[GRASS-user] GRASS 7 temporal module under Windows

GRASS GRASS user

Hi all,

I am pretty new with GRASS, so sorry for the more than likely stupid question.

I am trying to use the new temporal module in GRASS 7 running under Windows 7 (I am waiting for authorization to use it under Linux). I am following the example presented in the FOSS4G 2014 workshop (http://fatra.cnr.ncsu.edu/temporal-grass-workshop/) but when I try to register the temporal dataset I get an error. It has a lot of lines, but I think the key is in the following:

RuntimeError:

Attempt to start a new process before the

current process

has finished its bootstrapping phase.

This probably means that you are on Windows and

you have

forgotten to use the proper idiom in the main

module:

if name == ‘main’:

freeze_support()

…

The “freeze_support()” line can be omitted if

the program

is not going to be frozen to produce a Windows

executable.

I am just running the commands through the GUI, should I create a python script to resolve that “freeze_support()” issue? As I said, I am pretty new and that would take some time, that’s why I prefer to ask first if that’s the way…

Thank you in advance!!

Yes! I had to uninstall the version I was working with (grass7.0.0.svn) and installed grass7.0.0beta3 and with that one it worked. I must add that in the end I got an error when I tried to create an animation, that was my objective, but I could create the temporal datasets and work with them.

I hope this helps.

Cheers,

Jose.
