Hi,

this is found on a cluster, it is running on Pythn 2.6.6, it is a 64 bit system
the svn tree is few days old, updating it now.

creating an issue here (it seems):
from grass.pygrass.modules.shortcuts import raster as r

Can you open a python2.6.6 shell and try this import:

from xml.etree.ElementTree import fromstring

Do you receive the same error?

Hi Yann,

I've compiled python2.6.6 and installed on my user home.
Then distclean and re-copile grass7 and it is working on my machine,
as you can see:

GRASS 7.0.svn (nc_basic_spm_grass7):~ > python
Python 2.6.6 (r266:84292, Jun 28 2013, 19:43:23)
[GCC 4.8.1] on linux3
Type "help", "copyright", "credits" or "license" for more information.

from grass.pygrass.modules.shortcuts import raster as r
from grass.pygrass.modules.shortcuts import imagery as i
from grass.pygrass.modules.shortcuts import display as d

I don't know how can I help you to solve this problem...

As you can see the error is raised from the internal libraries of python...

Maybe you can try re-compiling and installing python locally in your home...

Best regards
