Python-matplotlib and dependencies

To day I tried to install python-matplotlib, but it dependet on, and tried to install wxpython and tk, which in turn depends on old usless gtk-1 and glib-1. All together 17 MB. Why is that, you can easily build this package without all those dependencies and as far as I know don't lose any functionality.

Thanks for the info. But shouldn't there it be a mechanism to not install the arch version of a python pakage if the correct version has been installed using e.g. pip already?
No. I think pip should be patched to inform pacman about its illegal operations in pacman territory.

Python-matplotlib: segmentation fault error

Hi All!
I'm new an the forum and for my first post I'd like to be expose an issue that I face with the matplotlib tool of python. More precisely, I recently used the apt package to install python, nympy and matplotlib on a linux 64b computer. Everything seemed to be working well expect that when I try to import matplotlib (import matplotlib.pyplot as m for eg.) I get a segmentation fault error.
I´ve been trough several forums trying to apply their suggestions but I could not overcome this issues. Do anybody can give me insight on how to fix this?
Thank you and have a good week-end!
L1011

Honestly I'm not familiar with apt on arch, but if you're comfortable installing software from AUR you can try the package build I just cooked up for matplotlib with python3 support:
http://aur.archlinux.org/packages.php?ID=49810
(I'm assuming you were trying to get python3 support, else you would have just installed python2-matplotlib with pacman...)

Installation order and dependencies of Essbase Products

Hi Experts,
I am soon to start a fresh EPM Installation on SUN SOLARIS SPARC. Just wanted to know the Installation order and dependencies on each services. The Instllation would be a Websphere based on 64 bit SUN SOL OS with 11.1.3.
the following are the essbase production which i have to Install.
Essbase Analytical services
Essbase Administration Services
Essbase Shared services
Application Provider services ( for Smart View ).
at present i am going thru the Read me Installation docs for all products, Would be great if you can give me a quick order of Installation so i can concentracte accordingly.
any quick reference DOC will also help
Cheers
MS

The installation order is not so important as the installer should install the components correctly, just install the products you want to on each machine.
When configuring you would configure shared services registry and shared services first.
It is worth reading through the install and config doc http://docs.oracle.com/cd/E12825_01/epm.111/epm_install_11114/launch.html
Installation sequence http://docs.oracle.com/cd/E12825_01/epm.111/epm_install_11114/ch03s01.html
"EPM System Installer enables you to install, configure, and deploy multiple products on a machine at one time. EPM System Installer installs components in the correct order, so you can select as many products as you want to install on a machine at one time"
Configuration Sequence - http://docs.oracle.com/cd/E12825_01/epm.111/epm_install_11114/ch04s03.html

Python segmentation fault with matplotlib and opencv2

Once again fellow archers, I am in need of your help.
I have a file, Test1.py, which uses cv2, pylab, and numpy.
Excluding either pylab or cv2 functions, I can make the rest of the script work, but when pylab is imported, calling cv2's imshow() function causes a "segmentation fault (core dumped)".
By the sound of it, I thought it might come from the underlying C stuff, rather than python.
So I ran it through gdb.
This is where I need help. I'm not sure how to interprete the backtrace, and I probably wouldn't know what to to if I were.
Perhaps a problem with glib or GObject?
Below are the python script in question (it a template for a school assignment), and the gdb trace.

Thank you so much!
This (ugly) workaround might have saved me from a lot of trouble with this semester's exercises.
Just to be clear, the solution is:
Import opencv
Call namedWindow
Do the rest of the imports
Do the rest of the script
Corect?
I'm hesitant to mark the thread as solved, as the problem is still very much there, this workaround just allows us to ignore it.

Conflict between python-pyqt4 and python-pyqt5

Hi!
When trying to use matplotlib in the Spyder Python IDE I get the following error
RuntimeError: the PyQt5.QtCore and PyQt4.QtCore modules both wrap the QObject class
It's obviously a conflict between pyqt4 and pyqt5. However, pyqt4 is a hard dependency of Spyder and pyqt5 is a hard dependency of matplotlib. Outside Spyder, matplotlib works fine.
Does anybody know how to resolve this conflict? Or is it a packaging issue? Shall I file a bug report? I think a discussion about matplotlib depending on Qt5 had already been going on here.

Does it work with https://aur.archlinux.org/packages/pyth … tlib-noqt/ ?
I think it's OK to open a bug report.

Can i use Python Matplotlib with labview?

I have a python code that i want to develop a User Interface for, i found Labview, but can i still use all the add-ons and modules when i run the script in labview? basically, i just want to develop a GUI for my code and I want to use all the modules and add-ons that I had in my code. Addons and modules such as pylab, matplotlib, numpy, scipy, and so on. Thanks!
Solved!
Go to Solution.

The only integration LabVIEW has with Python is that it can call scripts and use the output from those scripts. Here is an example of how to do that.
https://decibel.ni.com/content/docs/DOC-8995
I would use a Python GUI Framework to control your Python application. Here is a link to the Python Wiki on GUI Frameworks.

While matplotlib (0.98.5.2) usually took enormous amounts of memory, (during a period of time up to 1.5 Gigs working memory) which isn't good, after updating to 10.5.7 (from 10.5.6), things got worse. After a couple of minutes in which a couple of hundred pngs, (800x600, just a scientific graph) were plotted, it would go RuntimeError on me. And not just that. Python would quit with an error code 12. Something to do with memory allocation, even if it's the first thing after booting up. Malloc and stuff.
I'm pretty sure it's a matplotlib-thing as, other datahandling code without matplotlib kept working.
Good news though: with the Enthought edition these troubles disappear. Completely.

Nevermind that, I still get this error:
Python(9737) malloc: * mmap(size=65536) failed (error code=12)
* error: can't allocate region
* set a breakpoint in mallocerrorbreak to debug
Python(9737) malloc: * mmap(size=65536) failed (error code=12)
* error: can't allocate region
* set a breakpoint in mallocerrorbreak to debug
Python(9737) malloc: * mmap(size=65536) failed (error code=12)
* error: can't allocate region
* set a breakpoint in mallocerrorbreak to debug
libpng error: zlib failed to initialize compressor
which is an odd error since it has made 424 pngfiles without error. and memory wasn't full according to iStat.
And python doesn't just quit after this error. It keeps running, filling up working space memory. Grr.

Berkeley DB XML, Python, TEI and DTDs

Dear BDB XML experts,
I am developing a web application (Django based) that uses python to manipulate and query TEI based documents within a BDB XML container.
The XML documents I am loading into the container contain a reference to an external DTD, which in turn references .ent files. The documents contain entity references that require resolving.
I can successfully put the XML documents into the container if I include the contents of the DTD within each file, but the process fails if I do not include the contents of the DTD in the XML document and instead try to reference the DTD via a reference. Xquery queries also do not seem to work properly if the DTD contents is included within each XML document.
I have found references in the forums to the following JAVA code which appears to allow BDB XML to reference an external DTD in the file system from within the database (I may be wrong on this though):
XmlManagerConfig config = new XmlManagerConfig();
config.setAllowExternalAccess(true);
XmlManager manager = new XmlManager(config);
My query is, can the same be achieved using python? The BDB documentation specifies this as a JAVA only operation and does not mention it as possible using python.
Thanks for reading

Hi AL,
I have gathered quite a bit of experience with the Python bindings now, but I haven't been exactly in your situation. My experience has been that pretty much anything that you can do in Java you can do in Python but sometimes the syntax is a little different. From what I see Python does not have an XmlManagerConfig class but instead uses flags given to the XmlManager constructor. To do what you want to do I think you want (assuming from dbxml import *)
mgr = XmlManager(env, DBXML_ALLOW_EXTERNAL_ACCESS)

Help needed in understanding what Python is and ho...

Hi All,
I have read about python and i dont quite grasp the entire technical language behind it but there are some apps that i would like to install on my E71 but they require python. I have tried to download python form sourceforge but it has never worked. Thank you all for your assistance.
Solved!
Go to Solution.

Python is an interpreted programming language.
For Python applications to run, you need to install the Python runtime first.
For the E71, download the SIS file for S60 3rd Edition or S60 3rd Edition Feature Pack 1 (FP1) from:
http://sourceforge.net/project/showfiles.php?group_id=154155&package_id=171153&release_id=644640

Executable and dependencies

Labview 2012/Windows 7.
On my developemnt machine I created a project w all my vis to run a test. That works fine. I then created an exe and that works fine. Then I created an installer for the target machine and the code doesn't work. I get that its missing files and those files just happen to be listed under "dependencies" of the project on the devmnt machine. To name a few..."vi.lib", "instr.lib", nidmm_32.dll", niswitch_32.dll". In the build I included DAQmx and visa as well as the RT engine. I selected my "Main Menu" as the "startup vi. Main menu calls all of the "other vis" which are in folders in the project under main menu. The discussion grps have some confusing info. Should I put the "other vis" that my main menu calls in the "Always Include" box or when I select main menu as my startup vi Labview is smart enough to include those called vis??
What am I missing that I get an error when I port my code to the target machine ? ..."vi.lib", "instr.lib", nidmm_32.dll", niswitch_32.dll".

Hi Clint,
as you miss "nidmm.dll" I guess you need to install the NI-DMM driver as well with your exectable…

Assemble ant task and dependencies

We are in a process of moving from wasp 4.5 to OC4J R3.
We want to be able to assemble (and deploy) a bottom-up java web service using ant.
I look at the assemble ant task but I couldn't find out how to specify using that task the jars that will be copied to WEB-INF/lib or any other option like using a custom oracle-webservices.xml file to specify the dependencies or specifying a shard library to be used..
The documentation is really unclear about the subject.

What's your approach to pack the files?
Just use the assemble task to create the war structure and then add all the dependencies?
I'm new to OC4j but it seems a reasonable request to add dependencies with the ant task , just like when you use the input tag to specify which files should be in WEB-INF/classes.
The oracle-webservices.xml is another way to specify the web service (if i remember correctly) and I gave it as another example of where I looked to solve to problem.
It shouldn't be that hard to pack to war file myself... it's just annoying that when you come from WASP 4.5 which is over 3 years old and it's so easy and clear how to pack a bottom-up web service.

Python distutils and Arch

Was just reading through PEP 356: http://www.python.org/dev/peps/pep-0356/ which discusses the 2.5 python roadmap. Two things that have been deferred until 2.6 are bdist_deb and bdist_egg targets. I started wondering if there were modules to allow me to build .debs with distutils without having it built in....
I didn't check before I started wondering if it would be possible to write a distutils module that causes setup.py to spit out Arch PKGBUILDs. Apparently distutils will have requires, provides, and obsoletes keywords.
I love how easy it is to create source distributions using distutils... would be lovely if I could create PKGBUILD's just as easily.
I have no time to implement this or find out how it would be done, so I thought I'd put the idea out to the community and see if anybody else is interested or might try it.

Good thing I don't have much of that left, as my previous job was entirely focused on writing code with twisted.
I would recommend eventlet or gevent instead.
Any advantages of those over sockets?
