General :: When Type"import WxPython" In "python Environment It Returns?
Jan 26, 2011
I have installed wxPython on my Ubuntu 9.10. But when I type"import wxPython" in "python environment it returns the followingerror.Does it need a PATH to be added in ".bashrc"? If so what should I write as a PATH for it?
>>> import wxPython
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
create a tar file from a list? My script returns the error: AttributeError: 'list' object has no attribute 'startswith' I want to create a compressed tar file containing the directory /usr/lib and the files in the list assigned to variable b.
code:
import tarfile tar = tarfile.open("backup.gz", "w:gz")
The system is Debian Squeeze/Sid with apt.conf set to Squeeze as the default. Most packages are from Squeeze.
I ran apt-get upgrade and it returned an error-code.
It might be it is this bug: Bug#574153: python-pkg-resources: Missing file leaves it unconfigured
I tried aptitude install -f, to hold it and to remove the package python-pkg-resources, but i am getting told the package would be in a very bad stage, and i should re-install it. That doesn't work.
I'm trying to compile Ardour on jessie amd64 using the Debian source code (there's already an ardour package but I want to use different compile options). I've applied the Debian patches and have all the required dependencies installed.
Scons quits with a KeyError message from python2.7 saying that os.environ['DEB_HOST_ARCH_OS'] is not defined.
Checking with 'dpkg-archtecture -l' shows that DEB_HOST_ARCH_OS=linux, but 'print os.environ["DEB_HOST_ARCH_OS"]' in python says that name 'os' is not defined. The scons script has 'import os' at the top so it should be seeing it.
How do I make this visible to python (I'm assuming this problem is specific to the jessie python2.7 installation and not python in general)?
I have installed wxPython on my Ubuntu 9.10. But when I type "import wxPython" in "python environment it returns the following error.It tries to run the previously installed one not the new one. (The new version is 2.6).Does it need a PATH to be added in ".bashrc"? If so what should I write as a PATH for it?
in ubuntu 10.10, I have installed python 2.7. I would like to use apt-get to install packages to this version of python but I haven't been able to figure out howThings I have tried without success:changing the symlink at /usr/bin/python to point to /usr/bin/python2.7 - even after doing this apt-get still installs stuff to python2.6.Set up python2.7 as the primary alternative using update-alternatives - doesn't work
I've recently upgraded to natty narwhal and made a clean install of many programs. For the most part, only a few programs needed any real fixing. Editra, however, does not seem to launch, and it looks to be a wxpython error:
Code: Traceback (most recent call last): File "/usr/bin/editra", line 79, in <module> main() File "/usr/bin/editra", line 74, in main import Editra File "/usr/local/lib/python2.7/dist-packages/Editra/src/Editra.py", line 59, in <module> import profiler .....
I'm have the latest version of wxpython, python setuptools, and editra itself.
i assumed :i insert mode would allow to simply back space, no appearently not? it seems none of the websites anywhere on earth mention how to delete a carriage return in vi.
I use the time command to measure the wall-clock time of a GPU implementation of an algorithm. When I time the CPU execution of the algorithm time returns a negligible sys time. However, when I time the GPU execution time returns a sys time that is around 20-30% of the total time. If that time was comparable with the negligible sys time of the CPU I would achieve a speedup of a few times higher.
I suspect that the increased sys time is because of the GPU usage, which, I assume, takes some time for the OS because of the drivers etc. I am not sure though, and it is important to figure this out because it will improve my results a lot if I can ignore the sys time and use just the user time for speedup calculations. Also, is there a way to see, in detail, what is the sys running and takes so much time. I am thinking that I might be able to see if it is the driver indeed that causes this delay.
I have this issue: "nc -v <ip-address> 22" works fine, but "nc -v <fqdn> 22" fails with error message "nc: getaddrinfo: Name or service not known". However, "host <fqdn>" works fine, so name resolution works. So I have a working name resolution, but nc (netcat) doesn't seems to be using it or something. Same kind of issue with "ping <fqdn>". Does anyone know how come name resolution works, but utilities such as nc and ping doesn't?
First time here at LQ, so if the post is in the wrong place, this is a bit programming related. I've been trying to find the maximum resident memory of a process in a memory constraint situation.
Instead of using top, or ps, which gives me real-time snapshot at the memory usage of a process, is there a way to determine the maximum resident memory used by a process? /usr/bin/time seem to provide this functionality within the format string
[Code]...
The minor page-fault is suspicious, does that mean memory is being used.. but not recorded? if so, how can I know how much memory is being mapped?
I want to use ssh to execute a command and to wait endlessly to log everything (in file) that comes as a stream of the connected server. But unfortunately, in the manual its written "If command is specified, it is executed on the remote host instead of a login shell"
So what happens is that when I specify my command: ssh user@server "my_command"
It executed the command and the flow of execution returns to bash shell. So basically my session ends right after the command is executed. This happens only in case I specify command in the command line. If I login into ssh manually and then type "my_command", then the session doesn't end. I want the ssh not to exit, because after "my_command" executes, I want to capture everything in the session.
I am a Windows 7 user. I have two machines a laptop & a new bench top. Both machines run & boot Windows 7 very well. I use a very good program to clone my Hard Drive to an external USB drive. called Macrium Reflect. It is free and is a dream to use & very fast. This program creates a Linux based boot disk, which will allow you to find a backup clone file on an external drive to restore your hard drive. It works a treat on my laptop & has saved my bacon many times when I have messed things up fiddling with the registry etc.
The problem I am having is that my new desktop will not boot from the start up CD & returns the error kernel panic,not syncing cpu context corrupt. & then just tries to reboot again. I don't know what this problem relates to whether it is the computer hardware or the Linux CD or both. My laptop with the same OS does not have a problem, It is an Acer Aspire 5920G with 1.6ghz Intel dual core processor & 2gig Ram. The bench top has an Intel Dual core 3.3ghz processor, Zotac mother board & 4gig of Ram. both machines are running 32 bit OS.
I have browsed through the posts on this forum with people having the same error at boot, but as I am not using Linux & only using a boot CD I didn't think it appropriate to but into their threads. So I am hoping if some one can tell me is this a hardware issue or a Linux/New dual core CPU/ or Bios/Mother board issue. If it is a Linux issue then my Laptop surely would not boot would it? My bench top is only a week old and guaranteed, should I be sending it from Adelaide back to Sydney(purchased online from MWave) for fault inspection? or just take to a local Technician for a diagnosis. I am not having any hardware problem running Windows 7.
I would like to install wxpython2.8 for python2.5, which I installed as an alternative version in the presence of the standard python2.6 using xubuntu 10.04 lucid lynx (see the end of this thread for how I did it).how would I do this without the installation going for the standard 2.6 version? I found some notes to that on the web:

I tried those, but somehow my wxpython installation got borked and would not do anything afterwards.
I have a function definition in a Python 2.x script which take a tuple as one of its arguments, but 2to3 has no answers nor any of my searching on how to represent the same in Python 3.x
Due to this problem, everything that uses python is not working.
