The Notebook has support for multiple programming languages, sharing, and interactive widgets. Fedora Account System Username: tomspur This is the work in procress version of the python-jupyter-notebook as some dependencies need to be reviewed first and will be added to this ticket as dependency.  Thomas Spura 2016-04-18 08:06:15 UTC Should this package be named python-jupyter-notebook or simply python-notebook? On pypi it is also just named notebook: https://pypi.python.org/pypi/notebook  Zbigniew Jędrzejewski-Szmek 2016-04-18 14:20:36 UTC I think python-jupyter-notebook meshes better with python-jupyter-client and python-jupyter-core. Easier to see that those packages go together.  Philippe Makowski 2016-04-18 18:43:20 UTC for info, here how I spitted the package in Mageia, like Debian did) http://svnweb.mageia.org/packages/cauldron/jupyter-notebook/current/SPECS/jupyter-notebook.spec?view=markup doc is not build yet, but should come later. I think that the patch is needed (came from Debian) : http://svnweb.mageia.org/packages/cauldron/ipython/current/SOURCES/0001-use-setuptools-also-for-the-install-target-so-the-py.patch?view=markup  Zbigniew Jędrzejewski-Szmek 2016-04-19 19:53:19 UTC BR: python-sphinx_rtd_theme Links in /bin/ should be updated similarly to python-jupyter-client. %license. Suggestion to use "%global _docdir_fmt %{name}". %description should be word wrapped to 80 columns.

Elliott Sales de Andrade 2016-05-18 09:07:25 UTC This spec depends on python(3)-ipython-genutils, but the package is named python(3)-ipython_genutils.

Links are still reversed.

Still valid. Can you post an updated spec file? It would be great to get this wrapped up some time before F26, leaving enough time for testing.  Miro Hrončok 2017-01-11 15:24:37 UTC I didn't have time to examine this closely, but a quick question: What's the benefit of having both python2 and python3 notebooks? Isn't it possible to just have the Python 3 version and install the Python 2 kernel to use it inside? (I really don't know) If the above is true but the notebook module is to be imported form other packages, then keep the package split, but just include the executable in the Python 3 subpackage. Guidelines: If the executables provide the same functionality independent of whether they are run on top of Python 2 or Python 3, then only the Python 3 version of the executable should be packaged. Transitioning from python2 to python3 is left to individual package maintainers except for packages in Fedora's critical path. For these, we want to port to python3 versions in the same Fedora release if possible.

I would welcome (co-)maintainers as I find increasingly less time to work on this, but want to have ipython updated in Fedora... I would remove the -doc package altogether as it uses intersphinx during the build. %changelog - rename to python-notebook - only ship python3 executables - update to 4.4.1 Spec URL: https://tomspur.fedorapeople.org/review/python-jupyter-notebook/python-notebook.spec SRPM URL: https://tomspur.fedorapeople.org/review/python-jupyter-notebook/python-notebook-4.4.1-1.fc25.src.rpm  Zbigniew Jędrzejewski-Szmek 2017-02-13 16:39:46 UTC Links give 404.

In that case, I think the mv + ln section in %install is not necessary and providing only the unversioned executables is enough. More importantly, running %py2_install after %py3_install is overwriting the executables with the py2 version. $LANG=C.utf-8 rpm -qlvp python3-notebook-4.4.1-1.fc26.noarch.rpm | grep bin -rwxr-xr-x 1 root root 101 Feb 14 01:01 /usr/bin/jupyter-nbextension lrwxrwxrwx 1 root root 23 Feb 14 01:01 /usr/bin/jupyter-nbextension-3 -> jupyter-nbextension-3.6 -rwxr-xr-x 1 root root 101 Feb 14 01:01 /usr/bin/jupyter-nbextension-3.6 -rwxr-xr-x 1 root root 100 Feb 14 01:01 /usr/bin/jupyter-notebook lrwxrwxrwx 1 root root 20 Feb 14 01:01 /usr/bin/jupyter-notebook-3 -> jupyter-notebook-3.6 -rwxr-xr-x 1 root root 100 Feb 14 01:01 /usr/bin/jupyter-notebook-3.6 -rwxr-xr-x 1 root root 105 Feb 14 01:01 /usr/bin/jupyter-serverextension lrwxrwxrwx 1 root root 27 Feb 14 01:01 /usr/bin/jupyter-serverextension-3 -> jupyter-serverextension-3.6 -rwxr-xr-x 1 root root 105 Feb 14 01:01 /usr/bin/jupyter-serverextension-3.6$ rpm -qp --requires python3-notebook-4.4.1-1.fc26.noarch.rpm | grep bin /usr/bin/python2 /usr/bin/python3 \$ head -n1 usr/bin/jupyter-notebook #!/usr/bin/python2 -s  Miro Hrončok 2017-02-21 13:31:08 UTC I'm taking over here as agreed with Thomas, as he lacks time to do it.

Also, I've tried run the tests and so far i'm failing. There's a missing dependency that we'll package soon, but the test suite cannot locate the python and python3 kernels. I'd appreciate help here. The tests are there, commented out.  Zbigniew Jędrzejewski-Szmek 2017-02-22 02:12:41 UTC %description -n python3-%{pypi_name} should also use %_description. I'm not quite convinced about the drop of python2 executables. But they can always be added back, so let's continue on the presumption that python2 and python3 executables are interchangeable. Provides: bundled(jquery) Provides: bundled(jquery-ui) Provides: bundled(jquery-typeahead) Provides: bundled(mathjax) + a bunch of other js stuff. I don't know if it's worthwhile to unbundle those. Maybe mathjax? Some fonts could be unbundled easily: Requires: fontawesome-fonts Requires: fontawesome-fonts-web ln -vfs /usr/share/fonts/fontawesome/fontawesome-webfont.woff %{python3_sitepackages}/notebook/static/components/font-awesome/fonts/fontawesome-webfont.woff etc. loading intersphinx inventory from http://ipython.org/ipython-doc/dev/objects.inv... loading intersphinx inventory from https://nbconvert.readthedocs.io/en/latest/objects.inv... loading intersphinx inventory from https://nbformat.readthedocs.io/en/latest/objects.inv... loading intersphinx inventory from https://jupyter.readthedocs.io/en/latest/objects.inv... → those will fail in koji. It might be worth putting those objects.inv files in sources and installing them into the cache for the build. But that's a minor thing, can be fixed up once the package is in. Looks good otherwise. I'll finish the review when the tornado dep is available.  Zbigniew Jędrzejewski-Szmek 2017-03-05 22:11:00 UTC python-terminado is in QA state. Miro, are you planning an update?  Miro Hrončok 2017-03-05 22:32:48 UTC Yes, I am, but I was kept busy with the testable deadline for Fedora Changes. Will look at this sometimes during the week.  Miro Hrončok 2017-03-07 19:55:41 UTC I believe that the tests does not see the python2 and python3 kernels, because those kernels first need to get installed with: pythonX -m ipykernel install (Where X is 2 and 3.) This command shall create a directory with kernel.json in it. I believe that python-ipykernel package shall create those directories and install them to /usr/share/jupyter/kernels in order to make them discoverable for our tests here and maybe also for installed python-notebook. Another problem is that the above command will fail with our python-ipykernel with: ImportError: No module named 'IPython.paths' as our ipython is old and does not have the paths submodule yet. I was able to generate the file from a virtualenv and it looks like this: { "argv": [ "/home/churchyard/tmp/venv36/bin/python", "-m", "ipykernel", "-f", "{connection_file}" ], "display_name": "Python 3", "language": "python" } I will try to modify the python-ipykernel package to install similar files for /usr/bin/python2 and /usr/bin/python3 and see if it solves the problem. See https://ipython.readthedocs.io/en/latest/install/kernel_install.html#kernels-for-python-2-and-3  Miro Hrončok 2017-03-07 20:21:41 UTC Ok, taht fixes the problem but the tests here are throwing a lots of: ModuleNotFoundError: No module named 'IPython.paths' So i guess we need newer ipython anyway.  Miro Hrončok 2017-03-08 08:48:12 UTC Idea: Backport IPython.paths.get_ipython_dir() for now to speed things up.  Miro Hrončok 2017-03-08 09:19:48 UTC That brings us to: Traceback (most recent call last): File "/usr/lib64/python3.6/runpy.py", line 193, in _run_module_as_main "__main__", mod_spec) File "/usr/lib64/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals) File "/usr/lib/python3.6/site-packages/ipykernel/__main__.py", line 2, in from ipykernel import kernelapp as app File "/usr/lib/python3.6/site-packages/ipykernel/kernelapp.py", line 100, in ConnectionFileMixin): TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases That's an ipykernel class inheriting from an ipython class. So as i thought: our ipykernel does not work without newer ipython.  Miro Hrončok 2017-03-08 11:28:05 UTC Meanwhile, I looked at the bundling: Spec URL: https://churchyard.fedorapeople.org/SRPMS/python-notebook.spec SRPM URL: https://churchyard.fedorapeople.org/SRPMS/python-notebook-4.4.1-2.fc25.src.rpm Ended up with: Requires: fontawesome-fonts Requires: fontawesome-fonts-web Requires: mathjax >= 2.4 Requires: js-backbone >= 1.2 Requires: js-marked >= 0.3 Requires: js-moment >= 2.8 Requires: js-underscore >= 1.5 # Versions from bower.json Provides: bundled(bootstrap) = 3.3 Provides: bundled(bootstrap-tour) = 0.9.0 Provides: bundled(codemirror) = 5.22.2 Provides: bundled(es6-promise) = 1.0 Provides: bundled(google-caja) = 5669 Provides: bundled(jquery) = 2.0 Provides: bundled(jquery-typeahead) = 2.0.0 Provides: bundled(jquery-ui) = 1.10 Provides: bundled(requirejs) = 2.1 Provides: bundled(text-encoding) = 0.1 Provides: bundled(xterm.js) = 2.1.0  Miro Hrončok 2017-03-14 12:56:23 UTC With bz1426799 and bz1430093 the tests pass!
