Debian GNU/Linux If you are using Debian GNU/Linux and it is recommended that you use system packages to install Gunicorn except maybe when you want to use different versions of Gunicorn with virtualenv. This has a number of advantages:. Zero-effort installation: Automatically starts multiple Gunicorn instances based on configurations defined in /etc/gunicorn.d. Sensible default locations for logs ( /var/log/gunicorn). Logs can be automatically rotated and compressed using logrotate.

Improved security: Can easily run each Gunicorn instance with a dedicated UNIX user/group. Sensible upgrade path: Upgrades to newer versions result in less downtime, handle conflicting changes in configuration options, and can be quickly rolled back in case of incompatibility. The package can also be purged entirely from the system in seconds.

Recommended hardware The minimum requirement for PsychoPy is a computer with a graphics card that supports OpenGL. Many newer graphics cards will work well.

Ideally the graphics card should support OpenGL version 2.0 or higher. Certain visual functions run much faster if OpenGL 2.0 is available, and some require it (e.g. If you already have a computer, you can install PsychoPy and the Configuration Wizard will auto-detect the card and drivers, and provide more information.

It is inexpensive to upgrade most desktop computers to an adequate graphics card. High-end graphics cards can be very expensive but are only needed for very intensive use. Generally nVidia and ATI (AMD) graphics chips are high-performance than Intel graphics chips so try and get one of those instead. Some graphics cards that are known to work with PsychoPy; that list is not exhaustive, many cards will also work. Dependencies You need a copy of Python 2.7.x from here, wxPython and probably pyo (or use an alternative audio library listed below). None of these support pip install yet so you need to download them:. Imap folders missing. Python itself: ( version 3.x is not supported yet ).

What Is Gevent

wxPython:. pyo audio:. PyQt4 or PyQt5 are handy but not required and need manual installation Then, if you want everything available you could paste this in to your terminal/commandline and go and get a coffee (will take maybe 20mins to download and install everything?).
