Hello all,
I try to import with GRASS78 in parallel Sentinel-2 data with
"i.sentinel.import -r" (Multicore VM (32 cores -> 31 parallel processes)).
Sometimes the following error occurs (note the formatting comes from deploying
in actinia):
...

"90..99..96..100",
"99..93..100",

I found out that r.import uses temp_region and that this sets an environment
variable WIND_OVERRIDE:
https://github.com/OSGeo/grass/blob/4dc36bb86fa9181259fa7f9b9472f8d3bc4e787e/lib/python/script/core.py#L1281
os.environ['WIND_OVERRIDE'] = name
And in parallel processing the variable is set by each process and the
temp_region can be deleted to early.
Does anyone know if this is the reason of my error and how to fix this?
Best,
Anika
