Expyriment

Using the system's python3 (recommended)

pip install numpy pyopengl pygame future mediadecoder pyserial pyparallel swig
pip install expyriment[all]

With Anaconda Python

Download and install Anaconda Python

LATEST_ANACONDA=Anaconda3-2022.05-Linux-x86_64.sh
wget https://repo.anaconda.com/archive/${LATEST_ANACONDA}
chmod +x ${LATEST_ANACONDA}
./Anaconda3-2022.05-Linux-x86_64.sh 
conda update -n base -c defaults conda

Expyriment environment

conda create -n expyriment python=3.8
conda activate expyriment
conda install ipython numpy pyopengl
pip install mediadecoder
pip install sounddevice
pip install expyriment[all]

If pip install experiment[all] fails (typically because of problems while trying to compile pygame1.9.6), try:
mkdir ~/git
cd ~/git
git clone https://github.com/expyriment/expyriment.git
cd expyriment/
pip install .

Checking expyriment

conda activate expyriment # only if you used anaconda installation 
expyriment -T

Setup blocking on vertical synchro for AMD RADEON gpu

cd ~/git/PCBS/experiments/expyriment
python tearing-test.py
sudo apt install xvattr
echo "export vblank_mode=3" > /etc/profile.d/radeon.sh
cd ~/git/PCBS/experiments/expyriment
python tearing-test.py

Note: for nvidia GPU, see https://learn.foundry.com/hiero/current/content/timeline_environment/usingviewer/synching_vblank.html
Psychopy

sudo apt-get install libusb-1.0-0-dev portaudio19-dev libasound2-dev
sudo add-apt-repository 'deb http://archive.ubuntu.com/ubuntu bionic main universe'
sudo apt install -t bionic libwebkitgtk-1.0-0

# if you prefer to use the system's python3
pip install swig psychopy

# if you prefer to use anaconda python:

wget https://raw.githubusercontent.com/psychopy/psychopy/master/conda/psychopy-env.yml
conda env create -n psychopy -f psychopy-env.yml
conda activate psychopy
conda install ipython numpy
