I have a running Python 2.7/3.4 installation on my Windows 7 (x64) machine. I would like to test curses on Windows.
Curses is installed but not working:
>>> import curses
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Tools\Python3.4.2\lib\curses\__init__.py", line 13, in <module>
from _curses import *
ImportError: No module named '_curses'
The documentation says:
The Windows version of Python doesn’t include the curses module. A ported version called UniCurses is available.
So, the Windows installer of Python 3.4 installed curses with unresolved dependencies. One could name this a bug...
OK, I looked into UniCurses. It's a wrapper for PDCurses:
UniCurses is a wrapper for Python 2.x/3.x that provides a unified set of Curses functions on all platforms (MS Windows, Linux, and Mac OS X) with syntax close to that of the original NCurses. To provide the Curses functionality on Microsoft Windows systems it wraps PDCurses.
Installing UniCurses via pip3 results in an error:
C:\Users\Paebbels>pip3 install UniCurses
Downloading/unpacking UniCurses
Could not find any downloads that satisfy the requirement UniCurses
Some externally hosted files were ignored (use --allow-external UniCurses to allow).
Cleaning up...
No distributions at all found for UniCurses
Storing debug log for failure in C:\Users\Paebbels\pip\pip.log
The link to SourceForge on Python's UniCurses site is dead. A manual search an SourceForge helped to find UniCurses for Python again.
But, the UniCurses 1.2 installer can not find any Python installation in my Windows registry. (Python 2.7.9 and Python 3.4.2 are available).
I also looked into Public Domain Curses (PDCurses). PD Cureses 3.4 is from late 2008. So it's 7 years old. I don't believe it will work either with Windows 7 nor Windows 8.1 or Windows 10.
Is there any way to get curses running on Windows with Python.
(The Windows Python, not the CygWin Python!)
You can use curses cross-platform (Windows, MacOS, GNU/Linux) if you install manually for Windows or like other package in others.
Install wheel package. If you need more info about wheel click here.
Go to this repository.
Download a package with your python version, in example for python 3.4:
curses-2.2-cp34-none-win_amd64.whl
Install it (this command if for windows, in GNU/Linux install like other package)
python -m pip install curses-2.2-cp34-none-win32.whl
Just include in your python script:
import curses
You can use curses wrapper for python. Works in Fedora 25 in all terminals, and Windows 10 using git bash, powershell, or cmd.
Update:
An alternative to curses in Windows here.
Console user interface in Windows here.
An interesting tutorial here.
Now we can easy install on python 3.7 using pip install windows-curses
You can try my mirror of unicurses, which includes pdcurses dlls. I have it currently up and running on windows 7 with python 3.5.0.
To quickly test if it works for you, just clone the repository and create and run a python script within its toplevel directory containing something like
from unicurses import *
stdscr = initscr()
addstr("hello world")
getch()

I tried to run this simple code, which is about GUI programming in python usinh Python GTK+ 3:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
win = Gtk.Window()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
I have anaconda 5.2 installed with Python 3.6 under Windows 10, and I get this error:
import gi
ImportError: No module named 'gi'
Even if I install anaconda 4.2 with Python 3.5 I get the same error.
I could not figure out how to install gi, which is apparently part of PyGObject.
using pip install PyGObject results in an error:
Failed building wheel for PyGObject
Can anybody help?
As I explain in this answer there are two ways (afaik) to install PyGObject in Windows.
If you use the .exe installer you'll be restricted to Python 3.4. I've never used it with Anaconda, but the installer (before automatically checking for Python interpreter installations) lets you select "portable" installations of the interpreter (I believe this might be the way to point to a virtual environment interpreter, maybe a conda installed interpreter, I've never used it though). You can try and let it try to find your interpreter automatically and if it doesn't then you can cancel the install and re try with the "portable" approach.
If you use MSYS2 I really don't know how you can make it work. You'll have to use the included pacman instead of Anaconda to manage your packages, so I don't know if this is what you want.
I am trying to install some python modules that are only for 2.x (like mechanize 'tried using pip, easy_install, even running the setup.py'). However, the modules are not showing up for me. I believe this is because I have a few versions of python installed for windows, and the default installation for the terminal is different than my PyCharm Project Interpreter:
My PyCharm project uses the project interpreter: 2.7.10 (C:\Python27\python.exe)
When I type into the terminal of PyCharm:
py -2.7
It calls this version: Enthought Canopy Python 2.7.9 | 64-bit | (default, Jul 1 2015, 03:41:50) [MSC v.1500 64 bit (AMD64)] on win32
However, I have a version of python that is 2.7.10. If I call
py -2.7.10
I get: Unknown Option: -2
Did my path for python 2.7.10 get written over by Enthought Canopy Python 2.7.9? How do I change my terminal python so I can install the appropriate files to run my PyCharm project with project interpreter: 2.7.10 (C:\Python27\python.exe)?
Thank you
The best way to go about going this would be to create a virtual environment (called virtualenv). This is the best link to get you started
Otherwise, open PyCharm, File>>Default Settings>>Project Interpreter>>Select the Interpreter you want to install the packages to, press the red '+' sign to the right, search the package and install.
I have installed git-cola using the setup installer for windows. I pointed it to proper installs of git and python.
When I try to launch git-cola, nothing happens whatsoever.
Is there something I am missing here?
I had the same problem, in my case it was missing PyQt4 library. You can install PyQt4 by downloading an appropriate installer from Binary Packages section on PyQt4 Riverbank website.
How I investigated the issue
When I installed git-cola in a default directory and tried to run it using a command line
C:\Program Files (x86)\git-cola\bin>python git-cola.pyw
I got
Sorry, you do not seem to have PyQt4 installed.
Please install it before using git-cola.
e.g.: sudo apt-get install python-qt4
Note
I have two Python 2.7 installations, one at c:\program\Python27 and another at C:\Users\UserName\Anaconda2, I used the first one. I also installed Python SIP some time ago, I'm not sure if it required by git-cola.
I have the python package in Cygwin on Windows 7. However, typing
python -V
returns
Python 2.6.8
This is a pretty low version of Python... I could use Python 3.x (whatever version is newest, preferably). I've seen some people say you have to download a .zip or .tar manually to get it (similar to this question). My questions are as follows (please note this is NOT a duplicate of the linked question):
Can I get Python 3.x somehow using the Cygwin package manager?
Can/should I get rid of Python 2.6 if I manage to get Python 3.x running? None of my code runs on anything specific to Python 2.6.
Thanks
As others have noted, the version of Python 2.6 that's installed with Cygwin is recent; Python release numbers are not linear with respect to time. The Python releases page details which versions were released on which date.
You can install Python3 if you want, using Cygwin Ports. This is a collection of Cygwin packages that are not ready for general release on the main Cygwin mirrors, but have been compiled ready to be used on Cygwin. I've written some instructions over on SuperUser which describe in more detail how to do this.
(I'd avoid installing from source, as Lennart suggests, as I'd expect this will require non-trivial fixes to make it work on Cygwin.)
As noted in the above-linked SuperUser question, there's no need to uninstall Python 2.6 to install Python 3; the two run happily side-by-side.
That said, beware your claim that "None of my code runs on anything specific to Python 2.6": Python 3.x is not back compatible with Python 2.x, and code written for Python 2.x will generally not work on Python 3.x without work to adapt it. The Python 3.0.1 What's New Guide has a good overview of the changes in Python 3.x.
Update: As of Wed 25 July 2012, Python 3.2.3 is included in the standard Cygwin installer. Just run Cygwin's setup.exe again (download it from cygwin.com again if you need to), and you should be able to select and install it like any other package.
am trying desperately to get OpenCV to work on Windows 7. I download and installed it, and it didn't work, I got
ImportError: No module named opencv
when I tried to run one of the samples. I google my problem and got only random solutions that don't work. Can anybody guide me in installing it, or know where i can get a clear installation guide design for a programming noob.
As of OpenCV 2.2.0, the package name for the Python bindings is "cv".The old bindings named "opencv" are not maintained any longer. You might have to adjust your code. See http://opencv.willowgarage.com/wiki/PythonInterface.
The official OpenCV installer does not install the Python bindings into your Python directory. There should be a Python2.7 directory inside your OpenCV 2.2.0 installation directory. Copy the whole Lib folder from OpenCV\Python2.7\ to C:\Python27\ and make sure your OpenCV\bin directory is in the Windows DLL search path.
Alternatively use the opencv-python installers at http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv.
I have posted a very simple method to install OpenCV 2.4 for Python in Windows here : Install OpenCV in Windows for Python
It is just as simple as copy and paste. Hope it will be useful for future viewers.
Download Python, Numpy, OpenCV from their official sites.
Extract OpenCV (will be extracted to a folder opencv)
Copy ..\opencv\build\python\x86\2.7\cv2.pyd
Paste it in C:\Python27\Lib\site-packages
Open Python IDLE or terminal, and type
>>> import cv2
If no errors shown, it is OK.
UPDATE (Thanks to dana for this info):
If you are using the VideoCapture feature, you must copy opencv_ffmpeg.dll into your path as well. See: https://stackoverflow.com/a/11703998/1134940
I have posted an entry to setup OpenCV for Python in Windows:
http://luugiathuy.com/2011/02/setup-opencv-for-python/
Hope it helps.
Actually you can use x64 and Python 2.7. This is just not delivered in the standard OpenCV installer. If you build the libraries from the source (http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html) or you use the opencv-python from cgohlke's comment, it works just fine.
download the opencv 2.2 version from https://sourceforge.net/projects/opencvlibrary/files/opencv-win/
install package.
then Copy cv2.pyd to C:/Python27/lib/site-packeges.
and it should work:
import cv2
open command prompt and run the following commands (assuming python 2.7):
cd c:\Python27\scripts\
pip install opencv-python
the above works for me for python 2.7 on windows 10 64 bit
One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.
That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'
