Does PsychoPy3 only function with an internet connection?

Coding

Hello everyone,

I’m using stanalone PsychoPy v3.0.2. My computer is not connected to the internet while the study runs. When I try to open the app when not online, the app is closed again after the tipps window shows up. Only on the second or third try to open the app does the app stay open and shows the error below.
Has PsychoPy changed from 2.7 to 3 so that it now always requires an internet connection, or can I change something in my preferences to not search for a connection?

Ah, not deliberate. I can certainly imagine what the problem is though and should be fine to fix quickly. Thanks for the full and informative error report.

@LukasPsy We use PsychoPy3 on standalone machines w/o a problem. We installed it using a conda environment, so maybe there’s a difference there? I’m using a slight modification of environment-3.6.yml on the GitHub site.

Thank you @tjwilli58 for the advice.
I won’t switch to a conda enviroment for this study, but I might in the future. :+1:

Ok, yes. I confrimed that problem and fixed it in https://github.com/psychopy/psychopy/pull/2256/commits/acd27c759f1613b7c398e4bd5d7231c444eb7671

That will be included in 3.0.4 bugdfix release (v soon).

I think the conda package is misleading - I think it should probably fail there too if using 3.0.2. My guess is that tjwilli58 is using one of the PsychoPy3 beta versions (which didn’t have this buglet).

@jon, That’s correct. We’re currently using 3.0.0b12.
I’m glad to see that this bug has been found and fixed before we upgraded to the latest version. We definitely need PsychoPy to work offline!

@jon, I hope this is the correct thread for posting my issue… I should also say that I’m a psychopy newbie. My psychopy3 experiment wont launch due to the following error message in my output:

Welcome to PsychoPy3!
v3.2.3
Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\stdOutRich.py”, line 157, in onURL
self.parent.onURL(evt) # just pass this one on
AttributeError: ‘NoneType’ object has no attribute ‘onURL’

Then there is also this message:

pygame 1.9.4
Hello fomr the pygame community. http://www.pygame.org/contribute.html
28.9116 WARNING Couldn’t connect to psychopy.org

Is this a proxy issue? I should also say that I am sitting behind my institutes proxy and firewall…

Is there anything that can be done?

Thanks!
