPATH"

See the following in case you are missing some other variable which would
be important for you (probably none now):

http://grasswiki.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly#Bash_examples_.28GNU.2FLinux.29

If you would have a lot of problems with setting the environment, use
GRASS_BATCH_JOB variable with the grass command (see grass70 --help).

I hope this helps,
Vaclav

Vaclav,

Fantastic; that did the trick! I figured the issue had to be something like that, but I just had not been able to find it and, until now, this had not been an issue.

Thank you very much…
