I recently deleted the default python version on Fedora 31 and installed python 3.9 then made it as default, now I have multiple versions of python.
If I type: whereis python in my terminal this list appear:
python: /usr/bin/python /usr/bin/python3.9 /usr/bin/python3.7 /usr/bin/python3.9-config /usr/bin/python3.7m /usr/bin/python3.9-x86_64-config /usr/lib/python3.9 /usr/lib/python2.6 /usr/lib/python3.7 /usr/lib64/python3.9 /usr/lib64/python3.7 /usr/local/bin/python3.7m-config /usr/local/bin/python3.7 /usr/local/bin/python3.7m /usr/local/lib/python3.7 /usr/include/python3.9 /usr/include/python3.7m /usr/share/man/man1/python.1.gz /usr/src/Python-3.7.4/python
If I type pip then I get ModuleNotFoundError: No module named 'pip'
Also multiple packages are broken such as dnf, argcomplete, pip, etc.
I cannot update or install anything.
How can I solve this problem ?
Grab/Download the original python RPMs for your distro and reinstall them that way if they're not still cached under /var ....
With Python 3.9 you should use pip3...So install python3-pip.
That should do the trick
I tried many solutions and didn't work, however I ended up backing up my data and completely deleting the OS, then I downloaded the last version of fedora and restored my data on it.
thanks for your time
I ran into this unfortunate situation as well on Fedora 35. dnf, yum, and a bunch of other things broke.
I didn't manage to get Python 3.10 back through dnf, yum, or apt-get. I downloaded the rpm from https://fedora.pkgs.org/35/fedora-x86_64/python3-3.10.0-1.fc35.x86_64.rpm.html. It did require a dependency of python3-libs which I downloaded from: https://fedora.pkgs.org/35/fedora-x86_64/python3-libs-3.10.0-1.fc35.x86_64.rpm.html.
I installed python3-libs first with sudo rpm -i python3-libs-3.10.0-1.fc35.x86_64.rpm --force as there were some file writing conflicts. I ran the same command for the python3.10 rpm with the --force flag as well since there were 2 conflicts. After that, everything worked perfectly! Managed to dodge having to do a full reinstall.
I have to install py4jdbc module in python on windows 10, but i am having the followings errors when i try to use pip install py4jdbc or from the source:
Error 1: "The executable sbt cannot be found"
Pip Error
Error 2: "the file doesn't exist..."
Error From source
I have sbt already install and in the path.
Is there something i am missing?
It seems py4jdbc was not tested on Windows as it uses a function distutils.spawn.find_executable that on w32 looks only for sbt.exe while you have sbt.bat.
My advice is to try to fix py4jdbc. Download it with pip download py4jdbc (it also downloads dependency py4j), unpack the archive py4jdbc-0.1.6.8.tar.gz and edit setup.py: at line 28 replace 'sbt' with 'sbt.bat'. Install with pip install . (<- the dot at the end means "the current directory".)
I am using Win7 64 bit machine with Python 2.7 installed. I have installed swigwin 3.0.5. When I do "pip install M2Crypto" I got the following errors:
SWIG\_m2crypto.i(30) : Error: Unable to find 'openssl\opensslv.h'
SWIG\_m2crypto.i(33) : Error: Unable to find 'openssl\safestack.h'
SWIG\_evp.i(12) : Error: Unable to find 'openssl\opensslconf.h'
SWIG\_ec.i(7) : Error: Unable to find 'openssl\opensslconf.h'
In some links I found the suggestion is to install openssl-dev. But I could not find the equivalent package for windows (pip install openssl-dev does not work and I have done pip install pyOpenSSL which did not help me).
Thanks in advance for your help in this issue.
Not sure what your OS is. But to solve the issue on MAC OS X Yosemite you need to reinitialise xcode command line tools by using this command in terminal.
xcode-select --install
This solved the problem for me.
I am running Anaconda Python 2.7 on a Win7 x64 machine and used
pip install PyOpenGL PyOpenGL_accelerate
at the Anaconda command line to install PyOpenGL.
I have some code (not my own I must confess) that makes use of glutInit
import sys
import math
import numpy
import OpenGL
from OpenGL.GL import *
from OpenGL.GLUT import *
import Image
import linkage
# ... a whole load of definitions etc ...
glutInit(sys.argv)
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB)
glutInitWindowSize(600, 600)
glutCreateWindow('linkage')
init()
initWindow()
glutIdleFunc(idle)
glutMainLoop()
I run by entering the following at the command line:
python main.py peaucellier.txt
But then get the following error (line 371 is the glutInt(sys.argv) line above)
File "C:/Users/Owner/Documents/Python Scripts/linkage/main.py", line 371, in <module>
glutInit(sys.argv)
File "C:\Anaconda\lib\site-packages\OpenGL\GLUT\special.py", line 333, in glutInit
_base_glutInit( ctypes.byref(count), holder )
File "C:\Anaconda\lib\site-packages\OpenGL\platform\baseplatform.py", line 407, in __call__
self.__name__, self.__name__,
NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling
I have looked at similar errors posted in this forum but none of the proposed fixes are working which is why I'm asking, what's wrong here?
Is the installation at fault? Are the imports correct?
EDIT: After trying many many fixes for the official release I am now using an unofficial release that works perfectly from Unofficial Windows Binaries for Python Extension Packages
According to the link below the problem was with the glut installation rather than pip install. It seems glut files are not part of PyOpenGL or PyOpenGL_accelerate package. You have to download them seperately.
https://stackoverflow.com/a/39181193/7030177
Windows user can use the link below to download glut as mentioned in the given link.
ftp://ftp.sgi.com/opengl/glut/glut3.html.old#windows
Linux Users can just install glut using the following command:
sudo apt-get install freeglut3-dev
Hope this helps :)
After looking around for a solution to a similar problem I ran across this google group that answers the question: https://groups.google.com/forum/#!topic/glumpy-users/aC1NjEHXtEE
There is a problem with OpenGL.GLUT when downloaded as pip from the official source. Uninstall OpenGL using pip, then download OpenGL from http://www.lfd.uci.edu/~gohlke/pythonlibs/
For people on Linux with this error after installing via easy_install PyOpenGL or pip install PyOpenGL.
-> Install the distribution package as: sudo apt-get install python-opengl - this works for me.
If installing PyOpenGL from easy_install, pip or conda, make sure that you have already installed a GLUT implementation, such as FreeGLUT (prebuilt Windows binaries).
For FreeGLUT, copy the distributed files to a location on your hard drive and then add the path to the bin directory (which contains the GLUT DLLs) to your PATH environment variable. Then PyOpenGL should work as expected.
It is mainly because you're running 64-bit windows put pip is installing 32-bit version of PyOpenGL.
To fix this, follow these steps:
Uninstall existing PyOpenGL, Run pip uninstall PyOpenGL PyOpenGL_accelerate
Download the 64-bit builds of PyOpenGL and PyOpenGL accelerate from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopengl
How to choose which one to download? Well, first you need to check your python version. Run python --version to determine.
Then according to your version download the whl files for PyOpenGL and PyOpenGL accelerate. For example, if you have Python 3.8, download these 2 files:
PyOpenGL‑3.1.5‑cp38‑cp38‑win_amd64.whl
PyOpenGL_accelerate‑3.1.5‑cp38‑cp38‑win_amd64.whl
Similarly, if you run Python 3.9, download these instead:
PyOpenGL‑3.1.5‑cp39‑cp39‑win_amd64.whl
PyOpenGL_accelerate‑3.1.5‑cp39‑cp39‑win_amd64.whl
Note: Must download amd64 ones, after all, you're running 64-bit windows.
Now go to the folder where you downloaded the files and run powershell/cmd with administrator there.
Use pip to force install those files. For example:
pip install PyOpenGL-3.1.5-cp38-cp38-win_amd64.whl --force-reinstall
pip install PyOpenGL_accelerate-3.1.5-cp38-cp38-win_amd64.whl --force-reinstall
Note: Install PyOpenGL first and then PyOpenGL_accelerate
If the installation succeeds, you may be able now to run.
Some facts to make sure:
*All platforms must be of the same bit version.
*System type, python, OpenGL needs to be of the same bit version. In my case it was x64 bit
*It is necessary to restart your desktop if you reinstall any one of them (Python, OpenGL)
*It is recommended to keep your pip version at 20.3, I downgraded it from 21.1.3
I got the same error and a solved installing required files from here.
Download these files:
PyOpenGL-3.1.1-cp27-cp27m-win32.whl (download if your computer 32 bits )
PyOpenGL-3.1.1-cp27-cp27m-win_amd64.whl (download if your computer 64 bits )
PyOpenGL_accelerate-3.1.1-cp27-cp27m-win32.whl (download if your computer 32 bits )
PyOpenGL_accelerate-3.1.1-cp27-cp27m-win_amd64.whl (download if your computer 64 bits )
install these .whl files for 64 bits:
pip install PyOpenGL-3.1.1-cp27-cp27m-win_amd64.whl
pip install PyOpenGL_accelerate-3.1.1-cp27-cp27m-win_amd64.whl
install these .whl files for 32 bits:
pip install PyOpenGL-3.1.1-cp27-cp27m-win32.whl
pip install PyOpenGL_accelerate-3.1.1-cp27-cp27m-win32.whl
for python 2.7, PyopenGL needs vc++ 9 compiler, download and install it.
then:
python -m pip install --upgrade pip
pip install image
pip install numpy
pip install PyOpenGL PyOpenGL_accelerate
I downloaded freeglut
unzipped it and added bin directory to the path
when calling: glutCreateWindow("sometitle")
changed to glutCreateWindow(b'sometitle')
and got it run on windows 7
My case is different, Python 3.6 and windows 10. However exactly same error message. Tried all above solutions, no success.
Downloaded WHL file right to my computer and version of python from HERE
Then pip installs filename.Whl, no more issue!
The answer was from a Chinese website: Answer Link
Yes, this happened to me on Windows 10 running python 2.713 anaconda 4 64 bit. I had used conda to install pyopengl but received the same error as above. So I downloaded freeglut from transmissionzero and just copied the freeglut.dll (64 bit for me) to the same directory as my source file (it just needs to be in the dll searchpath) and all was good.
I know it is a little late. I also encountered this problem with python 2.7 (32 bits) in windows. I tried the method mentioned by user2723240 but still failed. Finally, I solved this problem by copying glue32.dll to System32 in C drive and copy glue32.dll into my source file directory. It works well now.
On linux, the pyopengl module attempts to use ctypes module to load the glut library as simply 'glut'. According to ctypes documentation the loadLibrary routine must be given the complete filename. Therefore, I made a symbolic link to libglut.so and named it 'glut' and everything just worked.
The following command should work for Anaconda users:
conda install -c conda-forge freeglut
https://anaconda.org/conda-forge/freeglut
On windows, although PyOpenGL says it installs freeglut by default, it does not.
To patch it, you must download or compile freeglut (other answers here contain the appropriate links) and place it in a new site-packages/OpenGL/DLLS folder inside to your existing OpenGL site-packages installation.
Once there, the freeglut.dll needs to have the bits and the MSVC version appended to the filename. OpenGL/platform/win32.py has the details on exactly how it's detected.
To make it clearer the filename needs to be the one printed from the following script:
import sys
import platform
if sys.hexversion < 0x2070000:
vc = 'vc7'
elif sys.hexversion >= 0x3050000:
vc = 'vc14'
elif sys.hexversion >= 0x3030000:
vc = 'vc10'
else:
vc = 'vc9'
size = platform.architecture()[0].strip('bits')
print(f'freeglut{size}.{vc}.dll')
Step 1
Install python in your system windows 10/11 preferred. for python 3.8.0 : https://www.python.org/ftp/python/3.8.0/python-3.8.0-amd64.exe
If you have already installed then check for your python version
Open terminal and type "python --version"
it will display your python version. for example I have installed python 3.8.0.
Step 2
Next open terminal and run the below command
python -m pip install --upgrade pip==20.3
sometimes you have higher version of pip installed but its okay to downgrade back to version 20.3
Step 3
now for installing OpenGL go to this site : https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopengl
and download
PyOpenGL‑3.1.6‑cp38‑cp38‑win_amd64.whl (for 64bit windows) or
PyOpenGL‑3.1.6‑cp38‑cp38‑win32.whl (for 32 bit)
and
PyOpenGL_accelerate‑3.1.6‑cp38‑cp38‑win_amd64.whl (for windows 64bit) or
PyOpenGL_accelerate‑3.1.6‑cp38‑cp38‑win32.whl (for windows 32bit)
Note : I have in installed python 3.8.0. so I downloaded PyOpenGL having cp38 word in it. If you have installed python 3.9 or other version download the above mentioned file having name cp39,cp10 etc.
after downloading both files according to your python version. put it a folder.
Step 4
then open terminal from that folder. Windows 10 lets you launch Command Prompt in a folder through the File Explorer's address bar. Type “cmd” in the address bar and then hit Enter
after opening terminal enter the below command
pip install PyOpenGL-3.1.6-cp38-cp38-win_amd64.whl --force-reinstall
then after installing it run the below command
pip install PyOpenGL_accelerate-3.1.6-cp38-cp38-win_amd64.whl --force-reinstall
Note : Don't forget to change the file name ( e.g. : PyOpenGL-3.1.6-cp38-cp38-win_amd64.whl) to the file name that you have downloaded.
I tried installing pyzmq by http://ipython.org/ipython-doc/dev/install/install.html as I want to install ipython. But it has dependency on pyzmq which has dependency on gcc. I already have gcc installed but still I am getting the following error while install pyzmq.
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1
The script also has following in it:
If you expected pyzmq to link against an installed libzmq, please check to make sure:
* You have a C compiler installed
* A development version of Python is installed (including headers)
* A development version of ZMQ >= 2.1.4 is installed (including headers)
* If ZMQ is not in a default location, supply the argument --zmq=<path>
* If you did recently install ZMQ to a default location,
try rebuilding the ld cache with `sudo ldconfig`
or specify zmq's location with `--zmq=/usr/local`
You can skip all this detection/waiting nonsense if you know
you want pyzmq to bundle libzmq as an extension by passing:
`--zmq=bundled`
I will now try to build libzmq as a Python extension
I already have all the above but still issues. I am guessing I have path issues i.e. may be pyzmq is looking at other location but how do I solve this problem
This is a huge issue in Windows to install ipython. I would recommend Windows users to never go the pip or easy_install way to install it. I faced a lot of issues like above. I read that it still has dependencies issues on github i.e. via pip.
I got it installed finally by this:
Download and install Anaconda
Update IPython to the current version by:
Go to Anaconda directory or look for anaconda cmd & do the following:
conda update conda
conda update ipython
