Any variant of Jupyter can take different kernels for different chunks in a single notebook?

Any variant of Jupyter can take different kernels for different chunks in a single notebook?

The two multiplexing kernels that I know are "scripts of scripts": http://vatlab.github.io/SOS/#runningsos

and Min's "all the kernels": https://github.com/minrk/allthekernels

BeakerX (still in alpha) intends to have true polyglot kernel as well (https://github.com/twosigma/beakerx), but isn't there yet.

Its predecessor, Beaker Notebook (http://beakernotebook.com/) supports this well.

Hydrogen can run multiple kernels for code blocks inside a markdown file.

See here: https://github.com/nteract/hydrogen/tree/636ccab71a996a0d571f09c5e803c290b9fb919e#multiple-kernels-inside-one-rich-document

Nick:

Thank you very much for your information.

Hydrogen looks very promising but didn't work on my Mac OSX el capitan,  anaconda-based jupyter. 

I followed the hydrogen documentation but didn't figure it out. I also leave create an issue on its github page.

Very appreciated if you can share your experience.

Another option is Jupyter cell magic (%%) for external languages, when the kernel is IPython. This is available for R, Julia, Fortran, Cython, .NET, etc.

Still there is difference when the magic cell executes in subprocess (%%ruby) or by embedding the other language in Python (e.g. R).
