jupyter-irkernel

问题 I have instaled R in my jupyter through anaconda and It was working fine. Today I found this message when I opened R form Jupyter and I don't know what is the problem ? The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened. I'm using Mac OSX 回答1: I had the same problem in Mac OSX when R

问题 I have a Jupyter notebook (python3) which is a batch job -- it runs three separate python3 notebooks using %run . I want to invoke a fourth Jupyter R-kernel notebook from my batch. Is there a way to execute an external R notebook from a Python notebook in Jupyter / iPython? Current setup: run_all.ipynb : (python3 kernel) %run '1_py3.ipynb' %run '2_py3.ipynb' %run '3_py3.ipynb' %run '4_R.ipynb' The three python3 notebooks run correctly. The R notebook runs correctly when opened separately in

问题 I'm pretty new to the forum, so I'm sorry if this question has already been answered. I looked around, and although I saw that some had similar issues, I couldn't find the solution to my problem on any previous posts. So - here goes...

问题 I have already installed Jupyter notebook in my ubuntu 16.04 machine. In jupyter notebook there is by default python installed. Now I want to use R from jupyter notebook. To do so I followed IRkernel installation link and run below commands: install.packages('devtools') devtools::install_github('IRkernel/IRkernel') But when I run IRkernel::installspec() command it shows below error: jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127 I am now confused

问题 Despite all my efforts, I wasn't able to install the R kernel for my IPython/Jupyter notebook on Canopy. I've closely followed the clear instructions given in: http://www.michaelpacer.com/maths/r-kernel-for-ipython-notebook (or, alternatively, http://irkernel.github.io/installation/) All goes well until the last step that install the kernel on Jupyter: IRkernel::installspec() Here is the weird message I get: File "/Users/julien/Library/Enthought/Canopy_64bit/User/bin/jupyter-kernelspec", line
