Thanks Stefan! It solves my problem... I opened an issue [1] to the
github repo of grass_session.



AFAUI, 0.5 introduced, among others, the fact that libs are not loaded 
by default unless explicitly requested:


https://github.com/zarch/grass-session/commit/b1d4c0fa574bdbd86716fb504ce05e8b449a9dfc#diff-6f5e014607121aae5fa1a45459276b57eceb9194cc53dd65413d973faf59dd87

I'm not 100% sure I understand how it works, but IIUC, you should be 
able to something like this (untested):


Session(gisdb="/tmp", location="location", create_opts="EPSG:4326", 
loadlibs=True)


Don't know what the rationale behind this change is, though.

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

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.
