$ conda install numpy. $ conda create -n py3k anaconda python = 3. There are two variants of the installer: Miniconda is Python 2 based and Miniconda3 is Python 3 based. Note that the choice of which Miniconda is installed only affects the root environment. Regardless of which version of Miniconda you install, you can still install both Python 2.x and Python 3.x environments. The other difference is that the Python 3 version of Miniconda will default to Python 3 when creating new environments and building packages. So for instance, the behavior of.
Hi, I wanted to let you know that the latest release of IEP can create a Python environment for you. If this works was well as we think it does, this can replace Pyzo; instead of downloading a big installer with many scientific Python packages (including IEP), you can download IEP, and create an environment from there.
IntroductionIEP (pronounced as 'eep') is a cross-platform Python IDE focused on interactivity and introspection, which makes it very suitable for scientific computing. Its practical design is aimed at simplicity and efficiency. IEP is written in Python 3 and Qt. Binaries are available for Windows, Linux, and Mac. Python is a general-purpose programming language that is easy to learn and which can help you work faster and integrate systems more efficiently. Python features high-level data structures, as well as an effective approach to object-oriented programming.
We have not announced this release yet, because we'd first like to get feedback on this new approach. We are in particular interested in how Pyzo users like it, so please give it a try and let us know what you think! Note that the environment that IEP creates is very similar to that of Pyzo.
Both are based on conda. The main difference is that it installs PyQt4 instead of PySide (but you can conda install pyside-pyzo if you want). Further, because the IDE is separated from the environment, there should be less problems with updating packages.
Regards, Almar Christophe Bal 1/10/2015, 12:25 น. Although it is great that IEP will be able to build a functioning scientific python environment, I still like the idea of having Pyzo for people like me that just want to download one file and start programming right away.
As an Engineering student that came from a background programming my assignments on Matlab, it was already kind of a challenge switching to Python and learning the syntax, nuances, etc. Pyzo made the transition from Matlab to Python much easier.
If I would have had to create an environment, I'm not sure I would have been able to make the switch. In short, for Python veterans, I guess the issue of having Pyzo, or having IEP create a python environment is not that big a deal.
However, for people new to Python, I think it is very important to keep Pyzo around. Almar Klein 9/10/2015, 0:29 น. Hi Samuel, Thanks a lot for your reaction, this is very valuable. Although it is great that IEP will be able to build a functioning scientific python environment, I still like the idea of having Pyzo for people like me that just want to download one file and start programming right away.

In short, for Python veterans, I guess the issue of having Pyzo, or having IEP create a python environment is not that big a deal. However, for people new to Python, I think it is very important to keep Pyzo around. I understand that for newcomers the process should be as smooth and unconfusing as possible. We tried to do this in IEP by making the installation of an environment in as few clicks as possible (2 I think).
Still, I agree that its a hurdle. Could you perhaps explain what parts of the installation process are confusing or could be improved? Or is it mainly the fact that after installing IEP, a user thinks he's done and might be confused being prompted with something else to install? (In which case we might need to improve the communication.) We hope that we can get this easy enough to also help newcomers and Matlab converts.
Pyzo is a lot of work to maintain and has had issues wrt updating packages. Thanks, Almar Samuel Garcia 9/10/2015, 10:23 น. Hi Almar, I just downloaded IEP and created a miniconda environment.
Creating the environment was pretty straightforward (just follow the prompts and click). However, once the miniconda environment was created I had some issues. First issue: When I tried to run some code that uses Matplotlib to plot some graphs, the code would run without errors, however, no graph windows would be created. Second issue (minor): By default the miniconda environment does not come with ipython, so a new user would have to type in 'pip install ipython'. Not a big deal, but still an extra hassle for a new Python user that has no idea how to use the console to install things. As a workaround, in IEP under shell configurations, in the 'exe' box I put in the location of the Pyzo install folder (C: pyzo2015a python.exe) and then everything works like in Pyzo.
But this requires installation of Pyzo first. The second issue is not a big deal, but the issue where I couldn't get the miniconda installation to plot graphs is a deal breaker. I would still recommend Pyzo to new Python converts because everything works right away with no hassle.
One reason I like Pyzo is that once you download the install file, you can take it on a USB stick and install everything (all scientific packages) even without an internet connection. Even if IEP is able to create a Pyzo environment clone, if I put it on a USB stick and try to install on a computer without internet connection, I would not be able to create the environment. In short, I hope you guys keep releasing Pyzo for all the new converts that want to get up and programming right away, b/c sometimes they might get discouraged if they run into problems.Samuel Almar Klein 9/10/2015, 14:24 น.
You'd need to put plt.ion at the top of your code. In Pyzo we modified the Matplotlib config file to turn it on by default, but updating MPL would overwrite the config, effectively turning it off.
The miniconda env provides a more 'vanilla' Matplotlib. Second issue (minor): By default the miniconda environment does not come with ipython, so a new user would have to type in 'pip install ipython'. Not a big deal, but still an extra hassle for a new Python user that has no idea how to use the console to install things. Even better would be 'conda install ipython'. We do mention this possibility at the end of the install, but I understand this might not be clear enough.
I'll think about what we can do here. As a workaround, in IEP under shell configurations, in the 'exe' box I put in the location of the Pyzo install folder (C: pyzo2015a python.exe) and then everything works like in Pyzo. But this requires installation of Pyzo first.

Food for thought. I can't promise though.
As I said, each Pyzo release is a lot of work. There is certainly room for improvement on IEP's installer.
And maybe we can keep a complete all-in installer for Win64 (which should cover most of these convert users). Samuel Garcia 9/10/2015, 18:23 น. Hi Almar, Thanks for the plt.ion tip.
After playing around with the environment creator feature of IEP, it seems very nice. I think it would be a cool feature if when creating the miniconda environment it would also install ipython. I do wonder how you guys got the Pyzo environment significantly smaller than the miniconda environment created in IEP. (Pyzo install directory: 729 MB vs Miniconda install directory: 1.8 GB). Finally, what is the difference between pyside and pyqt4? Is there any pros/cons for scientific computing? What about for creating GUI's?
When I get my new Mac I'll try using IEP to create a miniconda environment and let you know how my experience on Mac is. Thanks again for all your hard work on Pyzo and IEP, and also for the online support.Samuel Luca Matteini, 5:50 น. Hi Almar, a (Python) newbie point of view. I installed Pyzo on a machine, and started writing some test code, a few graphs with matplotlib, everything fine. Then I installed a IEP 3.7 on a different machine, followed the few clicks to request the scientific packages. It took a (relative) long time to download and install (maybe this second machine is a bit slow too).
Almar: I was told by my advisor to learn scipy. So I looked for scipy, downloaded, and installed, then found that there was a whole mess of other things to install. Open source projects are fun, but when I needed to quickly learn a new software and found it to be very involved, I paniced.
I search for a half hour until I came across the pyzo website. Whey I clicked on the Pyzo website, I immediately saw that 'ok, this is a whole dam thing in one package.' The phrase 'Python to the people' is very effective in saying what this project is for. It immediately told me 'This is what I need to start using scipy'. After a quick search to confirm that this wasn't bloatware or malware, I tried it, it ran the code without arguement, and I spread the word. From a marketing point of view, Pyzo is far superior to IEP - as a novice, when I look at the website, my 'quick find a new software' mind says 'Just another editor'. In fact, it wasn't until after a month of using 'Pyzo' that I realized, OH!
It has an anaconda back end. IEP is the product I am really using. I now know that a huge value in Pzyo is the IEP, but for me, I needed the whole package. Really though, I think it is like my Toyota: I don't really care what the design engineers are doing, as long as the car gets me to work consistently without tons of time consuming maintenance. So if you say 'IEP can do it all' that's pretty much the same as 'Pyzo can do it all' except that the phrase 'Pyzo: Python to the People' is very catchy.
Either way, Thanks for pretty much starting my career by providing a shortcut allowing me to learn and produce scientific data on time. Steve Almar Klein, 6:28 น. Thanks for the plt.ion tip. After playing around with the environment creator feature of IEP, it seems very nice.
I think it would be a cool feature if when creating the miniconda environment it would also install ipython. We decided to not include it because it made quite a bit of difference in size (and thus installation time), and since its easy to install later. But we can add a checkbox to install it. I do wonder how you guys got the Pyzo environment significantly smaller than the miniconda environment created in IEP. (Pyzo install directory: 729 MB vs Miniconda install directory: 1.8 GB) I don't know where you get the 1.8GB from, a fresh miniconda install with scientific packages in about 870MB for me.

You can indeed expect a somewhat larger size though, because conda stores the compressed archives of packages that it installes (and we remove these in Pyzo). Finally, what is the difference between pyside and pyqt4? Is there anypros/cons for scientific computing? What about for creating GUI's?
They are (almost) compatible. PyQt4 is more stable, which is why Continuum decided to go with it. It has a less liberal license though; if you are selling software basded on PyQt4, you'd need to pay Riverbank some money. PySide is LGPL. Regads, Almar Almar Klein, 6:32 น.

AlmarWhat OS are you on? And what is the rest of the error message (after DLL load failed)? The OS is Windows Vista x86, don't remember the exact flavor, have it on an old laptop. I can check better and return to you with the message, though I deliberately cut it, as it was in local language - not sure how translating it makes sense. Anyway I'll try in a few hours, when I'll be home You can try running 'conda install matplotlib -f' to try forcing a reinstall. Ok, will try that one too Thanks again, Lou Almar Klein, 7:12 น.
Almar, everything is working now, and apparently I did nothing, but.restarting. the system: that makes me pretty sure it's all about the environment variables, since now I see PATH set to 'C: miniconda3;C: miniconda3 Scripts' Then. The 'Restart your system now' message that we see often in installers, here makes sense! For the report, this system runs Windows Vista Home Premium, SP2, 32-bits. Falls in the category of the ill-fated ones, I keep it with me for compassion:) Thanks again, sorry for the false alarm, Lou Luca Matteini, 14:01 น.
