Re: [GRASS-user] GRASS GIS based developing tools
Hi Vaclav,
first of all thanks for your feedback, I beg your pardon it seams the link was
just poiting to the readme file, this should be the link to the complete gist:
https://gist.github.com/manuelep/e56fe90399c44e02e7cb97d5ef95edbd
anyway you can even clone the complete repo that contains both files using: git
clone https://gist.github.com/e56fe90399c44e02e7cb97d5ef95edbd.git jupyter-grass
and then follow other instructions reported in the README:
cd jupyter-grass
mkdir notebook-home
docker-compose build --build-arg user="${USER}" --build-arg uid="${UID}"
docker-compose up
Let me know if something is not clear or goes wrong...
Thanks a lot
Cheers

Hi Manuele,
Seeing a setup with JupyterLab is always nice and useful especially if the
focus is developing and distributing GRASS procedures. A standalone repository
with everything needed would be a good starting point for sharing such a setup
and making it ready to go. I don't see a Dockerfile, but it seems it is needed.
You can compare your setup to docker and binder directories in the
https://github.com/OSGeo/grass/ and describe how your setup is different.
Best,
Vaclav

The main developing proposed tool in the architecture is Jupyter Lab, I don't

I just wanted to have some feedback to understand if it can be considered a

Unfortunately the readme file at the moment is in italian but the compose file

Hm…
Did you initialize the session, e.g. like:
with Session(gisdb="/tmp", location="location", create_opts="EPSG:4326"):
from grass.pygrass.vector import Vector
Yes it's exactly what I do, the strange fact is that I can by-pass the
exception assigning the LD_LIBRARY_PATH value before running the script even if
even now before importing vector lib this env variable has the correct value
exactly thanks to the grass_session lib import...
so the script modified as you suggested reported here under still raise the
exception
# -*- coding: utf-8 -*-
import os, sys
GISBASE = '/usr/lib/grass78'
GRASSBIN = '/usr/bin/grass78'
# Define GRASS-Python environment
os.environ['GISBASE'] = GISBASE
os.environ['GRASSBIN'] = GRASSBIN
sys.path.append(os.path.join(GISBASE, "etc", "python"))
from grass_session import Session
import grass.script as gs
print(f"LD_LIBRARY_PATH: {os.environ['LD_LIBRARY_PATH']}")
print(f"GRASSBIN: {os.environ['GRASSBIN']}")
with Session(gisdb="/tmp", location="location", create_opts="EPSG:4326"):
from grass.pygrass.vector import Vector
print('DONE!')
while the old script (for convenience reported here under) runned as
$ LD_LIBRARY_PATH=$(grass78 --config path)/lib python import_test.py
LD_LIBRARY_PATH: /usr/lib/grass78/lib
GRASSBIN: /usr/bin/grass78
DONE!
returns just what printed in the script without raising the exception.
# -*- coding: utf-8 -*-
import os, sys
GISBASE = '/usr/lib/grass78'
GRASSBIN = '/usr/bin/grass78'
# Define GRASS-Python environment
os.environ['GISBASE'] = GISBASE

sys.path.append(os.path.join(GISBASE, "etc", "python"))
# from grass_session import Session

print(f"LD_LIBRARY_PATH: {os.environ['LD_LIBRARY_PATH']}")

Drear Stefan,
thanks for your quick reply but the solution is not so clear, I already use
grass_session library even if not reported in the attached example, how can it
helps with the issue? Just import the vector library after the session is
loaded does not solve as far

Dear Manuele,
For ctypes in pygrass, the C-libraries need to be loaded explicitly.
