[GRASS-user] Grass too slow/freeze. Scripts works only on Qgis

[Davide Sponchiado]

Hi all
I got a great problem: i can't use Grass because it's slow and often freeze.
If i do some simple operation (v/r.in, remove ecc...) one time it did it 
in 0secs but 9 times it takes 1min and 30 secs. always.

But the great problem happens when i launch some scripts.
i look inside the task manager and i saw that g.remove, v.extract, 
v.to.points, and more are on but frozen. If i stop them throunght task 
manager, the script restarts (sometimes crash because it didn't complete 
the operation).


Same happens when i start Grass inside Qgis with the shell.
But if i run the script on Qgis it works normally.

i got Windows 8 and quadcore pc, but around i didn't find any problem 
with my config.

[GRASS-user] Python script works with Qgis but not in Grass

[Davide Sponchiado]

Hello to everyone,

i got Windows 8 with QGIS Dofour 2.0.1 e Grass 6.4.3 on my PC.

I got no problem when i run my script on Qgis but i need to fix some 
problems inside it and Qgis doesn't show you any log errors so i need to 
use Grass.

When i launch it some errors happens:

Launching script 'C:\Program Files\QGIS 
Dufour\apps\grass\grass-6.4.3\etc\gui\scripts\v.grass2hec_rev.py'...

Exception in thread Thread-75:
Traceback (most recent call last):

TypeError: environment can only contain strings

First of all I uninstall and reinstall Qgis and Grass many times trying 
to understand if the problem was in the x86 version or in some registry 
forgot in the previous versions (i control the regedit deleting manually 
all the files i thought related to Qgis and Grass).
Then, i remembered that I installed Python one month ago (not in the 
same folder), then i uninstall it.
I fear to forgot some other registry but nothing is shown directly in 
the registry. All the Python27 are deleted.


Now i reinstall QGIS and Grass (version i told before) but still it 
doesn't work.


Really need a big help.
