Is the upgrade to numpy 1.7 recommended for the current EPD 7.3-2? (I
am using it on both Macs and Linux). Best regards, Michael _______________________________________________ Enthought-Dev mailing list [hidden email] https://mail.enthought.com/mailman/listinfo/enthought-dev |
Hi Michael,
Numpy 1.7.0 has a significant memory leak, described here: Therefore we do not plan to build it for the EPD repo. We will reassess when 1.7.1 bugfix is released; the numpy team has not yet set a target date for release. hth,

This bug is fixed in the maintenance/1.7.x branch, and 2 days ago the developer 'certik' assured that there will be a maintenance release soon. Let's hope so, as I'm really tired of dancing around the datetime64[ns] bug with my timeseries.

Hey everybody,
after setting up a new Ubuntu sytem (12.10) and trying to run old code I ran into I problem I don't know how to fix: An image_plot, even the example https://github.com/enthought/chaco/blob/master/examples/demo/basic/cmap_image_plot.py , just produces axis with white content. Line plot, scatterplot, contourplot do as usual. I installed Chaco via apt, in a first attempt to fix this problem I updated it usin pip. Any Idea what could possibly go wrong? Thanks a lot, Felix _______________________________________________ Enthought-Dev mailing list [hidden email] https://mail.enthought.com/mailman/listinfo/enthought-dev |

Hey everybody, Without shelling into your system there is no easy way to figure out what is wrong, and I don't know that we have any offline image plotting unit tests. Are you saying that line and scatter plots work?
Perhaps there is a Numpy version conflict...? What version of Numpy do you have? Are you on 32 or 64 bit linux? If the latter, are you running a 32bit or 64bit Python? Are you using WxPython or Qt? If the latter, are you using Pyside or PyQt? I installed Chaco via apt, in a first attempt to fix this problem I If you're not opposed to the idea, I would strongly suggest using a Python distribution like Enthought EPD or Continuum's Anaconda (or any of the others listed at http://python.org/download/). I know that both EPD and Anaconda have working, tested versions of Chaco, with no hidden numpy/scipy/etc. version incompatibility weirdness.

After some trial and error, it found it works when I compiled with gcc 4.6.3, but not with gcc 4.7.1 or a 4.8 snapshot.

When I copied the _agg.so from EDP into my gcc 4.7.1 build, the image plot worked.

Thanks Lee,
you are a hero, that did the job for me... Peter thanks you as well for your answer. Indeed I am running a 64 bit system, with 64 bit Python. before copying _agg.so from EDP I tried to update enable via pip and run into this bug https://github.com/enthought/enable/issues/34#issuecomment-2029381 (X11 libraries not found on Ubuntu 11.10) I don't know if those are related, I might try this later again. Cool, first question on this mailing list, got a solution for a non trivial problem.

Hi,
I run into the same problem: ubuntu 12.10 and display of white canvas (due to gcc 4.7.2 in my case). I installed Chaco via apt. However I don't understand how to fix the problem: >When I copied the _agg.so from EDP into my gcc 4.7.1 build, the image >plot worked. Where can I find the _agg.so object and where exactly should I copy it? Thanks, Valentina _______________________________________________ Enthought-Dev mailing list [hidden email] https://mail.enthought.com/mailman/listinfo/enthought-dev |
Greetings, I like the look and feel of the new numpy reference. But, am I missing something or is there no way to search it? http://docs.scipy.org/doc/numpy/reference/ Ross On Saturday, November 30, 2013 8:25 PM, fioretti <[hidden email]> wrote:
