Python 2.7.6 ImportError: No module named opencv - python

I installed opencv using brew and it seemed to install fine. I installed numpy, Scipy and Matplotlib with no problems. I run python and import these modules with no error. But opencv has been a real pain in the neck. I've spent hours try to get this to work.

ImportError: No module named opencv
It almost seems like homebrew did not put the opencv module in the right directory.

the module is not named opencv, but cv2, so :
>>> import cv2
>>> cv2.getBuildInformation()
[EDIT]
if you're trying to run something like this ,
then there's bad news for you. opencv comes with it's own python bindings since a very long time now, but apart from that, there exist several outdated 3rd party bindings. the code you're trying to run seems to use one of those, so you can't use it with opencv's builtin api.

How to install tkinter for python3.10.6 on CentOS7?

First, I installed openssl 1.1.1q package using the following source on CentOS7.
(https://www.openssl.org/source/openssl-1.1.1q.tar.gz)
Second, I installed tcl/tk packages using the following sources.
(https://prdownloads.sourceforge.net/tcl/tcl8.6.12-src.tar.gz
https://prdownloads.sourceforge.net/tcl/tk8.6.12-src.tar.gz)
Finally, I installed python 3.10.6 using the following source.
(https://www.python.org/ftp/python/3.10.6/Python-3.10.6.tar.xz)
However, I can't use tkinter module.
For example, when I import tkinter I get the bellow message.

The yum doesn't support the python 3.10.x version. How can I resolve this problem without yum?
What should I do to use tkinter?
You are importing tkinter in a wrong way, it is like this
import tkinter
tkinter is a preinstalled library in python, to test it open cmd and type
python -m tkinter
a small window should appear, if it does then it is working

How to import a package that use absolute import in python

I'm trying to import volatility3 into my python project/script, so that I don't have to use os.system since volatility3 is already made in python3.
I'm wondering how can I import all the functions/modules of said project ? The functions I'm interested in are located in volatility3/volatility/framework
I tried simply putting:
>>> import volatility3.volatility.framework
But I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/volatility3/volatility/framework/__init__.py", line 12, in <module>
from volatility.framework import constants, interfaces
ModuleNotFoundError: No module named 'volatility'
My guess is I have to modify sys.path or one of the path variables but this does not seem to work.
Thanks,
The best solution here would be to properly install volatility with pip3, from your already exiting repository folder:
$ pip3 install /home/volatility3
or directly from pipy (not tested):
$ pip3 install volatility3
then you should be able to import the from volatility package directly:

salesforce python Beatbox import error

I am trying to log in to salesforce.com's sandbox using a URL, ID and PASS. I want to use SOAP API for that. When I try to import beatbox in python3, it throws an ImportError exception. However, I can confirm that beatbox is installed in python3. So what am I doing wrong? Is there any other way to do it?

ImportError: No module named '_beatbox'
>>>
The beatbox module that you probably installed is this : Beatbox 32.1.
Solution 1 : The above beatbox module only supports python 2.x (tested with python 2.7). So, switch to Python 2.x if that is an option.
You can find the source by original author of beatbox here and it has been updated to support python3.
Solution 2 :
Clone the repo in your local machine using git clone https://github.com/superfell/Beatbox.git
Change to the Beatbox directory
Install the module using python setup.py install
For me the issue was I had both beatbox and beatbox3 installed.
beatbox3 is the version for python3.
Once I uninstalled beatbox it worked fine.

from pylab import plot

I have installed python 3.5 on a computer running Scientific Linux 6.5. I have set up a virtual environment, and I have installed numpy and pylab using pip version 8.1.2.
My problem is this, when I try to do the simplest of tasks, i.e. import plot from pylab, I get this:
$ python
Python 3.5.1 (default, May 10 2016, 12:41:42)

Here is some other information:
>>> pylab.__version__

>>> matplotlib.__version__
'1.5.1'
>>>
I don't find any help through Google, and the only question similar to this doesn't seem relevant to me. What is going on?
After coming back over a weekend break and trying again with iPython, I got a different error message, which led to another Google search...
I found the answer here: Pylab - 'module' object has no attribute 'Figure'
My mistake was to think that pip install pylab would work as expected!
Installing pylab installs matplotlib, which apparently also installs pylab. This recursion causes the error. For me, uninstalling pylab and matplotlib and re-installing matplotlib alone fixed the error. I hope this helps!

PyQt4 can't import Qsci

I'm installing PyQt4 on an old Linux system (CentOS 4.4) that can't be upgraded for hardware compatibility reasons. I've got Python 2.6, QT4 and SIP installed, and the installation of PyQt4 didn't give me any errors.
When I run Python, this happens:
Python 2.6.2 (r262:71600, May 11 2011, 14:18:37)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt4
>>> import PyQt4.Qsci
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named Qsci
I looked around, and found /usr/local/lib/python2.6/site-packages/PyQt4/uic/widget-plugins/qscintilla.py, which is almost empty of non-comment stuff:
pluginType = MODULE
def moduleInformation():
return "PyQt4.Qsci", ("QsciScintilla", )
Any ideas?
You need to install qscintilla separately. If PyQt is already installed, then you should just have to install the qscintilla python bindings. Hopefully this fixes your issue!
