Need Help for sync my folder psychopy to pavlovia

[Alexander_Bell]

Hi,

I need help I have been desperately trying for 2 days to synchronize my directory C:\PSYCHOPAV\EXP1 containing
my file “EXP1.psyexp” and 3 directories
Stimuli
data
ConfigFiles

When from the Psychopy application I try to synchronize
it asks me to create a new project
I put the name “EXP1”
directory: C:\PSYCHOPAV
I have pavlovia the project but when I go into it in view code. Nothing :-((
just an html page with
the following instructions

it seems so simple on the youtube videos. (Grrrrrr)

thanks for your help
Nazim

It might be that you are trying to sync too much in one go. How big is each folder? Try removing one or more of the sub-folders for the first push, or look here:

oh miracle. Thank you very much for your advice

my folder has been copied
i had to delete a large part of my stimuli (14 MB) it’s weird right?
what do you suggest to put the rest of my stimuli (add them to my folder in several times?)
however now when I want to launch Pilot
i have a 403 Forbidden error
nginx
Do I have to wait a moment or is it another problem?
Best regards

[wakecarter]

Let’s solve the 403 forbidden error first.

What is now in your repository? What are you pressing to give you the error?

[Alexander_Bell]

URL of experiment: EXP_307_V1 [PsychoPy]

Description of the problem:frankly it’s just nonsense pavlovia
only bugs at every step. while it should be either simple or efficient, or properly documented. and to say that you need a license to use…
2 days to do a sync.
when it is done. impossible to launch because error 403 forbidden nginx
i ended up manually moving the html file and now I find myself stuck with a window in initializing mode for 30 min

SERIOUSLY?
even in the 80s with my old ZX81 I was able to make more reliable programs

[wakecarter]

Running locally (as on a ZX81) is much easier than online.

The answer is (almost) never to edit the generated code When you create an experiment in Builder, PsychoPy then generates a Python file which you can use to run the experiment locally and two JavaScript files suitable for running the experiment online (using current and older browsers). If something doesn’t work, there may be a temptation to make edits directly to the Python/JavaScript files rather than the Builder file. However, this is generally a bad idea for two reasons: The process is o…

when à clic on view code i see this
EXP1 : directory (Name of my project)
and hiden file .gitignore
in my EXP1 directory i have theses files
EXP1.psyexp
and EXP1_lastrun.py
so i’ve tried to use File/export HTML
and a sync
but the application generate 2 files
Exp_307_V1 .js and
EXP_307_V1-legacy-browsers.js
( a old name of my project during these 2 days of debbug)
why ?
i tried to rename and change all ref to the old name
without success …

I changed the name in the experiment settings, but still no success.
I also tried to use the web pilot experiment locally, and I also get stuck at http://localhost:12002/ with the initializing status.
My version is V2024.2.4
What can i do now ?
I agree, it would be better to do it locally, but unfortunately I have to share this experience with my group of students.

If you made a change and there was no difference online check this tip.

This is the first in what I hope will be a daily series of tips. The topic has been closed to prevent discussion. For each tip I will add a link to a thread which can be used instead. Run the latest version of your experiment When you synchronise changes to your experiment, you may need to clear your browser cache to see those changes online (using Ctrl-Shift-R, Ctrl-F5, or equivalent). If this does not work (for example because a spreadsheet has changed rather than the JavaScript files or you …

[Alexander_Bell]

I don’t understand. Do I have to type the whole knowledge base?
I don’t think it’s a cache problem since this problem occurs with other browsers and other workstations.
I have a background as a computer scientist for over 20 years and honestly I have rarely seen such a level of bug in a program that is also sold under license. I don’t think my group of psychology students have the resources or the desire to spend so much time on this type of problem.
It’s just nonsense…

Here are the slides I’m using with my second year undergraduates on Thursday.

PsychoPy Primer

While far from perfect, PsychoPy is the most intuitive software I’ve found for running psychology experiments. I started in 1998/1999 with Superlab2 and used to use MATLAB until I came across PsychoPy a little over 10 years ago.

I think you should start with a simpler experiment (at least with fewer resources) and get it running locally before pushing online.

[Alexander_Bell]

thanks,
nevertheless
Similarly I used a lot in another life labview, matlab which for me remains a reference in terms of quality. but also very avant-garde software like AVS (https://avs.com/) and I’m talking about a time that dates back more than 30 years. but I have never been confronted with this bug on software (Pavlovia) sold under license
concerning my experience it is very simple and works very well locally
2 loops with a presentation of images and sound, nothing complicated in theory…

[wakecarter]

I haven’t yet seen any evidence of specific bugs in your code. If you have successfully synced your experiment with Pavlovia then please could you add me as a developer in Gitlab and I’ll see if there’s a simple fix. If you have a working local experiment which doesn’t rely on Python libraries in custom code components then it should be fairly easy to fix

[wakecarter]

The changes I made to get your experiment working were:

1. Changed \ to / in your spreadsheets to solve
   

Wakefield's Daily Tips

Use foreslashes not backslashes in file paths Windows file paths use backslashes (\) to separate the folders in the path. This doesn’t work online because Linux-base servers use slashes (/) instead. Worse than that, the backslash character is used to mark the beginning of an “escape sequence” so the following character is interpreted by JavaScript as something else. Here are some examples: \n new line \t tab \' or \" Literal single or double quotes \\ Literal \ \b backpace \xHH characte…

2. Changed Stimuli to stimuli in sound_1 and sound_2

Wakefield's Daily Tips

Coding is case sensitive Python and JavaScript are both case sensitive languages. The commands you write in code components must be of the correct case, and the cases of the names of your components and variables must match. For example, you could have three distinct variables called item, Item, and ITEM (don’t do this). In addition, when running online you also need to use the correct case for your filenames. Locally you can have item.png in your spreadsheet and your experiment will successful…

3. Removed $random(4) * 200 and $random(4) * 400 from the selected rows fields. I don’t know what they are supposed to do. Locally it seems to produce a list of four random numbers, e.g. [113.92972671 65.91239136 118.54189524 10.72040802]. Online it produces a single random number in that range. Neither make sense for selected rows.
   
   

For now, I’ve replaced it with a code component in each routine which breaks the loop after 4 iterations:

if loopStimul.thisN == 3:
    loopStimul.finished = True

You can try it here. EXP1 [PsychoPy]

Since the loops have a fixed random seed then it plays the say four images eight times. Are your two spreadsheets identical?

This tip tells you about how selected rows works. Either a list of integers or a string of two integers separated by a colon.

Wakefield's Daily Tips

Avoid multiple spreadsheets One way of counterbalancing blocks in an experiment is to have an outer loop which points to a spreadsheet which contains the names of different spreadsheets to use in an inner loop. The main issue with this is that if you have multiple spreadsheets with the same columns and you want to make a change, you have to make it to all of them. The other more minor issue is that you may have to specify the spreadsheets as additional resources in Experiment Settings / Online. …

[Alexander_Bell]

Thank you very much for your help.
interesting to know for the future concerning the sensitive case
for the random, the idea was to do a random pickup of the 4 x 8 images
but different at each run of the experiment to avoid a learning effect
then represented with 30% of new images in the recovery phase

[wakecarter]

If you change the random seed from 4 to the participant number then you will get a different set of 4 for each run.

Begin Experiment

randomSeed = int(expInfo['participant']) # assuming you are using the default random participant number

Alternatively, you could just generate a random integer in Begin Experiment.

randomSeed = randint(1000)
thisExp.addData('seed',randomSeed)

Then add randomSeed to the loops.
