Hello!
I installed ROOT from source exactly as indicated in ROOT install. It is installed in /usr/local/ inside the new folder root_install.
I can successfully run ROOT in the terminal using root and can work there.
I also installed python with Anaconda:
$ python --version
Python 3.7.6
The problem is the following: I can import the ROOT package in Python in terminal
$ python
Python 3.7.6 (default, Jan 8 2020, 13:42:34)
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ROOT
>>>
and also in any text editor (Sublime Text 3 for example), but I cannot import ROOT in Jupyter Notebook:

ImportError: dlopen(/usr/local/root_install/lib/libJupyROOT3_7.so, 2): Library not loaded: @rpath/Python3.framework/Versions/3.7/Python3
Referenced from: /usr/local/root_install/lib/libJupyROOT3_7.so
Reason: image not found
I also tried with root --notebook and importing ROOT with the Python3 kernel, but the same error appears.
I tried for a solution following this answer (changing ldd to otool -L for MacOS, and chaging libPyROOT.so to libJupyROOT3_7.so, even though I don’t know if that makes sense):
$ otool -L libJupyROOT3_7.so | grep python
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump: error: 'libJupyROOT3_7.so': No such file or directory
I have also searched for the file libJupyROOT3_7.so inside /usr/local/root_install/lib/ and it is there.
5 days ago I tried installing ROOT with Homebrew but then I couldn’t even import ROOT succesfully in terminal with Python.
I am very new with all these things so if you can help me it would be very much appreciated.
Thank you very much.
