Re: [Matplotlib-users] Runtime Error on Solaris - Error Closing Dupe File Handle
It seems like it is a conflict of libraries...I've zeroed in to these two errors: /usr/include/unistd.h:496:75: error: conflicting declaration of C function 'void swab(const void*, void*, ssize_t)' and /usr/include/stdlib.h:144:13: note: previous declaration 'void swab(const char*, char*, ssize_t)' I executed a find command and here's what came up: ~>sudo find / -name stdlib.h */opt/csw/include/c++/4.9.2/tr1/stdlib.h* /opt/solarisstudio12.4/lib/compilers/include/CC/gnu/stdlib.h /opt/solarisstudio12.4/lib/compilers/include/CC/stlport4/stdlib.h /opt/solarisstudio12.4/lib/compilers/CC-gcc/include/c++/4.8.2/tr1/stdlib.h */usr/include/stdlib.h* >From what it seems, it's calling stdlib.h from the /usr/include folder when it should be calling it from /opt/csw/include. I'm going to look into setup.cfg (that or perhaps hack setup.py) and see if it's at all possible to change it so that it looks in the right one, and then I'll try building it again.

Maybe you can do this with an environment variable? export CC=/usr/bin/cc It does look like there is a problem with scrambled environments. The redefinition warning looks potentially troublesome; and the error looks like a conflict between two versions of the standard C library. From "man swab" on Solaris: NAME swab - swap bytes SYNOPSIS #include void swab(const char *src, char *dest, ssize_t nbytes); XPG4, SUS, SUSv2, SUSv3 #include void swab(const void *restrict src, void *restrict dest, ssize_t nbytes); I think you want the second version, consistently, but something is also hitting the first version. Maybe "XPG4" or one of the other 4 options needs to be defined when each library is compiled with /usr/bin/cc? I think the stdlib declaration is old; the unistd version is more modern. That's all very vague, I know. Obviously, I don't actually know how to solve the problem.

I think there is on open bug about compilation failures on Solaris which we never sorted out due to not having access to a test machine.

Re: [Matplotlib-users] Runtime Error on Solaris - Error Closing Dupe File Handle
Bryan, If you subscribe to the list you will be able to post with out moderation. Does this happen with any of the other sample data? I don't think that `get_sample_data` is doing you any good here as you are passing it an absolute path (from `os.getcwd()`) which is passed into `os.path.join` which when it encounters and absolute path discards everything to the left so that line is just returning back your input. Does it work to open any other png or does _only_ this png have issues? You are reaching into the nominally private parts of the mpl api here, I would suggest using `mpl.image.imread` instead. It might be worth using something like PIL/pillow, imread ( https://pypi.python.org/pypi/imread), imageio (https://imageio.github.io/) or scikit-image for alternate implementations of png readers. None of the core developers have access to a Solaris machine so it is very difficult for us to provide much better help on this.

Re: [Matplotlib-users] Runtime Error on Solaris - Error Closing Dupe File Handle
Bryan, First off, avoid importing things from modules that start with an underscore. Because Python doesn't have semantics for public/private APIs like C++ and Java does, the underscore is treated as an indicator to developers that it is to be treated as private. The implication is that we are free to change the API of "private" modules and functions between releases, without warning or recourse, which would lead to breakage of your scripts if you use them. So, use it at your peril. I would recommend using plt.imread() instead, or use the Pillow package to read your data as a numpy array that you can then plot. Now, onto your issue. I suspect it might be related to changes we made in 1.4 to have a cross-platform file-handle. However, the solaris platform is not regularly tested by anybody, so it is quite likely we broke something there. Now, in the master branch on github, we completely rewrote nearly all of the C++ code, so I while it may still be broken there, perhaps we might get a more useful error message or something different entirely? Can you try building from the master branch and letting us know? Cheers! Ben Root P.S. - The script in question wasn't perhaps written originally by a former Meteorologist colleague from the University of Oklahoma? ;-) If it was, he was my officemate!

[Matplotlib-users] Runtime Error on Solaris - Error Closing Dupe File Handle
Good afternoon, My name is Bryan Williams. I work for the Florida Forest Service in their Forest Logistics and Support Bureau. I’m working on a program that takes weather data and visualizes it using matplotlib and Basemap. I’m currently having an issue with matplotlib 1.4.3 for Python 3.4.3 running under Solaris 5.10. I am getting a Runtime Error whenever I try calling the read_png file from matplotlib._png. (I’m using this to add a small .png file of the Forest Service’s sheld to the picture). The error is the following: Traceback (most recent call last): File "drawmaps.py", line 845, in arr_lena = read_png(fn) RuntimeError: Error closing dupe file handle I don’t quite understand the error I’m getting, and as you can see, the traceback gives very little information. I also tried Google for help, but to no avail; entering the error message as is into Google doesn’t return anything relating to the problem, and putting quotes around “Error closing dupe file handle” yields about 10 results, with one of them being an unanswered question from 2014 regarding the same issue. As per your request on the website, here’s what I get from uname –a: SunOS [server name withheld] 5.10 Generic_141444-09 sun4v sparc SUNW,SPARC-Enterprise-T5220 I built Python 3.4.3 from source and installed matplotlib through pip, and didn’t make any changes to the matplotlibrc file. I was able to reproduce the problem again running these commands in the Python interactive prompt, which emulates the snippet of script that causes the error: Python 3.4.3 (default, May 15 2015, 13:52:23) [GCC 4.9.2] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> from matplotlib._png import read_png >>> from matplotlib.cbook import get_sample_data >>> import os; path=os.getcwd() >>> fn = get_sample_data(path + '/resources/shield.png', asfileobj=False) >>> arr_lena = read_png(fn) Traceback (most recent call last): File "", line 1, in RuntimeError: Error closing dupe file handle If you’d like a copy of the problem script, please let me know.

[Matplotlib-users] Runtime error with matplotlib in IDLE
I have an error when running my script using matplotlib using IDLE. I suspect it is something to do with either numpy or matplotlib and I was wondering if any other users have had a similar problem. I have recently installed Python, matplotlib and numpy, I have not had it working correctly using IDLE on this machine. The error message is: Runtime Error! Program: C:\Python27\pythonw.exe This application has requested the Runtime to terminate it in an unusual way. Please contact the application's supporter team for more information. The window header says Microsoft Visual C++ Runtime Library (which seems to be about debugging). The error occurs about 50% of the time. When I run my script in the command line it runs fine everytime. I am using matplotlib and generating a pdf. If I remove the pdf generation step I still get the error. But running another script (on the csv module) don't seem to generate the error. I have searched on the internet without luck (suggestion of installing visual studio which I have got) or posting to the scipy list (well Im not using scipy). I am using Win7 32 bit and matplotlib 1.1 and numpy 1.6.1 and python 2.7. Has anyone else had similar message?

Re: [Matplotlib-users] Runtime Error - Need Advice
Thanks for all your suggestions Christoph. Launching the Tk Python Shell
instead of PythonWin seems to work consistently - I get the correct plot
figure and the correct log_plot.png file created everytime I run the
script. I never did install Ipython, but I'll consider that for a future
upgrade.

I can now reproduce this. It seems the same old problem that PythonWin
can not reliably run matplotlib because successive runs of the script
use the same interpreter. Ipython should work. Append pylab.close() to
your script; at least it will not crash on the second run.

I am not sure what's going on. The script you posted imports pylab in
the first line. It should be defined. The scrit works just fine after
the proposed changes, even from Pythonwin. Did you completely quit
Pythonwin after the crashes and made sure no corrupted python instance
was left running? Please send the version string of your python
installation.

I tried something that seems to work consistently - I get the correct plot
figure and the correct log_plot.png file created everytime I run the
script.
>From the Start menu, I chose All Programs-Python2.5-IDLE (Python GUI)
instead of All Programs-Python2.5-PythonWin, which creates the Tk Python

Does this make sense?

At this point a Windows user may need to step in. I know nothing about
PythonWin. My suspicion is that this is a problem of dueling event
loops, and one solution would be to use ipython instead of pythonwin.

I am not sure what's going on. The script you posted imports pylab in
the first line. It should be defined. The scrit works just fine after
the proposed changes, even from Pythonwin. Did you completely quit
Pythonwin after the crashes and made sure no corrupted python instance
was left running? Please send the version string of your python
installation.

At this point a Windows user may need to step in. I know nothing about
PythonWin. My suspicion is that this is a problem of dueling event
loops, and one solution would be to use ipython instead of pythonwin.

Re: [Matplotlib-users] Runtime Error - Need Advice
Use pylab.savefig('log_plot'). Also saving the figure to file and
showing it interactively in the same script might involve switching
backends, which might not work as expected.
It is advisable to downgrade to numpy 1.3.

I suspect this is the problem: numpy-1.4.0 is considered broken and has
been withdrawn. Specifically, it introduces binary incompatibility with
programs compiled against prior versions of numpy, including matplotlib.
If you go back to the numpy sourceforge site now, I think you will see
an earlier version that you can install in place of 1.4.0 (after
removing the latter).

Re: [Matplotlib-users] Runtime Error - Need Advice
Change the last line to pylab.show() and it should work.
Anyway, this example should not crash the interpreter. I can reproduce
the crash on Python 2.4, 2.5, and 2.6 (32 and 64 bit) on Windows with
mpl 0.99.1 but not on Ubuntu 9.1 with mpl 0.99.0.
The shortest example that crashes is:
python -c "import pylab;pylab.subplot(111).figure.show()"
or on the interactive prompt:
>>> import pylab
>>> pylab.subplot(111).figure.show()
>>> exit()
Fatal Python error: PyEval_RestoreThread: NULL tstate
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

Plots a figure on the screen that looks correct, then the following error
(when I click OK, PythonWin closes)
Any advice would be appreciated. Maybe it's an installation or setup
issue, but I'm pretty knew to Python programming and don't know how to
debug this.

[Matplotlib-users] Runtime Error from savefig( )
Good afternoon group, I am developing an application that had always before plotted a variable 2D numpy array of floats using contourf(), and then saved the figure produced as .png. Certain runs of the application (the ones with best precision) result in a failure while saving the figure using savefig(), and as consequence the message says at the end: "Runtime Error: Failure to gain raw access to bitmap data", here is the complete complaint, does someone know what is happening please? I use windows machines and Python 2.5.4.

Sorry, cutils.py is a part of a new config package we have been working on,
which ships with matplotlib but is not activated. I think you need to edit
your matplotlib/__init__.py instead, just make the same changes.
Once that change is made, and you try to import pylab, you should get a
RunTimeError telling you that matplotlib can't create the directory, either
because the path doesnt exist, or it exists but you cant write to it. At that
point you can set your MPLCONFIGDIR environment variable to point somewhere
writeable, and if it seems like a bug that matplotlib is trying to create a
directory somewhere nonsensical, please let us know.

The following should be on one line:
svn co
https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib
matplotlib
then cd into the new directory and install in the usual way.

This is the crucial bit.
Looks like you've set MPLCONFIGDIR to a read-only dir, or the
.matplotlib in the current dir or .matplotlib in your home directory
aren't writeable by the user running your python script. (I'm doing a
bit of guesswork here...)
What is it that you're trying to do?
cheers,
Chris

This bug was first pointed out by Mark Hamilton (with a patch) in the
thread "RuntimeError in _get_configdir". I've committed his fix to
svn. Basically, the format string is looking for two arguments where
only one is provided. Because it only arises in an error condition,
it is a corner of the code that had not been hit before.

We might be in a better position to help if you post the example code.

[Matplotlib-users] Runtime Error on running matplotlib examples pythonic_matplotlib.py, cursor_demo.py, etc .. (Pythonwin 2.4 crashes)
Hi Guys, I'm a new user of Matplotlib and am very impressed by its plotting capabilities. I have the latest version of Matplotlib and Numpy 1.0 running on my Win 2000 system with Python 2.4. On running the pythonic_matplotlib.py,cursor_demo.py etc.. in Matplotlib examples in the Pythonwin interpreter, the program runs fine, the tk window shows up and when I close the window by way of the 'x' on the right hand side, it closes fine. But however, when I reload pythonic_matplotlib.py, and run it again (by pressing F5), the tk window shows up, but the all the functions on the toolbar do not work. When I press the 'x' on the right hand side of the window, it shows the following message and Pythonwin crashes. "Runtime Error! Program: c:\Python24\Lib\site-packages\pythonwin\pythonwin.exe This application has requested the Runtime to terminate in an unusual way. Please contact the application's support team for more information" I was wondering what the issue could be. Your response is greatly appreciated. Thanks. Maser - Cheap Talk? Check out Yahoo!
