ETS 3.0.0b1 Released!

I am very pleased to announce that ETS 3.0.0b1 has just been tagged and released!

All ETS sub-projects, including Traits, Chaco, Mayavi, and Envisage, have been tagged and released in one form or another (alpha, beta, final) as part of this effort. All ETS projects have now been registered with PyPi and source tarballs have been uploaded! As a result, for the first time ever, you can now easy_install all of ETS via a simple command like:

    easy_install ETS

Or, alternatively, you can get only specific projects with commands like:

    easy_install Mayavi


    easy_install Chaco

We anticipate the final release of ETS 3.0, and all of its sub-projects at their current version number, in a matter of weeks. Please join us in helping make this final release the most robust release it can be by participating in this beta shakeout period. Discussions about the status of ETS and its sub-projects happens on the enthought-dev mailing list, whose home page is at:

Thank you to all who have worked so hard on making this release possible!

Enthought Tool Suite

The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and open source participants, which we use every day to construct custom scientific applications. It includes a wide variety of components, including:

  • an extensible application framework
  • application building blocks
  • 2-D and 3-D graphics libraries
  • scientific and math libraries
  • developer tools

The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes. More information is available for all the packages within ETS from the Enthought Tool Suite development home page at


“I set out to rebuild an application in one week that had been developed over the last seven years (in C by generations of post-docs). Pyface and Traits were my cornerstones and I knew nothing about Pyface or Wx. It has been a hectic week. But here … sits in front of me a nice application that does most of what it should. I think this has been a huge success. … Thanks to the tools Enthought built, and thanks to the friendly support from people on the [enthought-dev] list, I have been able to build what I think is the best application so far. I have built similar applications (controlling cameras for imaging Bose-Einstein condensate) in C+MFC, Matlab, and C+labWindows, each time it has taken me at least four times longer to get to a result I regard as inferior. So I just wanted to say a big “thank you”. Thank you to Enthought for providing this great software open-source. Thank you for everybody on the list for your replies.”

“I’m currently writing a realtime data acquisition/display application I’m using Enthought Tool Suite and Traits, and Chaco for display. IMHO, I think that in five years ETS/Traits will be the most comonly used framework for scientific applications.”

    I am using SciPy on a fresh Ubuntu 8.04 VM. When I did an “easy_install ETS” I got an error in SciMath about “unixccompiler”.
