StringIO and 'neptune.send_artifact' about neptune-client HOT 1 CLOSED

Hi Ben

Thank you for your kind words about Neptune.

I've been checking your issue and found out that despite the fact that you provided some content to the StringIO, Neptune could read only empty content. Traceback is related to the issue of wrong handling empty StringIO and we've just publish a fix release 0.4.127. It should be available to download very soon.

More interesting for you will be fixing the stream, so Neptune will be able to read it's content. In this fix I also updated the docs for log_artifact method(). According to the docs, when you write to some stream like StringIO, it's position is set to the end of the steam. When you now call read() on this stream, you won't get any content. You need to rewind the stream to the beginning (by calling seek(0) for example), so anyone (and Neptune) can read it.

Hope it will resolve your issue. Good luck with Neptune.

Kind regards,
Szymon
