New features in the Canopy Data Import Tool Version 1.1:
Support for Pandas v. 20, Excel / CSV export capabilities, and more
We’re pleased to announce a significant new feature release of the Canopy Data Import Tool, version 1.1. The Data Import Tool allows users to quickly and easily import CSVs and other structured text files into Pandas DataFrames through a graphical interface, manipulate the data, and create reusable Python scripts to speed future data wrangling. Here are some of the notable updates in version 1.1:
For those currently familiar with Canopy, in this blog we’ll review the major new features in this exciting milestone release, and for those of you looking for a tool to improve your workflow with Python, or perhaps new to Python from a language like MATLAB or R, we’ll take you through the key reasons that scientists, engineers, data scientists, and analysts use Canopy to enable their work in Python.

No dataset is perfect and most datasets that we have to deal with on a day-to-day basis have values missing, often represented by “NA” or “NaN”. One of the reasons why the Pandas library is as popular as it is in the data science community is because of its capabilities in handling data that contains NaN values.
We’ve had a number of major product development efforts underway over the last year, and we’re pleased to share a lot of new announcements for 2017:
A New Chapter for the Enthought Python Distribution (EPD):
Python 3 and Intel MKL 2017
In 2004, Enthought released the first “Python: Enthought Edition,” a Python package distribution tailored for a scientific and analytic audience. In 2008 this became the Enthought Python Distribution (EPD), a self-contained installer with the "enpkg" command-line tool to update and manage packages. Since then, over a million users have benefited from Enthought’s tested, pre-compiled set of Python packages, allowing them to focus on their science by eliminating the hassle of setting up tools.
Fast forward to 2017, and we now offer over 450 Python packages and a new era for the Enthought Python Distribution; access to all of the packages in the new EPD is completely free to all users and includes packages and runtimes for both Python 2 and Python 3 with some exciting new additions. Our ever-growing list of packages includes, for example, the 2017 release of the MKL (Math Kernel Library), the fruit of an ongoing collaboration with Intel.
The New Enthought Deployment Server:
Secure, Onsite Access to EPD and Private Packages
Today we officially release Canopy Geoscience 0.10.0, our Python-based analysis environment for geoscience data.
Canopy Geoscience integrates data I/O, visualization, and programming, in an easy-to-use environment. Canopy Geoscience is tightly integrated with Enthought Canopy’s Python distribution, giving you access to hundreds of high-performance scientific libraries to extract information from your data.
The Canopy Geoscience environment allows easy exploration of your data in 2D or 3D. The data is accessible from the embedded Python environment, and can be analyzed, modified, and immediately visualized with simple Python commands.
Feature and capability highlights for Canopy Geoscience version 0.10.0 include:
Read and write common geoscience data formats (LAS, SEG-Y, Eclipse, …)
3D and 2D visualization tools
Well log visualization
Conversion from depth to time domain is integrated in the visualization tools using flexible depth-time models
Integrated IPython shell to programmatically access and analyse the data
Integrated with the Canopy editor for scripting
Extensible with custom-made plugins to fit your personal workflow
Today Enthought announced that it is now the worldwide distributor for PyXLL, and we’re excited to offer this key product for deploying Python models, algorithms and code to Excel. Technical teams can use the full power of Enthought Canopy, or another Python distro, and end-users can access the results in their familiar Excel environment. And it’s straightforward to set up and use.
Installing PyXLL from Enthought Canopy
PyXLL is available as a package subscription (with significant discounts for multiple users). Once you’ve purchased a subscription you can easily install it via Canopy’s Package Manager as shown in the screenshots below (note that at this time PyXLL is only available for Windows users). The rest of the configuration instructions are in the Quick Start portion of the documentation. PyXLL itself is a plug-in to Excel. When you start Excel, PyXLL loads into Excel and reads in Python modules that you have created for PyXLL. This makes PyXLL especially useful for organizations that want to manage their code centrally and deploy to multiple Excel users.
Creating Excel Functions with PyXLL
To create a PyXLL Python Excel function, you use the @xl_func decorator to tell PyXLL the following function should be registered with Excel, what its argument types are, and optionally what its return type is. PyXLL also reads the function’s docstring and provides that in the Excel function description. As an example, I created a module my_pyxll_module.py and registered it with PyXLL via the Continue reading →
Enthought Canopy 1.3 is now available and users should see the update notification in the bottom right corner of the Canopy welcome screen (as shown in the image below). This is a fairly small update primarily focused on bug fixing and stability improvement. The biggest change is the move to Python 2.7.6 from 2.7.3.
The bottom right of the Enthought Canopy window notifies users to available updates
Python 2.7.6 rolls up a couple of minor updates to the core Python environment. The most important changes from our perspective are a number of security fixes required by some users as well as fixes for Mac OS “Mavericks.” Details can be found in the Python release notes, but in general the change should be transparent to most users. The only caveat is for users building Python eggs with native C or FORTRAN extensions and publishing those eggs to users who may still be running earlier versions of Canopy or Python 2.7.3 in general. In this case, it is safest to continue building against earlier versions of Canopy.
But isn’t updating Python versions painful you may ask? In the past, yes, updating to a new Python version often required a new Python install and then re-installing all of your custom packages. However, with Canopy’s auto-update mechanism, it’s simply a matter of clicking the “Update available” link and choosing “Install and relaunch” or “Install after quit.” Canopy will automatically update the core Python installation and restart without impacting your environment. Additionally, whether you are running Canopy 1.1, 1.1.1, or 1.2, Canopy will jump straight to 1.3 and get you all of the latest updates.
We encourage all users to update to Canopy 1.3 as the 1.2 and 1.3 versions include a large number of stability fixes as well as cleaning up a lot of other less serious, but still important aspects of the user experience. For those new to Canopy, you can get Canopy here.
Enthought Canopy makes updates convenient with automatic downloads that install without impacting user environments
Canopy 1.2 is out! The release of Mac OS “Mavericks” as a free update broke a few features, primarily IPython, so we held the release to try to make sure everything worked. That ended up taking longer than we wanted, but 1.2 is finally out and adds support for Mavericks. There is one Mavericks-specific, Qt font issue that we are working on correcting which causes the wrong system font to be selected so UI’s look less-nice than they should.
Enthought Canopy integrated into PTVS
The biggest new feature is integration with Microsoft’s Python Tools for Visual Studio (PTVS) package. PTVS is a full, professional-grade development IDE for Python based on Visual Studio and provides mixed Python/C debugging. The ability to do mixed-mode debugging is a huge boon to software developers creating C (or FORTRAN) extensions to Python. Canopy v1.2 includes a custom DLL that allows us to integrate more completely with PTVS and solves some issues with auto-completion of Python standard library calls.
Beyond PTVS, we have added the Qt development tools, such as qmake and the UIC compiler, to the Canopy installation tree. These tools are available on all platforms now and enable Qt developers to access them from Canopy directly rather than having to build the tools themselves.
Canopy 1.2 includes a large number of smaller additions and stability improvements. Highlights can be found in the release notes and we encourage all users to update existing installs. As always, thanks for using Canopy and please don’t hesitate to drop us a note letting us know what you like or what you would like to see improved.
