psychopy.app localization error on startup

[Hrvoje Stojic]

Hi all,

I reinstalled my OS and psychopy recently and now I tried running an experiment in Psychopy and I get the following error on either running psychopy directly from terminal or trying to run experiment file with python

Traceback (most recent call last):

  File "/usr/bin/psychopy", line 48, in <module>

    app = PsychoPyApp(0, showSplash=showSplash)

  File "/usr/lib/pymodules/python2.7/psychopy/app/_psychopyApp.py", line 76, in __init__

    self.onInit(**kwargs)

  File "/usr/lib/pymodules/python2.7/psychopy/app/_psychopyApp.py", line 90, in onInit

    from psychopy.app import localization  # needed by splash screen

ImportError: cannot import name localization

it seems there is something off with my locale settings, I tried installing some new locales but it didnt help, I am googling already for few hours trying to figure out what is going on, can anyone shed some light?

psychopy version: 1.81.03

output from locale command:

LC_CTYPE="en_US.UTF-8"

Hi Hrvoje,

That line of code should work ("from psychopy.app import localization"), or at least should not give that error message when starting PsychoPy. Not sure what could have happened, but you might try removing then reinstalling PsychoPy for a second time.

If you run an experiment file from python, doing so should not start PsychoPy (the application). So I am confused about your meaning when you say you get the error when trying to run an experiment file with python.

Also, if you load that same experiment in the Coder view and run it from there, does that work? If not, what error message?

If you open PsychoPy, and in the preferences set the locale to English or Spanish, does that help at all? I am guessing that you can't start the app at all, so won't be able to change the preferences this way.

Hi Jeremy,

thanks for the interest. I tried reinstalling Psychopy but it didn't help, same error message appears.

The error appears if I try starting the psychopy from the terminal:

$ psychopy

or if I tr to start my experiment file mainScript.py from terminal, although here the Traceback is slightly different:

$ python mainScript.py

Traceback (most recent call last):

  File "mainScript.py", line 12, in <module>

    from psychopy import visual, core, gui, event, data

  File "/usr/lib/pymodules/python2.7/psychopy/gui.py", line 11, in <module>

    from psychopy.app import localization

ImportError: cannot import name localization

Trying to start psychopy from the GUI doesn't work at all, i.e. I cannot get to the coder/builder view or to set the preferences from psychopy app.

I also took a look at the dependencies, and only thing that seemed a bit different is that I also have wx version 3.0 installed in my python.

On my old ubuntu distro everything worked without issues, this occurred after I installed newest version (L)Ubuntu 15.04.

Hi,
I have the same problem on a RaspberryPi 2 with raspian (Debian) and psychopy 1.82.01.
An old version of PsychoPy 1.73 GUI did run but experiments did not start. Then I updated to 1.82.01 and now neither experiments nor the GUI will start.
All end up with the same localization import error as reportet bei Hrvoje Stojic.
Anything new on this issue?
Thanks,
Torsten

Hi again,
The problem is somehow related to the wx - localization stuff.
If I remove all _translate() commands, then ... okay I do not know whether it works but the error message moves on to the next file with a _translate() command.

Is there something related to python-wx... that needs to be installed to make the localization work that is not installed automatically?
Thanks,
Torsten
