Hi!
NEST 3.x (which is definitely what you should use) is indeed Python 3
only. Python 2 has been dead now since two and a half years... Here's
an article on how to build ROS with support for Python 3:

Cheers,

If I use the rosrun command I have:
salvo@salvo-Aspire-GX-781:~/Desktop/ros_ws/src/pacchetto_ros/scripts$ rosrun
pacchetto_ros
sub_vrep.py
Traceback (most recent call last):

ImportError: dynamic module does not define init function (initpynestkernel)
The problem maybe is due to the fact that to import nest i have to use python3 but
Melodic is based on python2...
