Help installing Pyxid module into Open Sesame v3.3

  Hi @MikeN ,

  I don't have experience with the pyxid library myself, but my understanding is that it is indeed only compatible with Python 2. So you would have to use the Python-2-based package of OpenSesame to use it. Alternatively (and again if my understanding is correct), the pyxid2 package should be compatible with Python 3, and might therefore be a better option.

  Cheers!

  Thanks @sebastiaan ,

  Since pyxid2 wasn't available via Anaconda.org I installed pyxid2 using PIP but when I run the OpenSesame program which has an inline script

  import pyxid2

  it returns error message

  exception message: No module named 'pyxid2'

  I used the command pip freeze to check installed packages and it returned

  pyxid2==1.0.1

  So that suggests the pyxid2 module is installed?

  Hi @MikeN,

  Did you install the package into a Python installation on your computer, or into the Python installation that comes with OpenSesame? If you're not on Linux, there is a difference between the two.

  To install directly within OpenSesame, run the following in the Debug Window:

  import pip

  pip.main(["install", "pyxid2"])

  That should install it within OpenSesame's version, I think.

  Hi @Edwin,

  I originally installed it into both but still got the error message about pyxid2 not being installed.

  I followed your suggestion and it seemed to complete the pyxid2 install but gave a permission error about an OpenSesame sub directory. I ran OpenSesame again but this time using "Run as Administrator" first. Re-running the pip install worked fine and the inline script was able to identify the Cedrus Stimtracker as being installed.

  many thanks to both yourself and @sebastiaan! 😀

  Mike.

  Hi Mike,

  Care to point me out to the inline script you used for making pyxid2run with OS?

  Once I knew pyxid2 was installed I used the following script to check if Open Sesame could detect the stimtracker device. The print command wasn't really needed I just included it to make sure the stimtracker was detected.

  
  

  import pyxid2
  # get a list of all attached XID devices
  devices = pyxid2.get_xid_devices()
  
  # assign first device to variable dev
  dev = devices[0]  
  
   # print name of first device to verify detection
  print(dev)
  
  dev.reset_base_timer()
  dev.reset_rt_timer()
  

  
  

  I haven't progressed much further since then so that's all the help I can offer I'm afraid. For more info on the commands check out the Cedrus support page : https://cedrus.com/support/xid/commands.htm

  Thanks Mike!

  
  

  I decided to ask a clleague that's more knowledgeable than myself to dig into the Python code. Will see if they can manage.
