I've been trying to install PyGame with little success. I downloaded the
pygame-1.9.1release-python.org-32bit-py2.7-macosx10.3.dmg
version of PyGame from this link and installed it using the wizard, but when I typed import pygame into the IDLE I got the following message.
$ import pygame
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pygame
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/__init__.py", line 95, in <module>
from pygame.base import *
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/base.so, 2): no suitable image found. Did find:
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/base.so: no matching architecture in universal wrapper
What did I do wrong?
Also, what are the prerequisites for PyGame? I'm doing all this on a new computer and I've hardly downloaded anything.
I'm running OS X Version 10.8.2.
I know this thread is a little old, but thought I'd share my experience on this subject...
I'm using a 64-bit MacBook Pro running OS Mavericks and python 2.7.
Steps:
If you've installed a few different versions of pygame while trying to get the darn thing to import and work successfully, make sure you delete/uninstall all of these to get a fresh start. I did a simple search in the terminal to see where all of the various pygame folders where located:
In Terminal: sudo find / -iname "pygame"
The results show a list of all the pygame directories, these are the folders that you want to delete. Note, I created a new tab in terminal to do this so I can reference the directories from the search on the previous tab and easily copy each directory without having to do another search to remember where they are:
In Terminal: sudo rm -R -i path/pygame
Also note, you can take the -i out of the above code and it won't confirm the deletion of certain files, but BE REALLY CAREFUL when deleting full directories from the terminal.
Once your machine is clean of all previous pygame installations, make sure you have python 2.7 from python.org, NOT IDLE (default Mac Python Interpreter)! This is very important. I use PyCharm and it rocks! Also, choose the version that works on a 32-bit machine and 64-bit machine - this way you won't have issues with the pygame 32-bit installer on your 64-bit machine. I tried same installation process but with the 64-bit only python 2.7 installation and it didn't work. Link provided below:
Download 32/64-bit Python 2.7
Next, download the 32-bit pygame file for OS X 10.3 and beyond and run the mpkg file created from the dmg. Link provided below.
Download pygame 1.910 release for python 2.7
You should now have a working pygame installation in your python 2.7 package library. Enjoy.
Did you install python from python.org? Or use the one that came with OS X?
If you used the one supplied by Apple, you must download the one from python.org first, then install using that package. Or you can try the Lion-pygame package (the link is at the bottom of the Macintosh section of the download page), but it may be incompatible.
Did you download python 64-bit or python 32-bit?
This can cause major problems if you don't have the right one, if you have 64-bit you can download pygame 64-bit from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame

I cannot get autocomplete working for OpenCV (Python) on Windows.
According to Abid's instructions here, I pasted the cv2.pyd file in the C:\Python27\Lib\site-packages.
In the Python code, I import as follows:
import cv2.cv as cv
I have also installed numpy, and it created its own folder in site-packages unlike OpenCV (which I've pasted directly into site-packages).
With this setup, the code executes without any problems, even when OpenCV methods are called.
But I have not been able to get autocomplete to work. I have tried to get it to work on Sublime Text 2 (with SublimeCodeIntel) and PyCharm. In both IDEs, autocomplete works for the numpy import, but fails for the OpenCV import.
I'm using OpenCV 2.4.6, and Python 2.7 (32 bit).
Any possible solutions?
The reason it's not working is because you're using a .pyd file, which is essentially the same as a compiled .dll. Autocomplete works by reading the source .py files, which are plain text. Try installing the OpenCV and Intel Math Kernel Library optimized NumPy packages from Christoph Gohlke's Python Extension Packages for Windows repository, which is frequently updated and a must-use resource for anyone who does any kind of scientific Python computing on Windows. Make sure you delete the cv2.pyd and numpy directories from site-packages first. These new packages will install the .py source files needed by the autocomplete engine in Sublime Text.
EDIT
OK, so I wrote the above because it worked well for a bunch of other packages. I'm a Python 3 guy, and I never installed OpenCV from Gohlke because it only has Python 2 bindings. After reading #CrazyCoder's comment below, I booted up Win7, and indeed he's absolutely correct (and I should have realized this before) - since OpenCV is written in C/C++, the only .py file included in the Gohlke package is cv.py, whose entire contents are as follows:
from cv2.cv import *
The rest is contained in cv2.pyd and a bunch of .dlls. The full OpenCV Windows distribution from opencv.org is a 291 MB download, which expands to 3 GB, and the few .py files in there are involved in building OpenCV, and aren't any good for autocomplete purposes. So, unfortunately, I don't know if there's a solution to your problem at the moment. Just keep the docs handy, and perhaps check out OpenCV Computer Vision with Python from Packt/O'Reilly, published in April 2013.
I've had the same issue with PyCharm when building a custom version of OpenCV on windows. Here is what I did to fix it:
OpenCV made a folder in Python site-packages like so:
opencv site-packages
So what you need to do is just add the python-3.9 folder to your interpreter.
File
Settings...
Python interpreter
Three dots icon next to your interpreter -> Show all...
Select your interpreter and click on the "Show paths for selected interpreter" icon
Add the folder inside the cv2 site-packages
Now import the cv2 module normally.
The best way to solve all the problems of OPENCV-PYTHON is by uninstalling it and reinstalling it.
Even I faced the same problem.
I fixed it by:
python -m pip uninstall Opencv-python
Then I reinstalled it by using a lower version. But unfortunately, I did not know the versions of opencv; So by using a small trick you can get it by running:
python -m pip install opencv-python==
and you will get an error similar to this:
ERROR: Could not find a version that satisfies the requirement opencv-python== (from versions: 3.4.0.14, 3.4.10.37, 3.4.11.39, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 3.4.15.55, 3.4.16.57, 3.4.16.59, 3.4.17.61, 3.4.17.63, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.3.56, 4.5.4.58, 4.5.4.60, 4.5.5.62, 4.5.5.64) ERROR: No matching distribution found for opencv-python==
Here you can see all the versions of opencv-python; choose any one (but not the latest as the error occurs due the latest version of opencv-python. install it by using:
pip install opencv-python==3.4.17.61 (You can choose your version, but this version solved the issue for me)
then enjoy your coding....
Even AUTO-COMPLETE error in opencv-python gets solved.
HAPPY CODING
I`m having some issues installing Pygame. I am running a 64 bit Windows 8 system, with a 32 bit version of Python 3.4.
Here is how I have been trying to install it so far:
I have visited http://pygame.org/download.shtml and downloaded the file called pygame-1.9.2a0.win32-py3.2.msi.
I have executed the file and selected 'Install for all users'.
At this point it asks me to select a Python location into which I should install Pygame. I then select 'Will be installed on local hard drive' from the dropdown. A text box asks me to input an alternate Python location. This is set to C:\PythonX. I set it to my Python location - C:\Python34.
I finish the installer and go to the shell. I input import pygame into the command line. It gives the following error:
Traceback (most recent call last): File "", line 1, in
import pygame File "C:\Python34\lib\site-packages\pygame__init__.py", line 95, in
from pygame.base import * ImportError: DLL load failed: The specified module could not be found.
If I look in the Python34 file after the install, I find the Pygame folder in the location C:\Python34\Lib\site-packages\pygame.
Any help would be greatly appreciated.
Installing from MSI and not pip make sure you get the correct version that matches your set up of Python.
you are running a 64 bit Windows 8 system, with a 32 bit version of Python 3.4.
you downloaded the 32 bit version of Pygame for Python 3.2 you need the one for the Python 3.4 version.
This one from official bitbucket should work as it is the correct version for python 3.4 32 bit compatibility.
https://bitbucket.org/pygame/pygame/downloads/pygame-1.9.2a0-hg_5974ff8dae3c+.win32-py3.4.msi
In my Anaconda 2.2 64bit with Python 3.4.3 the following line works well:
import shapely
But the following line:
from shapely.geometry.polygon import Polygon
returns the following error:
OSError: [WinError 126] The specified module could not be found
What am I missing?
EDIT
I tried with iNotebook, idle.exe and Eclipse. They all use Anaconda (the only Python installation on my computer) and they all show the same error.
If I type from shapely.geometry import Polygon in Eclipse, then I click on Polygon, then I press F3, Eclipse is able to open the module C:\Anaconda3\Lib\site-packages\shapely\geometry\polygon.py. So Eclipse is able to find it, but the execution fails.
EDIT 2
I just tried the same import on another computer with similar configuration and it works. The "only" difference between the two computers is that one has Windows 7 (it works) and one has Windows 8 (it doesn't).
I installed Anaconda and a few packages in both the computers following the same old checklist. The computer with Windows 8 can see the package from Eclipse, but can't import it.
I had a similar problem and it was due to the way that I improperly installed shapely (although this was on a Windows 7 machine, not Windows 8). For the initial install under which I couldn't import the geometry sub-module I installed shapely with the command:
pip install shapely
However after reading the documentation here more closely I saw that for Windows an executable installer needed to be used. That installer is a wheel file that needs to be launched by pip as well. So I uninstalled the first version of shapely with:
pip uninstall shapely
Then I launched the installer via the wheel file like this:
pip install your/file/path/Shapely‑1.5.9‑cp27‑none‑win32.whl
Note that you must download the wheel that matches the specs of the version of python that your applying the package to. I have 32-bit (win32) python 2.7 (p27) so the package above was the correct one. Note that the reference to 32 or 64 bit in the file name refers to the version of python, not to the version of windows.
Try with below one, it solved the issue for me (Windows 10):
conda install -c conda-forge shapely
shapely package docs
Try this:
from shapely.geometry import Polygon
That's how the docs list it:
http://toblerity.org/shapely/manual.html#polygons
Don't use anything but Python version 3.7. Download it now!
Then go to PyCharm (that's what I'm using) and open it, then download the file for your specific version (from here https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely) mine is Shapely-1.6.4.post1-cp37-cp37m-win_amd64.whl (this is respectively version 3.7 (37) and Windows (64) as seen above)
Now with your newly downloaded file, copy and paste it into where you are working from in PyCharm's folder location. For me this is: C:\Users\lewis\PycharmProjects\Project1\NewProject
Then you should see the newly copied file in PyCharm itself as well as where you put it.
Now right click the file in PyCharm Shapely-1.6.4.post1-cp37-cp37m-win_amd64.whl
and click OPEN IN TERMINAL then type:
pip install Shapely-1.6.4.post1-cp37-cp37m-win_amd64.whl
It should say "successful".
Then go into your working area and type:
from shapely.geometry import point
Run it. It should now work for all!
Be in mind that this will ONLY allow for the importing of Shapely in this one environment. So you'll have to copy the Shapely file into new folder locations if you use in other places.
Specs:
Be in mind I am working with a Windows 10, Python interpreter version 37, PyCharm, Virutalenv environment type. Also, make sure in the settings you are indeed in the Python 37 interpreter and not in a conda environment.
I am trying to learn the basics of game programming and I have installed pygame and pyopengl for that.
MyCode:
import sys
import OpenGL
from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.GLUT import *
def draw():
glClear(GL_COLOR_BUFFER_BIT)
glutWireTeapot(0.5)
glFlush()
glutInit(sys.argv)
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB)
glutInitWindowSize(250, 250)
glutInitWindowPosition(100, 100)
glutCreateWindow("Python OGL Program")
glutDisplayFunc(draw)
glutMainLoop()
draw()
When I run the above code in my command prompt using
python test.py
I get the following error.
Traceback (most recent call last):
File "test.py", line 13, in <module>
glutInit(sys.argv)
File "C:\Python27\lib\site-packages\pyopengl-3.0.2a5-py2.7.egg\OpenGL\GLUT\special.py", line 324, in glutInit
_base_glutInit( ctypes.byref(count), holder )
TypeError: 'NoneType' object is not callable
I don't understand why I am getting this error. Am I calling glutinit in a wrong way?
I am using Python 2.7.2.
I was using Python 2.7.3 on Windows 7 64-bit and had a problem causing the same symptoms as Noob.
But the above PyOpenGL reinstallation solution did not help me.
I try a longshot - installation of freeglut - and it helped!
I used Windows MSVC 2.8.0 binary package from here and dropped both 32-bit and 64-bit DLLs to my 32-bit (c:\Windows\SysWOW64) and 64-bit (C:\Windows\System32) dirs accordingly.
I installed PyOpenGL-3.0.2b2 on Python 3.2 using the setup.py install (with administrator privileges), it came out with the same error as the OP.
The setup script didn't copy the DLLS folder, so you have to copy it yourself
the whole folder \PyOpenGL-3.0.2b2\OpenGL\DLLS.
This worked for me, hope it helps anyone else.
in linux os you should install freeglut3
in ubuntu 12.04 :
sudo apt-get install freeglut3
It appears one has to download either glut or freeglut along with pyOpenGL. And most importantly, on my 64-bit Win7 system it only worked once I placed the glut32.dll file in C:\Windows\System (NOT C:\Windows\System32 - placing it in \System32 did not work!)
Here's a link for glut: http://user.xmission.com/~nate/glut.html
And freeglut: http://www.transmissionzero.co.uk/software/freeglut-devel/
Same exact problem was happening with me. I am using Python 2.7 on windows xp 32-bits.
Solution:
Just download glut-3.7.6-bin.zip from http://user.xmission.com/~nate/glut.html, unzip, place glut32.dll in C:\windows\system32 and you should be OK.
glutInit() expects 2 arguments, first an int as the number of command line arguments, then a list (of arguments).
glutInit(len(sys.argv),sys.argv) should do as there's no argc in module sys.
The problem was with my PyOpenGL installation. Earlier I installed it using easy_install.
So, as #Ferdinand suggested that there seems to be something wrong with your pyopengl installation.
I did a clean install using python setup.py install and it worked.
I had similar problem with python 2.7 64 bit windows.
Install the pyOpenGL package from http://www.lfd.uci.edu/~gohlke/pythonlibs/ . Many thanks to Christopher Gohlke for maintaining this !!
This appears to be a bug in the PyOpenGL win32 installer. It is supposed to copy over the DLLS directory from the source package (.zip) but fails to do so in my tests. This should be addressed in PyOpenGL itself, and I will do so for the next beta.
In the meantime, you can copy the OpenGL/DLLS directory from the PyOpenGL 3.1.0b2 source .zip into your site-packages/OpenGL directory to install GLUT and GLE DLLs without needing to install them into your system directories.
I just use python2.7.3 on windows-64bits and I met the problem.
I solved it by using an unoffical pyopengl package.
From the artical, it seems offical package doesn't support 64bits-windows.

I have just installed OpenCV on my Windows 7 machine. As a result, I get a new directory:
C:\OpenCV2.2\Python2.7\Lib\site-packages
In this directory, I have two files: cv.lib and cv.pyd.
Then I try to use the opencv from Python. I do the following:
import sys
sys.path.append('C:\OpenCV2.2\Python2.7\Lib\site-packages')
import cv
As a result I get the following error message:
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified module could not be found.
What am I doing wrong?
ADDED
As it was recommended here, I have copied content of C:\OpenCV2.0\Python2.6\Lib\site-packages to the C:\Python26\Lib\site-packages. It did not help.
ADDED 2
My environment variables have the following values:
Path=C:\Program Files\MiKTex\miktex\bin;C:\OpenCV2.2\bin;C:\Python26;
PYTHONPATH=C:\OpenCV2.2\Python2.7\Lib\site-packages
Do I need to change something? Do I need to add something?
ADDED 3
I think my question is general: How to use a library? Probably I need to find a *.ddl file somewhere? Then I need to use the name of the directory containing this file as a value to some environment variables? Or maybe I need to use sys.addpath? I also need to know how the way to call the library is related to the name of the file that contains the library.
ADDED 4
It is interesting that when I type import cv, I get:
ImportError: DLL load failed: The specified module could not be found.
But when I type import opencv I get:
ImportError: No module named opencv
ADDED 5
It has been suggested that I usthe e inconsistent version of python. In more details, OpenCV tries to use Python2.7 and I had Python2.6. So, I have installed Python 2.7. It makes difference. Now I do not have the old error message, but I have a new one:
ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import
ADDED 6
I have managed to resolve the problem by installing numpy. It took some time because I did not realized that there are different numpy installer corresponding to different versions of Python. Some details can be found in my answer to my own question (see bellow).
The problem was resolved. The following steps has been done:
A new version of python (version 2.7) has been installed.
After that I still was unable to run OpenCV because I had some problems with the numpy library.
I tired to install numpy but the installer did not see my new version of the Python.
I deleted the old version of Python as well as links to the old version in the Path system vatriable.
After that numpy installer was not able to finish the installation.
I have realized that I need to run another numpy installer that is associated with the Python 2.7. It can be found here.
Finally everything worked. I was able to "import cv".
I suspect you have the same problem I've run into. If you have a 64-bit version of Python, it cannot load 32-bit DLLs. OpenCV currently only ships 32-bit binaries. If you want 64-bit .pyd and .dll files, you have to compile them yourself. There are some instructions on the OpenCV Wiki, but it's not for the faint of heart. Expect to have a substantial time investment.
The easiest solution is to:
Uninstall 64-bit Python
Install a 32-bit distribution.
The PythonXY distribution includes pyopencv -- a good set of OpenCV hooks. The only limitation is that it's 32-bit, so don't make plans to process gigapixel astronomy data with it! ;)
If you must have the 64-bit version, follow these instructions to get it OpenCV to compile with Visual Studio 2010. There's a discussion on stackoverflow that describes building 64-bit apps with VC Express.
EDIT: OpenCV now ships with 64-bit Python binaries. The .dll files need to go somewhere in your path (I put them in the scripts folder), and the .pyd files go in your site-packages directory.
I had trouble interfacing OpenCV with Python, and I was looking all over the place for help. Here's what worked for me. I basically followed this post: http://opencvpython.blogspot.com/2012/05/install-opencv-in-windows-for-python.html. After downloading and extracting OpenCV 2.4.6, you basically get a folder called "opencv" with a bunch of stuff in it. Navigate to build->python->2.7. Inside, there is only one file called "cv2.pyd". I copied this file and pasted it in "python-2.7.5\Lib\site-packages". I'm actually using the Spyder IDE, and it works fine. In the python interpreter, typing in "import cv" worked for me.
Maybe you should edit your environment variable
right click on the "My Computer" or something like this, click on properties.
In the properties window click on the Advanced tab.
Then, the environment variables button.
Change the path.
