Cannot install Pypvm (Python Parallel Virtual Machine)   (131 Views)
. I am trying to install Pypvm (, the Python interface to PVM ("Parallel Virtual Machine"). Unfortunately, installation fails. I am hoping someone can help me fix it. I am running Fedora Core 8 Linux. The official Pypvm documentation is very helpful (or something), providing the following: To build Pypvm, cross your fingers and try: make -f boot make Or alternatively, try python build python install For me, the "make -f boot" seems to run fine, but the "make" fails, giving (among other things) the following: [ore@localhost pypvm-0.94]$ make gcc -pthread -fPIC -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 - march=i386 -mtune=generic -fasynchronous-unwind-tables -D_GNU_SOURCE -fPIC -I/usr/include/python2.5 -I/usr/lib/python2.5/config -c ././pypvm_coremodule.c -o ./pypvm_coremodule.o ././pypvm_coremodule.c:2:18: error: pvm3.h: No such file or directory ././pypvm_coremodule.c: In function was_error: ././pypvm_coremodule.c:81: error: PvmOk undeclared (first use in this function) ././pypvm_coremodule.c:81: error: (Each undeclared identifier is reported only once ././pypvm_coremodule.c:81: error: for each function it appears in.) ././pypvm_coremodule.c:85: error: PvmBadParam undeclared (first use in this function) ././pypvm_coremodule.c:85: error: PvmMismatch undeclared (first use in this function) [...] ././pypvm_coremodule.c:1889: error: PvmDupEntry undeclared (first use in this function) ././pypvm_coremodule.c:1767: warning: unused variable optModule ././pypvm_coremodule.c:1766: warning: unused variable resultModule ././pypvm_coremodule.c:1765: warning: unused variable notifyModule ././pypvm_coremodule.c:1764: warning: unused variable spawnModule ././pypvm_coremodule.c:1763: warning: unused variable dataModule ././pypvm_coremodule.c:1762: warning: unused variable exceptionModule make: *** [pypvm_coremodule.o] Error 1 [ore@localhost pypvm-0.94]$ In in alternate version, "python build" similarly fails: [ore@localhost pypvm-0.94]$ python build running build running build_py running build_ext building 'pypvm_core' extension gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall -Wp,- D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer- size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables - D_GNU_SOURCE -fPIC -fPIC -I/usr/include -I/usr/include/python2.5 -c pypvm_coremodule.c -o build/temp.linux-i686-2.5/pypvm_coremodule.o pypvm_coremodule.c:2:18: error: pvm3.h: No such file or directory pypvm_coremodule.c: In function was_error: pypvm_coremodule.c:81: error: PvmOk undeclared (first use in this function) pypvm_coremodule.c:81: error: (Each undeclared identifier is reported only once pypvm_coremodule.c:81: error: for each function it appears in.) pypvm_coremodule.c:85: error: PvmBadParam undeclared (first use in this function) [...] pypvm_coremodule.c:1889: error: PvmDupEntry undeclared (first use in this function) pypvm_coremodule.c:1767: warning: unused variable optModule pypvm_coremodule.c:1766: warning: unused variable resultModule pypvm_coremodule.c:1765: warning: unused variable notifyModule pypvm_coremodule.c:1764: warning: unused variable spawnModule pypvm_coremodule.c:1763: warning: unused variable dataModule pypvm_coremodule.c:1762: warning: unused variable exceptionModule error: command 'gcc' failed with exit status 1 [ore@localhost pypvm-0.94]$ Can anyone help me get it to work

Cannot catch _mysql_exceptions.OperationalError   (163 Views)
In our database code (we are using django v0.96) we wanted to catch and handle MySQL OperationalErrors. We use both the Django models and database connections. However, even though we confirmed that a _mysql_exceptions.OperationalError are raised (particularly 1213 deadlock), we cannot catch them with try/except. Here's the code that did not work: import _mysql_exceptions from _mysql_exceptions import OperationalError try: database_code() except (_mysql_exceptions.OperationalError, OperationalError), e: error_handling() Originally, we just had one import, but tried both to ensure that was not the problem. In debugging, we confirmed that both type(e) and e.__class_ were . The only work-around we found was: try: database_code() except Exception, e: if e.__class__.__name__.find('OperationalError') != -1: error_handling() else: raise This seems silly. If we used any other exception, the except clause seems to work correctly. Is there a problem with _mysql_exceptions.OperationalError Is there a better work-around

For now it would probably be best to start by posting your questions on the regular comp.lang.python group, which is generally suitable for beginners who know something about programming. If you are new to programming as well then the python-tutor list would be more useful.

Tabnanny errors when Migrating Python 2.4 code to 2.5   (171 Views)
When Python 2.5 first came out, I eagerly downloaded it and immediately had issues with getting it to run my 2.4 code. So I just stuck to 2.4. However, I decided this week that I really should try to get 2.5 to work. Does anyone know why code that works perfectly for months in a 2.4 environment throws indentation errors in 2.5 And why does 2.5 default to indenting 8 characters instead of 4 in IDLE That's just weird. When I did a select all and did a Tabify region, it indented everything 8 characters then too. I haven't changed the configuration at all. Any ideas
Cannot understand error message   (135 Views)
The following code produces an error message (using Idle with Py 2.4 and 2.5). "There's an error in your program: EOL while scanning single-quoted string". It comes just after "s = ''" (put there to try and isolate the broken string). It would be good if the error message pointed me to the start of said single quoted string. The colouring in IDLE does not indicate a bad string. Puzzled. Bill # # The traceback module is used to provide a stack trace to # show the user where the error occured.

Just hand in the result of urlopen(). Apart from that, I saw that you found your way to the lxml mailing list, I'll respond over there.

PIL Error: "cannot read interlaced PNG files"   (147 Views)
There, I'm developing an application that lets the user to upload JPG and PNG files. I'm using PIL to check the images after the upload (like checking it storage size, width and height). But PIL raises an error: "cannot read interlaced PNG files" It says that interlaced PNG files are not supported in the PIL documentation. I'm using PIL 1.1.6-2 on Arch Linux.. I can check all images with: from PIL import Image im ='image.png') which returns a dictionary about the image. If the dict has 'interlace' key with the value 1, then I reject the event that's being send with a validation error. But I don't think this is a good idea since this could be very annoying for the users.
cannot declare global vars!   (169 Views)
i had posted earlier for not being able to declare global vars. No i followed the suggestions and created a class, but still the vars do not seem to have a global scope.

Greetings, Could someone point my muddled head at a/the python repository. I know that one exists but cannot find it again. In particular I am looking for a standalone search tool that given a path searches files for a text string.
Calling Usergroup Organizers (and Wannabees)   (160 Views)
We'd like to strengthen and raise the visibility of Python usergroups and foster the creation of new ones, by sharing the valuable experiences of those leaders around the community who make it happen. [1] One step is to make others more aware of what is already happening, perhaps in their own neighborhood re Python meetings. I've created a shared blog and invite organizers of existing groups to send me their email address to get privs to post to it. Because these postings will be distributed far and wide, a posting should be of interest to those who did not attend but are considering doing so, or that might be instructive to organizers in other cities. An overview of what was covered in a past meeting, or an announcement with substance on what an upcoming meeting is going to be about are good postings. A simple date and local address, or that the pizza was good last week, is not. ;-) [2] A second step is to encourage and support new organizers in forming groups in their area. There is a strong demand for such meetings, but many are uncertain how to go about it. Therefore I've created a new mailing list on which experienced and new organizers can share tips on getting started, whether about getting the word out, finding a place to meet or getting interesting speakers. Those of us with a history of involvement in a usergroup often forget that many people have never attended a usergroup meeting, or lack experience in running one, so let's help strengthen this aspect of Python. We could use some videos or photos of group meetings as well, posted to and the link emailed to me for use. I'd also like to reach out to the existing, successful usergroups and ask them to spread the word about their efforts by being interviewed by Ron Stephens on Python411, and/or writing up an article on how your group got started for Tennessee Leeuwenburg of _The Python Papers_. Even a simple "what a typical meeting is like in my area" is helpful. It would be especially interesting to see how usergroups operate in various countries around the world, and perhaps help bring together these regions. In closing, please, for existing usergroups as well as new ones coming online, update the entry for your group on the roster of Python usergroups. Jeff Rush Advocacy Coordinator
PyCon: talks and tutorials announced   (164 Views)
The slate of talks and tutorials for PyCon 2007 is now public. Talks: Tutorials: A first draft of the schedule is at . Caution: This schedule is still subject to change -- speakers may report conflicts that will require some rearrangement, and session times may still shift around a little. Be especially cautious if you're selecting what time to leave on Sunday; if the Sunday afternoon talks are shuffled, you might have to miss an interesting session. Note that the schedule has three -- count' em, *three* lightning talk sessions, so if you want to give a five-minute talk about a project or idea, there's lots of room available. See for more information. Andrew M. Kuchling Co-chair, PyCon 2007 Jeff Rush Co-chair, PyCon 2007
