[IPython-dev] Removing "Out[]" prompts in nbconvert PDF output

[Maximilian Albert]

Hi Aaron,

Thanks a lot for your suggestion! This is actually exactly what I tried
before sending my email to the list, and it does indeed work in certain
cases, but some of my notebooks didn't convert correctly with it. I've put
up a minimal example here:

   https://github.com/maxalbert/nbconvert-templating-issue

If you type "make" it will use different templates to generate three pdf
documents from the notebook "minimal_example.ipynb" (more information on
what the templates do is in the README of the repo). You will see that for
the cell containing the image with the musical note, the "Out[]" prompt is
retained. The notebook "sample_notebook.ipynb" has a slightly longer
example, comparing with some other types of output cells for which the
"Out[]" prompt is indeed removed.

I won't have time to dig into this before the weekend, and my jinja-fu is
almost zero, so if anyone has a quick idea what's going on here I'd
appreciate it.

Many thanks!
Max
