Hi!, recently I have started learning about root and have also clone the official root repository after forking it in github to solve one good first issue. But when I tried to open it in Visual Studio Code I have installed the root extension and can view the root files but whenever I try to open any…

Hi, after writing the command given by you I got a pretty large result e.g. sayang@DESKTOP-IFS80HM:~$ echo $PYTHONPATH sayang@DESKTOP-IFS80HM:~$ echo $PATH /home/sayang/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/mnt/c/Program Files/WindowsA…

Hi, you still have an empty PYTHONPATH (see my comment above), so maybe you are not calling source /path/to/your/root/installation/bin/thisroot.sh ? Cheers, Enrico

Hi, Does that mean I should do this… sayang@DESKTOP-IFS80HM:~$ export PYTHONPATH=/home/sayang/root-6.24.04/bin/thisroot.sh But import error is still coming … Thanks!

No, you really need to call source /home/sayang/root-6.24.04/bin/thisroot.sh as per point 4 of the instructions at /home/sayang/root-6.24.04 . That command sets all required environment variables for that shell session. For the meaning of PYTHONPATH and what generally goes in there, see e.g. python…

I have read the link given by you and also followed a question related to pythonpath in the newbie section [image] How to set PYTHONPATH when I obtain "Import ROOT error . No module found" Newbie See if you have “pyroot” among: root-config --features In principle you shou…

Hi @Sayandeep_Ghosh , You have to make sure that ROOT was built with PyROOT support, i.e. check in the output of root-config --features. If you cannot find pyroot in the output, you should build ROOT specifying: $ cmake -Dpyroot=ON ... After enabling pyroot, as @eguiraud said, thisroot.sh should …

Hi @jalopezg , Thanks a lot for your help. I just realized a huge mistake that I have made… sayang@DESKTOP-IFS80HM:~$ root-config --features cxx14 asimage builtin_afterimage builtin_clang builtin_cling builtin_llvm builtin_lz4 builtin_lzma builtin_nlohmannjson builtin_openui5 builtin_pcre builtin…

Hi @Sayandeep_Ghosh , [image] Sayandeep_Ghosh: I realized that I need to rebuild root from scratch. Does that mean I should reinstall ROOT or there is any other way. Yes, if you installed ROOT building from sources, you need to rebuild (+ install) including PyROOT. To do so, be sure to inclu…

Yes, if you installed ROOT building from sources, you need to rebuild (+ install) including PyROOT. To do so, be sure to include -Dpyroot=ON in the cmake command line, e.g. No , I haven’t build from the sources from github. Is there any way to include python bindings or pyroot root-config --feature…

Hi @Sayandeep_Ghosh , [image] Sayandeep_Ghosh: I actually followed this video to install root which doesn’t include installing pyroot and python What is shown in the video is how to build and install ROOT from sources. Typically, this is for advanced users only (or for some specific cases). …

Python: No module named 'root' ROOT

root-config --has-pyroot # "pyroot" in ROOT 6 was "python" in ROOT 5 BTW. Regardless of the version, the python’s module is named “ROOT”, not “root”.

Python: No module named 'root' ROOT

You MUST use EXACTLY the same Python version (and the same compiler) that your ROOT binaries were built for (otherwise, expect mysterious crashes anywhere, anytime): root-config --python-version # C/C++ calling python ; root-config --python2-version # python 2 calling C/C++ ; root-config --python3-version # python 3 calling C/C++ ; BTW. Remember to “source /the/location/of/ROOT/bin/thisroot.sh” to add your ROOT executables and libraries to your environment (when ROOT is not installed in some “…
