JupyterHub and CERN ROOT, Python3 MAC-OSX: root_numpy issue

JupyterHub

I have successfully installed JupyterHub with CERN ROOT, Python3 on MAC-OSX but I’am in trouble with the installation of root_numpy package, perfectly working in Jupyter notebook (on the same machine) and but giving the following error on JupyterHub:

ImportError Traceback (most recent call last)

any help?

by the way my tread to successfully install all the package was

Do you have any environment variables set, e.g. PYTHONPATH, or DYLD_LIBRARY_PATH? Check out the output of:

env | sort | grep PATH

It’s possible that you have set an environment variable in your profile that’s required for this to work, that doesn’t end up inherited by the JupyterHub environment.

yes, I have! this is the output of my PATH environment
CMAKE_PREFIX_PATH=/usr/local/root

JUPYTER_PATH=/usr/local/root/etc/notebook

LIBPATH=/usr/local/root/lib

MANPATH=/usr/local/root/man:/usr/local/share/man:/usr/share/man:/opt/X11/share/man:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/share/man:/Applications/Xcode.app/Contents/Developer/usr/share/man:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/share/man

PYTHONPATH=/usr/local/root/lib

SHLIB_PATH=/usr/local/root/lib

PYTHONPATH is not inherited by jupyterhub subprocesses. You may want to add

c.Spawner.environment['PYTHONPATH'] = '/usr/local/root/lib'

to your jupyterhub_config.py

Thanks Minrk, looks that directive actually is c.Spawner.environment ={ ‘PYTHONPATH’ : ‘/usr/local/root/lib’} but is still giving me error
