Dear Moritz,
Thank you for your advise and I just cut and paste the text from the terminal. I am \
making a bit of progress, as shown in the text below. I am not sure why it can't \
find the grass_session as I installed it using the PIP command. The only solution I \
can think of is that GRASS is using its own version of Python and not the Anaconda \
version.
bash-3.2$ export GRASSBASE="/Applications/GRASS-7.8.app/Contents/Resources/bin/grass78"
bash-3.2$ export GISRC="/Applications/GRASS-7.8.app/Contents/Resources/demolocation/.grassrc78"
bash-3.2$ export PATH="/Applications/GRASS-7.8.app/Contents/Resources/lib:/Applicatio \
ns/GRASS-7.8.app/Contents/Resources/bin:/Applications/GRASS-7.8.app/Contents/Resources/scripts"
bash-3.2$ python gapfill_v3.py
['/Users/shaffiqsomani/PySEBAL_dev/gapfilling', \
'/Applications/GRASS-7.8.app/Contents/Resources/lib/python38.zip', \
'/Applications/GRASS-7.8.app/Contents/Resources/lib/python3.8', \
'/Applications/GRASS-7.8.app/Contents/Resources/lib/python3.8/lib-dynload', \
'/Applications/GRASS-7.8.app/Contents/Resources/lib/python3.8/site-packages'] \
Traceback (most recent call last): File "gapfill_v3.py", line 20, in <module>
import grass_session
ModuleNotFoundError: No module named ‘grass_session'
Please let me know if you have any suggestions. Thanks so much for your assistance.
Kind Regards,
Shaffiq

Hi Shaffiq,
First of all please try to avoid using screenshots of the command line. You should be \
able to just copy-paste it's contents as text into your email which makes it much \
easier to read on most devices.

Thank you for your response since its greatly appreciated. Sorry, I just saw your \
message since it went into the spam folder. I have a couple of questions for you if \
you have a moment free. I looked at the Linux environmental variables which is \
export GRASS_BIN=/usr/bin/grass78, but changed it to GRASSBASE and opened up the \
unix file as shown in the screenshot below. I still get the following errors. Is \
there anything else that I am missing or should I be doing this another way. Thanks.
AFAIK, GRASSBASE is not used in GRASS GIS. Where did you get that from.
I would suggest to set that back to GRASSBIN and try again.
Moritz

I am trying to run grass as a Python script for the gapfilling component of PySEBAL \
where the GitHub directory is shown below. I have already imported the \
grass-session using the pip3 command.

The Windows Environmental Variable setup file is shown below which I tried to follow \
in the Jupyter Notebook and see if I can import GRASS. Unfortunately, I had no \
luck as shown in the screenshot.
set GRASSBIN=C:\OSGeo4W64\bin\grass78
As you can see here, GRASSBIN points to the actual 'binary' file that contains the \
GRASS GIS launch script (grass78). In your example it seems to me that you only point \
to the directory that contains it, not the actual file. Try adding the name of the \
file to your path.
