Hello from the pygame community. Contribute - pygame wiki

Experiment ended.

this is what is stated in the runner ‘stdout’. I just have an issue with making the experiment run past the ‘practice trial’. Any help would be much appreciated
Thank you.

re: the Runner output
FYI, those are normal warnings about a mismatch between requested and actual screen size and shouldn’t affect the actual execution of the code!

re: describing your issue
I don’t think your description of your error is thorough enough for your readers to understand what’s going on without making a bunch of assumptions. You should include as much info as possible (that is relevant and organized) to orient the audience. Some examples of good additional info:

  • What task are you trying to implement?
  • What do you mean that it can’t run past the ‘practice trial’? Does it run previous components and then completely crash? In other words, give a thorough description of the circumstances under which the error occurred.
  • What have you tried so far to debug? What are some related forum posts on this Discourse website?
  • What version of Python/PsychoPy are you using, what operating system and version? Are you using Pavlovia?

throwaway opinion on your issue
It seems like a permission issue that could crop up when you try to write a file to somewhere on your computer that you don’t have access to, or maybe something finnicky popping up due to an administrator install of the program.
