So the folks at NUMFocus needed stickers and our current pandas logo was
only an old .png that could be reproduced in
a vectorized graphic format. So they redid the logo to make a vectorized
graphic that would print.

Attached are all of the logo graphics.

Its pretty close to the old one and now comes in stacked/horizontal formats.

Subject: [Pandas-dev] Empty table datasets in HDF5 (pytables)
Message-ID: <CANvpRu8kdZGy02dt7kZvf72JcJnQbxH=-xENZvOFZDVw8dBeeQ@mail.gmail.com>

In 2012, there was this issue:

https://github.com/pydata/pandas/issues/1707

Which was patched:

https://github.com/pydata/pandas/commit/603e5ae9f8c6dc7bd17e86f556c01820c6ffed61

It now appears that this ability has been explicitly disabled, such that
the pytables interface now checks for empty datasets and silently refuses
to create the underlying HDF5 objects.

The offending code is in pandas/io/pytables.py:_write_to_group()

        # we don't want to store a table node at all if are object is 0-len
        # as there are not dtypes
        if getattr(value, 'empty', None) and (format == 'table' or append):
            return


I'm preparing a patch and pull request, but this is such a deliberate step
that I'd like some clarification as to why this is so. Reenabling this
behaviour in our production environment has the expected results with no
obvious downsides.

Can anyone provide a rationale for not introducing the patch/reenabling the
behaviour ?

Thanks in advance,

Damion K. Wilson
