I have tried to run an Python program in my Opensuse OS this Program used libnet and pcap.
import queue
import sys
import socket
import libnet
from libnet.constants import *
import pcap
I have installed libnet-devel but when i run the program i recieve the folowing message.
Traceback (most recent call last):
File "example.py", line 9, in <module>
import libnet
ImportError: No module named libnet
I have tried with different Python version, How can i solve this Problem?
using the system python (the one in /usr/bin/python):
make sure that python-pip is installed via yast
download pylibnet from http://sourceforge.net/projects/pylibnet/
install pylibnet with the command
sudo pip install ./pylibnet-3.0-beta-rc1.tar.gz
there does not seem to be a version of pylibnet packaged and available through yast, which is why you need to install one using pip (which is a program for installing python packages).
libnet-devel only installs the c library - the above installs the python library.
[edit: forgot the "install" in the pip command; added download instructions]

I'm using python 2.7.18 on Windows, and i saw that ipaddress library was exclusively for python3 so i installed py2-ipaddress using pip. When i ran pip list into cmd, it shows py2-ipaddress as installed, but when i try import ipaddress into a python file i get this
Traceback (most recent call last):
File "C:/Users/x/Downloads/main (2).py", line 1, in <module>
import ipaddress
ImportError: No module named ipaddress
Why i can't import it?
EDIT :
Actually, ipaddress works fine on python2.7.x, or it should, i installed now ipaddress using pip install ipaddress, it shows as installed when running pip show ipaddress but i still can't import it
#Matthias was right. It seems that my pip doesn't work properly, or i don't know how to use it properly. One quick fix, if you're running pycharm or any IDE with a built-in terminal is to install the module via IDE's terminal using pip install <module>.
when I request using "playsound" library for Python to play the audio
file .mp3 it returns me the following error:
Code:
import playsound
playsound.playsound("test.mp3")
Error:

import gi
ModuleNotFoundError: No module named 'gi'
The most simple way is the vext approach.
pip install vext
pip install vext.gi

How do I install python3-gi within virtualenv?
It seems like you are using an anaconda environment. I also faced this issue and fixed it by doing the following:
First, create a symlink to gi module in your system Python. For me, the command is as follows:
ln -s /usr/lib/python3/dist-packages/gi/ /home/USERNAME/miniconda3/lib/python3.7/site-packages/
Then, open the directory:
cd /home/USERNAME/miniconda3/lib/python3.7/site-packages/gi/
and run the following commands:
sudo cp _gi.cpython-35m-x86_64-linux-gnu.so _gi.cpython-37m-x86_64-linux-gnu.so
sudo cp _gi_cairo.cpython-35m-x86_64-linux-gnu.so _gi_cairo.cpython-37m-x86_64-linux-gnu.so
My system Python is 3.5 and miniconda Python is 3.7. Your versions may differ from mine, so take care of that in the commands above (-35m- and -37m-).

I tried to execute a program using geonames_rdf, but I cant execute it by this error:
Traceback (most recent call last):
File "geo1.py", line 13, in <module>
import geonames.config.log
ImportError: No module named config.log
I read several posts abot ImportError and I check the path of the system and it is correct. I'm working in a VirtualBox with a fresh Ubuntu 16.04.
The imports of my program are:
import sys
import os
import os.path
import logging
import geonames.config.log
import geonames.compat
import geonames.adapters.search
I've also tried add this line:
sys.path.append('/usr/local/lib/python2.7/dist-packages/geonames/')
The command that I used to instal this package was
sudo pip install geonames_rdf
Try appending site-packages not dist-packages. A bit of searching it looks like dist-packages is debian specific.
sys.path.append('/usr/local/lib/python2.7/site-packages/geonames/')
Reason:
Since you're installing 3rd party python package via pip it will not go into dist-packages and python rightfully cannot find it on the path.
Reference link:
What's the difference between dist-packages and site-packages?
I just tried to use geonames_rdf, but I didn't know I needed it to do a geonames search so I installed geonames first, then discovered I had to install fiona and gdal (I'm on Windows, had to install these two using prebuilt whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/). Don't know why these dependencies aren't baked into geonames.
Anyway once I then installed geonames_rdf it seemed to install into the geonames folder in c:\Python27\lib\site-packages, added at least the adapters package. In c:\Python27\lib\site-packages\geonames there is a config folder with log.py in it.
I just installed Gubbins using their homebrew instructions. Everything seemed to go smoothly and gubbins is now in /usr/local/Cellar/gubbins/1.1.1/bin/gubbins. I'm supposed to be able to use it by running their script run_gubbins.py and giving it an input file. But I get the following error:
>$ /usr/local/Cellar/gubbins/1.1.1/usr/bin/run_gubbins.py test.fasta
Traceback (most recent call last):
File "/usr/local/Cellar/gubbins/1.1.1/usr/bin/run_gubbins.py", line 25, in <module>
from gubbins import common
ImportError: No module named gubbins
Looking inside the run_gubbins.py script I see that the first things it does is
import sys
sys.path.append(".")
import argparse
from gubbins import common
So what might be happening? How come the script within a program package is not recognizing the program it came with? Is there anything I can do to fix this? Thank you so much.

Depending on which installation of Python I am using I have some problems to load a module. When I type
from quantecon import approx_markov
in the terminal using Python 3.4.0, the following error message is returned:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.4/dist-packages/quantecon/__init__.py", line 6,in <module>
from asset_pricing import AssetPrices
ImportError: No module named 'asset_pricing'
In the folder /usr/... as referred to above, I do however find a module called asset_pricing. (I have to admit that I additionally do not understand why the module asset_pricing interferes.)
I installed quantecon with:
pip3 install quantecon
I suspect that the problems are related to the Python version I am using. I also installed
pip install quantecon
and when I call the module approx_markov form the terminal, using Python 2.7.6 (I think this is the standard Python version of the OS I am using) I do not receive any error message. To solve the problem I already followed the instruction in the following discussion but to no avail Python3 has no acces to python2 modules (ubuntu).
The currently released version of quantecon is not Python 3 compatible; it uses relative imports and these are not supported anymore in Python 3.
The version in the source repository has been refactored and updated, and looks like it'll work with Python 3. You'll need to install that version instead:
pip3 install -U git+https://github.com/jstac/quant-econ.git
where -U tells pip3 to upgrade the package.
Note that there have been a lot of changes recently; use at your own risk. You could stick with Python 2 and wait for an official release.
