Can't import ROOT using PyROOT

Hi All,

I intend to use PyRoot in analyzing a ROOT file, but I get the following error:

File "pyroot_ex_delete.py", line 1, in <module>
import ROOT
ModuleNotFoundError: No module named 'ROOT'

As per this post, executing root-config --has-python on WSL gives me a no

I am able to use ROOT though. Can anyone please assist me in installing PyRoot to a system with already-installed ROOT?

I think @etejedor can help you.

Hello,

PyROOT cannot be installed separately from ROOT as of today, I would recommend you do a second installation of ROOT if the one you have does not have PyROOT.

conda could be a good option:

Note that the correct option in recent ROOT versions is --has-pyroot, not --has-python :grimacing: (EDIT: even more recent ROOT versions will actually complain when root-config is passed an invalid option rather than just replying “no”).

How did you install ROOT? Can you start the prompt running the root command from the terminal?
