AttributeError: 'Process' object has no attribute 'get_connections'

[Tac Tacelosky]

I'm new to python and to psiturk, and am stuck on what I assume is a python configuration issue.  I'm trying to run this on Ubuntu 12.04.  Any suggestions?

I'm running psutiil 3.1.1

tac@bonobo-1:~$ pip show psutil

Name: psutil

Version: 3.1.1

Location: /usr/local/lib/python2.7/dist-packages

Thanks,

Tac

I had this same problem and just followed the advice from a previous post to downgrade psutil.

This worked for downgrading:
sudo pip uninstall psutil
sudo pip install psutil==2.2.1

there could be a simple pull request to fix this…

I'm still getting this error. I tried

(1) Installing from github, as suggested here, (including over http):
https://github.com/NYUCCL/psiTurk/pull/192

(2) Reverting to an older version of psutil, as suggested in this thread,

but no luck. Anything else I should try?

Hi,
I would like to point out that psiturk is not compatible with Ubuntu15/anaconda2 at the time of writing.
You cannot downgrad psutil with anaconda2 (you will have an error regarding dynamic libraries) and you cannot use the trunk psiturk2.1.0dev as suggested on other post.
The only solution I found is to install psiturk with the classic package python2 and to downgrad psutils.
