ImportError: Unable to load OpenGL library
Computer: MacOS Monterey Python Version: 3.7.11 Jupyter Notebook Version: 6.3.0 Brain Interface Used: Cyton+Daisy
I am trying to Test if the Python library installed correctly by using the code:
from eegnb import generate_save_fn from eegnb.devices.eeg import EEG from eegnb.experiments.visual_n170 import n170
I get the following ImportError. Any advice on how to fix this?
ImportError: ('Unable to load OpenGL library', "dlopen(OpenGL, 0x000A): tried: '/opt/anaconda3/envs/eeg-notebooks/lib/OpenGL' (no such file), '/opt/anaconda3/envs/eeg-notebooks/lib/OpenGL' (no such file), '/opt/anaconda3/envs/eeg-notebooks/lib/python3.7/lib-dynload/../../OpenGL' (no such file), '/opt/anaconda3/envs/eeg-notebooks/lib/OpenGL' (no such file), '/opt/anaconda3/envs/eeg-notebooks/bin/../lib/OpenGL' (no such file), 'OpenGL' (no such file), '/usr/local/lib/OpenGL' (no such file), '/usr/lib/OpenGL' (no such file), '/Users/priyanshiporwal/eeg-notebooks/OpenGL' (no such file), '/usr/local/lib/OpenGL' (no such file), '/usr/lib/OpenGL' (no such file)", 'OpenGL', None)
Same here, I've been getting the same issue, with the exact same specs as @porwal97. Note: I use an ARM MacBook Air. I've read the main SO article for this error (https://stackoverflow.com/questions/63475461/unable-to-import-opengl-gl-in-python-on-macos) and followed the recommended answer. I've tried changing it to my actual path in my own file system, but nothing.
Hi @porwal97 @Zaduk .
Thanks for the feedback and your interest in eeg-notebooks
.
I will try to look into this problem, but unfortunately don't have access to an ARM Mac system for testing.
All of the OpenGL functionality in eeg-notebooks
is 'indirect', i.e. it is via Psychopy
. I don't see the full stack trace from @porwal97 's Import Error, but I would guess it is a from psychopy import visual, core
line. The best help you can get on that issue will be from the Psychopy
forum. I recommend post on there the incriminating Psychopy
line, plus your OS information.
Definitely keep us posted here on how this goes!
I had the same issue in CI: https://github.com/NeuroTechX/eeg-notebooks/runs/5690930290
I updated PsychoPy to the latest version in https://github.com/NeuroTechX/eeg-notebooks/pull/167, which solved the issue.
Note however that:
- In its place there's a new issue, but there's a known workaround: https://github.com/bambocher/pocketsphinx-python/issues/28
- You now also need Python >=3.8
Commenting here to say that I also have issues with OpenGL on a recent (M1) MacBook Air, I assume it is for similar reasons. So if instructions materialize on how to get it working on this type of machine, I would love to see them.
Update: I installed Xcode and it solved the issue for me. I've won, but at what cost...
