Thank you that solved it with some tweaks. I added GRASSBIN to my Environment variables populated with the grass bat file instead of GISBIN. Then added 'lib', 'bin' and 'scripts' folders to PATH variable. Once I did that that I was able to import grass_session and grass. It appears to work fine without GISRC set. Ellen

Interestingly, our docker containers just started to suffer from a similar (same?) problem: File "/scripts/test_grass_session.py", line 3, in <module> import grass.script as grass ModuleNotFoundError: No module named 'grass' Weird, we need to investigate. Grass_session works for me with both python2.7 and 3 in a Osgeo environment with grass 7.8.3 For me, the import modules work in this order in both python versions after pip installation. >>> import grass_session >>> from grass_session import Session >>> import grass.script as grass For the final script to work, you will have to set environment variables, GISBIN (grass78 root folder) , GISRC (.grassrc78 file in demo location) and add grass78 'lib', 'bin' and 'scripts' folders to PATH variable. I run the script in python 3, where it worked without setting GISBIN and GISRC variables. I have only tested this approach in Windows 10 yet, and should work fine in Linux as well. Regards Sajid
