LinuxCNC 2.9 Python module linuxcnc error

I want to use the compensation.py methode for autoleveling of my mill.
while loading linuxcnc the pyhton script tries to load the module linuxcnc but cannot find it.
I had to install numpy and spicy before but pip cannot find a module called linuxcnc. I assume the script is running on python 2 since I used pip and not pip3.
However python3 has a module that is named linuxcnc.

Maybe someone can point me into the right direction.
I am running LINUXCNC - 2.9.0-pre0-7877-g15792c421

Thanks

    

in linuxcnc 2.9 all python programs must use python3.

ok how can I tell linuxcnc to use pyhton3 and not 2?

how did you install linuxcnc?

with the package manager.
I started with the 2.8 iso and updated to 2.9.0-pre0-7877-g15792c421

My linuxcnc installation is using python2.
When I open python3 in the termianl and try
import linuxcnc
I get no error.
If I do that in python (2.x) <I get the error.

How can I use python3 for .py files?
