wget https://repo.anaconda.com/archive/Anaconda3-2021.05-Linux-x86_64.sh
chmod +x Anaconda3-2021.05-Linux-x86_64.sh
./Anaconda3-2021.05-Linux-x86_64.sh 
conda update -n base -c defaults conda

Expyriment environment

sudo apt-get install build-essential libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev libsdl1.2-dev libsmpeg-dev libportmidi-dev ffmpeg libswscale-dev libavformat-dev libavcodec-dev libfreetype6-dev
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, try:

mkdir ~/git
cd ~/git
