Created attachment 489542 [details] output of emerge --info When trying to create a new Python notebook in Jupyter Notebook, the kernel version will always match the version of Python that was used to launch Jupyter Notebook itself, regardless of what the user requests. For example, if jupyter-notebook is launched with python2.7, both "Python 2" and "Python 3" notebooks will use python2.7. Similarly, if jupyter-notebook is launched with python3.4, both "Python 2" and "Python 3" notebooks will use python3.4. Relevant package versions: dev-python/jupyter-1.0.0-r1 dev-python/jupyter_client-5.1.0 dev-python/jupyter_console-5.1.0 dev-python/jupyter_core-4.3.0 dev-python/ipython-5.4.1 dev-python/ipykernel-4.6.1 dev-python/nbconvert-4.3.0 dev-python/nbformat-4.3.0 dev-python/widgetsnbextension-2.0.0 Steps to reproduce: 1) Install dev-python/jupyter and its dependencies with python2_7 and python3_4 in PYTHON_TARGETS 2) Run the command: EPYTHON="python2.7" jupyter-notebook 3) Create two new notebooks, one that is "Python 2" and one that is "Python 3" 4) In each new notebook, run "import sys; print(sys.version)" 5) Stop jupyter-notebook, and re-run it with: EPYTHON="python3.4" jupyter-notebook 6) Repeat steps 3 and 4 Expected results: Python's version should match what was chosen when the notebook was created Actual results: Python's version matches the version of Python used to execute jupyter-notebook
Hi Eric, thank you very much for the report. Fixed in ipykernel-4.6.1-r2 by https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=0438d76575de86cf88d45a0264214afa87781b53 Please test.
> Please test. Thanks, it's working now. On a related note, please take a look at https://bugs.gentoo.org/show_bug.cgi?id=629376.
This patch breaks things when multiple versions of python3 are installed. When I install python3.5 and python3.6, the python implementation is hard coded to python3.6 and breaks running jupyter notebook with python3.5, causing it to hang. I suggest changing sed -e "s:python:${EPYTHON}:" -i "${ED}"usr/share/jupyter/kernels/${EPYTHON%.*}/kernel.json || die to sed -e "s:python:${EPYTHON%.*}:" -i "${ED}"usr/share/jupyter/kernels/${EPYTHON%.*}/kernel.json || die in the ebuild.
