Currently, there is no such feature included in the IPython notebook. Nevertheless, there are some possibilities to make your life easier, like:
use the
%store
or maybe better the%%cache
magic (extension) to store the results of these intermittently cells, so they don't have to be recomputed (see https://github.com/rossant/ipycache)add a
if==0:
before the cells you don't want to executeconvert these cells to raw cells (but you will loose the already stored output!)
(see discussion at https://github.com/ipython/ipython/issues/2125)
