nbsampler not recognising ipython notebook

[philastrophist]

I'm working with the current master branch of pymc3 and I'm trying to use the nbsample in my jupyter notebook.
I've installed ipywidgets with conda install -c conda-forge ipywidgets and called the nbsample with:

with model:
    trace = nbsample(2000, step, start=start) # draw 2000 posterior samples using NUTS sampling

it raises the following:

---------------------------------------------------------------------------
NotImplementedError                       Traceback (most recent call last)
<ipython-input-6-5a8793f1d005> in <module>()
      1 with model:
----> 2     trace = nbsample(2000, step, start=start) # draw 2000 posterior samples using NUTS sampling

e:\git_pkgs\pymc3-dev\pymc3\interactive_sampling.pyc in nbsample(draws, step, start, trace, chain, tune, model, random_seed)
     78             assert(hasattr(IPython.get_ipython(), 'comm_manager'))
     79         except (AssertionError, NameError, KeyError) as e:
---> 80             raise NotImplementedError(_no_notebook_error_message)
     81 
     82         display.display_html(_javascript, raw=True)

NotImplementedError: nbsample can only be run inside IPython Notebook.

it seems that the assertion assert(hasattr(interactive_sampling.IPython.get_ipython(), 'comm_manager')) fails.

To be honest, I had forgotten about nbsample. Given that it has no tests, we should probably remove it. I recommend just using sample.
