Runtime error with CEO Change Announcements
Kay Raush
edited Nov 26, 2016

Hello all. I'm a newbie playing around with the CEO change announcement pipeline in the algorithms view.

I'm running into the error below where I cannot access any properties of the data source in this mode (research mode is fine).

I found another notebook using the data source, cloned it and tried to run it and it is still failing with the same error (this is the one I cloned) https://www.quantopian.com/posts/ceo-change-plus-sentiment-signal#5762f1a2d48cc61a920001ab

example:

gender = CEOChangeAnnouncements.out_ceogender

There was a runtime error.
AttributeError: type object 'CEOChangeAnnouncements' has no attribute 'out_ceogender'
...

what am I missing? any ideas where I could find documentation on the CEOChangeAnnouncements class? thanks!

Refer to this link for information on how to use the library. The source code in the link you've posted seems outdated as the link I've posted says that you can import the free library sample by doing the following:

from quantopian.interactive.data.eventvestor import ceo_change_free

Hello, thanks for your comment. As far as I understand there are different libraries for the research environment (interactive) and the algorithm environment. When I try to use the import above in the research mode it's fine, but in the algorithm environment it says

*"Runtime exception: ImportError: No module named interactive.data.eventvestor
The interactive namespace is not available in the backtester, but can be used in research. Try importing from quantopian.pipeline.data instead."

but this also fails to import 

from quantopian.pipeline.data.eventvestor import ceo_change_free as cc

as does

from quantopian.pipeline.data.eventvestor import CEOChangeAnnouncementsFree

(really just guessing now).

What is bizarre is I was able to get one bit of information out of the CEOChangeAnnouncements import:

gender = CEOChangeAnnouncements.in_ceogender

but all of the other columns listed in the documentation aren't accessible

I am running into the same issue. Any updates on this?

Hi Linus,

I apologize. I thought that I had responded to this thread yesterday. I've attached a sample notebook that uses a few of the columns from the CEO dataset in pipeline. If you clone the notebook, does it work for you?

Hi Jamie,
The notebook you attached works. However you can only access some columns. For example in_ceogender.latest works but out_ceogender.latest gives an AttributeError.
Anyways thanks for your help.

Has the CEOChange... API disappeared in 2019?
