Just released! EPD 7.3 plus beta version of EPD 8.0

Today we have for you not just one, but two exciting EPD releasesan update of EPD to 7.3 and a beta release previewing new features coming in EPD 8.0.

The EPD 7.3 update adds several new packages including Shapely, openpyxl, and a new package from Enthought named Enaml.  Enaml is a new package for rapidly building UIs using a very “Pythonic” declarative language heavily inspired by Qt’s QML langage.

EPD 7.3 also includes a host of package updates, including adding OpeNDAP support to the NetCDF4 package. Overall over 30 packages have been updated, including Cython, IPython, pandas, basemap, scikit-learn, Twisted and SQLAlchemy.

EPD 8.0 beta takes all that we know and love in EPD 7.x and adds an all-new graphical development and analysis environment.  The new GUI is focused on providing a fast, lightweight interface designed for scientists and engineers.  Some of the key features are:

  • A Python-centric text editor including tab-completion plus on-the-fly code analysis.
  • An interactive Python (IPython) prompt integrated with the code editor to enable rapid prototyping and exploration.
  • A Python package manager to make is easier to discover, install, and update packages in the Enthought Python Distribution.
  • Integrated documentation, both on the GUI itself and standard online documentation.

Which version should you install?  EPD 7.3 is the current production release and has the most testing behind it.  If you want to try out EPD 8.0 beta we would love to hear what you think.  EPD 8 is designed to work with earlier versions so once you install the GUI you can either setup a new EPD environment or tell it to use your existing one.  And don’t worry, it’s safe — it won’t modify your existing EPD.

As always, if you have an existing EPD 7.x install that you want to keep you can update all of the Python packages to EPD 7.3 by running the command “enpkg epd” from the command line.  Or, if you have installed the EPD 8 GUI, just open the package manager, select the ‘EPD’ package and click ‘Install’.  It will update you EPD 7.x environment for you.

PyGotham Sneak Peek: Interactive Plots with Chaco

Visualization is an important part of any analysis. While well-designed static plots can tell rich stories about data, sometimes a little interactivity can go a long way to build intuition around a subject. Chaco is an open source plotting library that allows developers to create highly interactive plots that offer multiple perspectives on a piece of analysis. Enjoy!

GPU-palooza: May 21, NYC

Enthought is proud to sponsor the NYC HPC-GPU Supercomputing meetup on May 21st, 2012. This meeting will focus on the GPU and Python (what else?).

A happy coincidence brings together three GPU wise men at this meetup. Andreas Klockner is the author of PyCUDA and PyOpenCL. Nicolas Pinto comes to us via MIT with an extensive background in machine learning/GPU-related research. Last but not least, Enthought’s own Sean Ross Ross will share the latest on OpenCL and CLyther.

It promises to be a GPU-accelerated night! The room is filled to capacity I believe, but it’s not uncommon for people to get off the waiting list.

Please come by and say hello!

BioInformatics at Scipy: It’s Alive!

It's Alive!

We are pleased to announce the 2012 SciPy Bioinformatics Workshop held in conjunction with SciPy 2012 this July in Austin, TX.

Python in biology is not dead yet… in fact, it’s alive and well!

Remember just a few short years ago when BioPerl ruled the world? Just one minor paradigm shift* later and Python now has a commanding presence in bioinformatics. From Python bindings to common tools all the way to entire Python-based informatics platforms, Python is used everywhere** in modern bioinformatics.

If you use Python for bioinformatics or just want to learn more about how its being used, join us at the 2012 SciPy Bioinformatics Workshop. We will have speakers from both academia and industry showcasing how Python is enabling biologists to effectively work with large, complex data sets.

The workshop will be held the evening of July 19 from 5-6:30.

More information about SciPy is available on the conference site:

!! Participate !!

Are you using Python in bioinformatics? We’d love to have you share your story. We are looking for 3-4 speakers to share their experiences using Python for bioinformatics.

Please contact Chris Mueller at chris.mueller [at] and Ray Roberts at rroberts [at] to volunteer. Please include a brief description or link to a paper/topic which you would like to discuss. Presentations will last for 15 minutes each and will be followed by a panel Q&A.

* That would be next generation sequencing

** Yes, we aRe awaRe of that otheR language used eveRywhere, but let’s celebRate Python Right now.
