[GRASS-user] Using grass.script in Jupyter (Azure)

[Mehrdad Varedi]

Hi Vaclav,
Thanks for your email, I could run the following lines with no problem in
Jupyter:

import os
import sys
import subprocess
from IPython.display import Image

# create GRASS GIS runtime environment
gisbase = "f:\PROGRA~1\QGIS2~1.18\apps\grass\grass-7.4.1".strip()
os.environ['GISBASE'] = gisbase
sys.path.append(os.path.join(gisbase, "etc", "python"))


although when tried to run the following:

import grass.script as gs
import grass.script.setup as gsetup

again I got some errors:

ModuleNotFoundError                       Traceback (most recent call
last)f:\PROGRA~1\QGIS2~1.18\apps\grass\grass-7.4.1\etc\python\grass\script\core.py
in <module>()     38     # python2---> 39     import __builtin__
40     from os import environ
ModuleNotFoundError: No module named '__builtin__'

During handling of the above exception, another exception occurred:
ImportError                               Traceback (most recent call
last)<ipython-input-3-cd30798f91ed> in <module>()----> 1 import
grass.script as gs      2 import grass.script.setup as gsetup
f:\PROGRA~1\QGIS2~1.18\apps\grass\grass-7.4.1\etc\python\grass\script\__init__.py
in <module>()      3 from __future__ import absolute_import      4
----> 5 from .core   import *      6 from .db     import *      7 from
.raster import *
f:\PROGRA~1\QGIS2~1.18\apps\grass\grass-7.4.1\etc\python\grass\script\core.py
in <module>()     42     # python3     43     import builtins as
__builtin__---> 44     from os import environb as environ     45
unicode = str     46 __builtin__.__dict__['_'] =
__builtin__.__dict__['_'].__self__.lgettext
ImportError: cannot import name 'environb' from 'os'
(f:\ProgramData\Anaconda3\lib\os.py)



Do you have any idea why it is happening?



I have windows 10 on this machine and grass version 7.4.1 is installed.


Thanks,


Mehrdad
