[IPython-dev] executing notebooks locally

[Toby Burnett]

I'm using IPython notebooks to document code, in which cell output reflects the machine it was run on. I want to export the notebooks to a different machine, and rerun them to reflect that machine's environment. That is, the equivalent of starting a server, loading each notebook in a browser, then clicking  Cell |Run All.  Obviously it would be more convenient to just run a local script to do this.

There seems to be no such option in the ipython notebook command. But I found this on stackoverflow:
http://stackoverflow.com/questions/19640280/execute-another-ipython-notebook-in-a-separate-namespace

My attempt  to do this is:

from IPython.nbformat import current
ip = get_ipython()
with open('Untitled1.ipynb') as f:
    nb = current.read(f, 'json')
code_cells = filter( lambda x: x.cell_type=='code', nb.worksheets[0].cells)
map(ip.run_cell, code_cells)

But with a result
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

      4     nb = current.read(f, 'json')
      5 code_cells = filter( lambda x: x.cell_type=='code', nb.worksheets[0].cells)

    147             result = self[key]
    148         except KeyError:
--> 149             raise AttributeError(key)
    150         else:
    151             return result

AttributeError: isspace

Indeed the NotebookNode object does not have an isspace function. (This is 2.0-dev.)
Any thoughts?
