While all is fine in Fedora and all packages needed to run the JupyROOT
|
|
|
69d6612 |
notebook are available there, this is not true for EPEL.
|
|
|

|
|

Hopefully the ipython/jupyter stack will at some point be available in
|
|
|
69d6612 |
EPEL too, but at this point in time it is not.

However, it is possible to work around this issue using a python
|
|
|
69d6612 |
virtual environment.
|
|
|
69d6612 |
|
|
|
69d6612 |
First, install the required root packages (as root):
|
|
|
69d6612 |
|
|
|
69d6612 |
$ yum install root root-notebook python3-jupyroot
|
|
|
69d6612 |
|
|
|
69d6612 |
Then return to your non-root user and create a python3 virtual
|
|
|
69d6612 |
environment:
|
|
|
69d6612 |
|
|
|
69d6612 |
$ python3 -m venv ~/jupyter-env
|
|
|
69d6612 |
|
|
|
69d6612 |
Activate the environment:
|
|
|
69d6612 |
|
|
|
69d6612 |
$ . ~/jupyter-env/bin/activate
|
|
|
69d6612 |
|
|
|
69d6612 |
Then install the missing packages in the virtual environment using pip:
|
|
|
69d6612 |
|
|
|
69d6612 |
$ pip install notebook metakernel
|
|
|
69d6612 |
|
|
|
69d6612 |
Then start the root notebook:
|
|
|
69d6612 |
|
|
|
69d6612 |
$ PYTHONPATH=~/jupyter-env/lib/python3.6/site-packages root --notebook
|
|
|
69d6612 |
|
|
|
69d6612 |
And that is it.
|
|
|
69d6612 |
|
|
|
69d6612 |
If you want to start it again and you haven't removed the virtual
|
|
|
69d6612 |
environment, only two of the steps are necessary:
|
|
|
69d6612 |
|
|
|
69d6612 |
$ . ~/jupyter-env/bin/activate
|
|
|
69d6612 |
$ PYTHONPATH=~/jupyter-env/lib/python3.6/site-packages root --notebook
|
