ROOT module not found: Python3

matthewlee4123 · May 14, 2020, 4:05pm

ROOT Version: 6.20.04 source
Platform: WSL Ubuntu 20.04
CMake version: 3.16.3
Python3 version: 3.8.2
Python version: 2.7.18

Hello -

I have been pulling my hair out the last few days trying to successfully install ROOT/PyROOT with Python3 and I was hoping someone could help. I am very new to the terminal, so please forgive my ignorance. I am able to successfully build and run ROOT in c++, however when I check “root-config --has-python” I get “no”. I am also unable to “import ROOT” in my Python3 scripts. Please note that I am looking to write in Python3, and I have no need for Python2 compatabilitiy.

Below are the steps I took, please let me know if I can provide more information:

I installed the source file and all required and optional prerequisite packages. I received the following message when installing the optional packages:

Note, selecting ‘libglu1-mesa-dev’ instead of ‘xlibmesa-glu-dev’
Note, selecting ‘libglew-dev’ instead of ‘libglew1.5-dev’
Note, selecting ‘libgraphviz-dev’ instead of ‘graphviz-dev’
Note, selecting ‘python-dev-is-python2’ instead of ‘python-dev’
Note, selecting ‘libgsl-dev’ instead of ‘libgsl0-dev’
Package libqt4-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Per a suggestion on another post here I also installed python3-dev
After tarring the source file, I cmake with:

cmake …/root-6.20.04/ -DPYTHON=ON -Dpyroot=ON -Dpyroot_experimental=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 -DPYTHON_INCLUDE_DIR=/usr/include/python3.8m -DPYTHON=/usr/lib/x86_64-linux-gnu/libpython3.8m.so.1

Here I noticed that I seemed to successfully point ROOT to Python3 and not Python2. I know certain things have failed to be built/found, I am unsure if these are critical or just options.
At this point I check “root-config --has-python” and “root-config --has-python3” and I receive “no”
In my ROOT config file it shows:

BUILDPYTHON := yes
252 PYTHONLIBDIR :=
253 PYTHONLIB :=
254 PYTHONINCDIR := $(filter-out /usr/include, /usr/include/python3.8m)
255 PYTHONLIBFLAGS :=
256 PYTHONEXE :=

After building root, I still have “root-config --has-python” and “root-config --has-python3” giving “no”
I now notice that /root/lib/libPyROOT.so does not exist. However, I do not know why or how I can rebuild it correctly.

Please let me know if you have any suggestions!

Thank you.

I assume root-config --features shows “pyroot” (and possibly “pyroot_experimental”) so everything is fine. I guess they are enabled for “python3”.
You can also explicitly try “root-config --has-pyroot” (and “root-config --has-pyroot_experimental”) if you like.

BW. Try also e.g. root-config --has-python3-feature-check-any-meaning

matthewlee4123 · May 15, 2020, 8:46am

Thank you for your reply!

Yes, it does show pyroot and pyroot_experimental. However, I cannot find the libPyROOT.so file in my /root/lib directory so Python scripts give the error “ModuleNotFoundError: No module named ‘ROOT’” since my PythonPATH points to root/lib/.

I did try root-config --has-python3-feature-any-meaning and got back “no”

Wile_E_Coyote · May 15, 2020, 8:49am

What do you get from:
root-config --prefix
root-config --libdir
root-config --cflags

matthewlee4123 · May 15, 2020, 8:51am

root-config --prefix -> /home/matthewlee4123/Products/root
root-config --libdir -> /home/matthewlee4123/Products/root/lib
root-config --cflags -> -pthread -std=c++11 -m64 -I/home/matthewlee4123/Products/root/include

Wile_E_Coyote · May 15, 2020, 8:52am

It seems to me that the building of ROOT died somewhere in the middle.
Try to restart it: “cd your_build_dir” and then: “make > make.out.txt 2>&1” (then inspect the newly crated “make.out.txt” file).

matthewlee4123 · May 15, 2020, 9:08am

The make.out.txt file is over 400 lines, but each line begins with ‘[XX%] Built Target …’

I can paste here if you would like to take a look though.

Wile_E_Coyote · May 15, 2020, 9:13am

Check around “Built target” lines which contain “move_header_bindings_pyroot”, “move_header_tmva_pymva”, “G__PyROOT”, “PyROOT”, “G__PyMVA”, “PyMVA”.

Has “make” (re-)built anything now?

If there are no problems reported then I have no idea what failed and how.

matthewlee4123 · May 15, 2020, 9:21am

Actually none of these lines exist in my make file.

I am unsure to check if anything new was built…

Wile_E_Coyote · May 15, 2020, 9:25am

Attach the “make.out.txt” file here.

In order to see what what’s new, you could try:

ls -alt `root-config --libdir`

matthewlee4123 · May 15, 2020, 9:28am

make.out.txt (14.7 KB)

Wile_E_Coyote · May 15, 2020, 9:30am

My mistake (I don’t use “pyroot_experimental”) … you do have “move_header_bindings_tpython”, “G__ROOTTPython” and “ROOTTPython”. so have you tried to use it:

[...]$ python3
import ROOT

matthewlee4123 · May 15, 2020, 9:37am

Yes, I have tried

import ROOT

in the python and python3 environments. I get the “No module named ‘ROOT’” error in both. Specifically:

Traceback (most recent call last):
File “”, line 1, in
ModuleNotFoundError: No module named ‘ROOT’

Wile_E_Coyote · May 15, 2020, 9:42am

@Axel We need someone who knows how “pyroot_experimental” is expected to behave (and why it fails).

matthewlee4123 · May 15, 2020, 9:46am

@Wile_E_Coyote, thank you very much for your time!

Wile_E_Coyote · May 15, 2020, 9:47am

Just to make sure … do you actually setup your ROOT before calling python?

[...]$ source /full/path/to/your/root/bin/thisroot.sh
[...]$ python3
import ROOT
