Installing Glue

There are several ways to install Glue on your computer:

Enthought Canopy

Platforms: MacOS X, Linux, and Windows

The Enthought Python Distribution includes most but not all non-trivial dependencies.

You can install Glue using:

pip install glueviz

You can then install any additional (optional) Glue dependencies by running:

glue-deps install

on the command line. For more information on glue-deps, see below

Standalone Application

Platforms: MacOS X

Mac users with OS X >= 10.7 can download Glue as a standalone program. This is the fastest way to get started with using Glue, but this application includes its own version of Python, and will not recognize any packages in other Python installations. If you want to use glue in your existing Python installation, follow instructions in the other sections.

Building from Source (For the Brave)

Platforms: MacOS X, Linux, and Windows

The source code for Glue is available on GitHub. Glue relies upon a number of scientific python libraries, as well as the Qt GUI library. Installing these packages is somewhat beyond the scope of this document, and unforunately trickier than it should be. If you want to dive in, here is the basic strategy:

  • Install Qt 4 and either PyQt4 or PySide. If at all possible, use the binary installers; building PyQt4 or PySide from source is tricky (this is a euphemism).
  • Install Glue using pip: pip install glueviz. Alternatively, git clone the repository and install via python install
  • Install Glue’s remaining dependencies by running glue-deps install. For more information on these dependencies see below.


Glue has the following required dependencies:

And the following optional dependencies are also highly recommended:

In addition to these, there are several other optional dependencies to suport various I/O and other optional functionality. Glue includes a command line utility glue-deps to manage dependencies:

  • Calling glue-deps list displays all of Glue’s required and optional dependencies, along with whether or not each library is already installed on your system. For missing dependencies, the program also provides a brief description of how it is used within Glue.
  • Calling glue-deps install attempts to pip install all missing libraries. You can install single libraries or categories of libraries by providing additional arguments to glue-deps install.

Tips for Ubuntu

Many dependencies can be reliably installed with apt:

sudo apt-get install python-numpy
sudo apt-get install python-scipy
sudo apt-get install python-matplotlib
sudo apt-get install python-qt4
sudo apt-get install pyqt4-dev-tools
sudo apt-get install ipython
sudo apt-get install python-zmq
sudo apt-get install python-pygments


Many dependencies can be reliably installed with:

sudo port install python27
sudo port install py27-numpy
sudo port install py27-scipy
sudo port install py27-matplotlib
sudo port install py27-pyqt4
sudo port install py27-ipython
sudo port install py27-pip

Running Glue

Installing glue from source will create a executable glue script that should be in your path. Running glue from the command line will start the program. Glue accepts a variety of command-line arguments. See glue --help for examples.


On Windows, installation creates an executable glue.exe file within the python script directory (e.g., C:\Python27\Scripts). Windows users can create a desktop shortcut for this file, and run Glue by double clicking on the icon.

Known issues

Issue with PyQt4 from conda

On certain Linux installations, when using Anaconda/conda to manage the Python installation you are using for glue, you may run into the following error when launching glue:

ImportError: /usr/lib/ undefined symbol: _ZNK7QSslKey9algorithmEv

This is due to a known issue with Anaconda where the system installation of Qt is used instead of the version shipped with Anaconda (see this issue if you are interested in a discussion of the issue). A simple workaround is to force glue to use PySide insead of PyQt4:

conda install pyside
export QT_API=pyside

after which glue will use PySide when started.
