Expyriment 0.11.dev1: missing png files and #214
Comments
|
Thanks a lot for the feedback.
Please note, the ".dev" versions on the master branch might be broken. They
are not tested and might not work.
We are about to switch to flit for the packaging to simplify our release
process. We want to have much shorter release cycles.
If you need to install the dev-version of the master branch, you should
call "flit install" from the repository directory. I think, the current
master branch should work with flit.

Greetings,
Oliver

… Hello,
- Seing that there were recent commits, I tried a
pip install git+https://github.com/expyriment/expyriment.git
in an environment with python 3.12.0 (installed with pyenv, under Ubuntu
22.04)
This succeeded:
Successfully installed expyriment-0.0.0 pygame-2.5.2 pyopengl-3.1.6
(note the tiny issue with the version number of expyriment;
When I import expyriment in ipython, the version displayed is 0.11.dev1.)
- A first small issue:
expyriment -T crashed because of missing xpy_icon.png
File "/home/cp983411/.pyenv/versions/3.12.0/envs/expyriment2/lib/python3.12/site-packages/expyriment/io/_screen.py", line 107, in __init__
icon = pygame.image.load(os.path.join(os.path.split(__file__)[0],
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: No such file or directory: '/home/cp983411/.pyenv/versions/3.12.0/envs/expyriment2/lib/python3.12/site-packages/expyriment/io/../xpy_icon.png'.
I needed to manually copy there the file xpy_icon.png, as well as
expyriment_logo.png
- ANother issue that your module seems to require numpy but it is not
in the dependencies:
Unable to import OpenGL.arrays.numpymodule.NumpyHandler: No numpy module present: No module named 'numpy'
(this disappeared after a pip install numpy)
- Yet when I try to launch a script experiment, it crashes:

Hi, |
|
Yes, we war planning to release a stable version in the next week. We'll keep you posted. |
|
Great, I'm already looking forward to it. |
|
Good news, I got the master branch version running on my M2 (Python 3.11.7, mamba) by first installing pygame following the pygame MacCompile instructions, installing expyriment via pip install git and finally adding the two missing .png files. |
|
@visserle Compiling pygame should not be necessary, as there are wheels available on Pypi. Is this not the case for ARM64-macs? |
just checked, there is a wheel available! Do you get an error when just installing with PIP? |
|
Now everything is working fine and I can't reproduce the error from my original post. In the meantime, I tried to install expyriment 0.10 with python 3.8 and pygame 1.9.6, which failed on my machine due to a missing SDL.h. I then installed the "MacCompile" which added SDL modules via homebrew, but this didn't fix the error. I then tried to install the dev version of expyriment with pygame > 2.0 a second time - it suddenly worked and the error from my very first attempt no longer occurred. |
|
Expyriment 0.10.0 is only compatible with Python <=3.7. |
|
To clarify, the missing SDL.h error occured when pip install pygame==1.9.6. This might not be related to expyriment. (Also in #211 you reported using expyriment 0.10 with python 3.8.) |
|
Yes, the error occurs because there are not Pygame 1.9.6 wheels on Pypi for that Python version. It hence then tries to build Pygame, but fails, probably because you don't have the needed header files for SDL. We do not recommend to build Pygame from source and hence state that Expyriment 0.10.0 is only compatible with Python<=3.7 (i.e. Python versions for which wheels are available). My response in #211 seems to be a typo (or maybe I used a development version of Expyriment, since nothing was changed since 0.10.0 with respect to stimulus scaling). |
|
Good to know. I'm excited that I can now work with Expyriment on my machine! |
