2. use conda to install some dependencies:

conda install configobj numpy scipy matplotlib pyopengl pillow spyder
conda install -c cogsci pyglet=1.2.4
conda install -c cogsci pygame=1.9.2a0

For moviestim2 or moviestim3

Install VLC (for moviestim2 but it gives an error, namely ‘global name vlc not found’)

Moviestim3 can be used instead of moviestim2, but it requires moviepy:

conda install -c jlaforet moviepy=0.2.2.11

Download psychopy source code and extract. In the terminal cd to the extracted psychopy source folder and run:

pip install -e .
