Issue using anaconda to run an older version of python for Tobii experiment

MDJ

Hi all,

I had an experiment in which I wanted to record eye movements with a Tobii eye tracker. To do this, I followed this page (https://osdoc.cogsci.nl/4.0/manual/eyetracking/tobii/) to download OpenSesame through Anaconda using an older version of Python.

This worked well on my older laptop (I did this about 6 or 7 months ago). However, I am trying to do this on a new laptop as that other laptop is very slow. I have installed Anaconda and I believe I have followed the same steps but now when I enter the following into Anaconda prompt (running as administrator):

conda activate opensesame-py3
opensesame

I get the response: 'opensesame is not recognised as an internal or external command, operable program or batch file'. It seems to have installed the opensesame environment correctly and even allowed me to use pip to install the tobii package. But I can't get past this issue and it won't run opensesame.

I don't know if Anaconda has recently updated or if I have done something differently, but does anyone have any pointers? Apologies if this is a simple question/issue I don't have much experience using Anaconda!

Cheers

Matthew

Hi there,

A little update. I managed to get OpenSesame to run. For anyone else who may be doing the same as me, you need to also follow these instructions (https://osdoc.cogsci.nl/4.0/download/) in order to download appropriate packages. Using anaconda I also installed and ran the following code:

conda config --add channels conda-forge --add channels cogsci
conda install opensesame opensesame-extension-osweb opensesame-extension-updater opensesame-plugin-psychopy rapunzel pygaze qtconsole pyqtwebengine wxpython
pip install soundfile pygame http://files.cogsci.nl/expyriment-0.10.0+opensesame2-py3-none-any.whl
pip install psychopy psychopy-sounddevice

# I also installed:
pip install opensesame-plugin-media-player-mpy

Now when I run

conda activate opensesame-py3
opensesame

in the anaconda prompt it runs Opensesame as expected which is great. However, I now have another issue when I try to run my experiment:

I have noticed someone else here looks to have a similar problem (https://forum.cogsci.nl/discussion/9299/arguments-did-not-match-any-overloaded-call). Would anyone be able to figure out why this is happening?
