I found the solution.
I know we don’t use julia the right way. We run every script in the global environment (but we wanna change it soon)
BUT - the solution was:
I put
import Pkg
Pkg.activate()
at the very beginning of each script.
Thanks for all the help
Edit:
Not sure if the obove was the solution.
I just found out that JULIA_NUM_THREADS=4
was also needed.
