Ignore `:exports none` about ox-ipynb

[AndreasMatthias]

Seems like ox-ipynb.el#L842-L858 should handle this, but it doesn't work for me.

By accident I mistyped the header and then the following worked. Note the doubling of :exports:

#+begin_src jupyter-python :exports :exports none
import numpy as np
#+end_src

I am not sure how you can have it both ways. Your work around seems to work like you want, presumably because you get something like ":export none" as the string, so the code you linked above doesn't get rid of it, but for some reason still works to exclude it in LaTeX. I guess if I did it correctly in ipynb, it would exclude it there too.

One solution you could use is a function in ox-ipynb-preprocess-hook that removes ":export none" from source blocks.

Thanks for the hint to ox-ipynb-preprocess-hook. I don't know much about the code base of org-babel but I'll give it a try.
