provide proper nltk.tree png output / backport nltk.tree._repr_png()
arne-cl opened this issue · comments
hilda.py already provides an option to show a drawing of the resulting tree,
but since it relies on an old version of nltk (2.0.1rc3; newer versions won't work),
we can't call _repr_png() on the tree to save it to a file.
I don't need this any longer.
