As you can see I have imported the modules correctly using pip install. I googled a bit why the module was not imported and I realized I have to add it to PATH. I did that too but now there is a new error something about a syntax error
File "pygame/__init__.py",
self.reason = f"{exc_type.__name__}: {self.info}"
Is this because my chrome book can not run Pygame or is the problem something else?
Picture of my terminal with the error:
you need to run python3. to start python 3. Just running python starts python 2.7.
you have your installed packages in python 3.9 version while your python environment is 2.7, look for python3 executable and try with that version
I'm trying to run a python script that uses a custom module written by someone else. I created that module by running CMake according to the creator's instructions. Running my python script, I get the error: ImportError: libopencv_imgproc.so.3.1: cannot open shared object file: No such file or directory. This error is caused by the module I created earlier.
There is no file of that name since I have OpenCV 3.2.0 installed, so in usr/local/lib there's libopencv_imgproc.so.3.2.0. I don't know how to fix this or where to start looking. The CMakeLists.txt of the module has a line
find_package(OpenCV 3 COMPONENTS core highgui imgproc REQUIRED).
I tried changing it to
find_package(OpenCV 3.2.0 COMPONENTS core highgui imgproc REQUIRED),
without success.
The problem was an old version of the module lurking an a different folder where the python script was actually looking. This must have been created in the past with an OpenCV 3.1 environment.
My current version of Python is the newest 3.5 and the only available PyGame was for 3.2 (both PyGame and Python are 32-bit). I've scoured stackoverflow for a resolution and can't find any way to make this work. I've installed the PyGame easy installer and placed it in the directory where my Python install is, and in Visual Studio (I've also tried this in PyCharm as well as the standard Python IDE in command prompt), upon typing
import pygame or import sys, pygame
I'm presented with the error Import Error was
unhandled by user code - DLL load failed: The specified module could not be found.
My final solution is to uninstall Python 3.5 and install the version which matches PyGame.
This shouldn't have anything to do with Python version. You are missing a dynamic library (the DLL). This means that either the DLL is not on your system or Python can't find it. You should probably try the msi/exe installer for PyGame mentioned here, as it should install any dependencies. This would fix the issue if it is caused by the DLL being absent from your system.
It could also be caused by the libraries not being on PYTHONPATH. Search the error you received and you should see quite a few answers on fixing this.
If you're just getting started, you may want to look at a different library. There are likely quite a few game libraries for Python that can be installed with a simple pip install. You could then return to PyGame when you are more comfortable if you wanted.
get it from here: https://www.dropbox.com/s/hnmcaq1rf6zn7m3/pygame-1.9.2a0-cp34-none-win32.whl?dl=0
download it and install it by putting it in C:\python3.5\Scripts
then run pip3 install pygame-1.9.2a0-cp34-none-win32.whl
(this is for 3.4, but 3.5 works too)
it should work, and your error has nothing to do with the package, it's just that you do not have a DLL file, install it again from the website above
I have a situation very much like the one at Error "ImportError: DLL load failed: %1 is not a valid Win32 application", but the answer there isn't working for me.
My Python code says:
import cv2
But that line throws the error shown in the title of this question.
I have OpenCV installed in C:\lib\opencv on this 64-bit machine. I'm using 64-bit Python.
My PYTHONPATH variable: PYTHONPATH=C:\lib\opencv\build\python\2.7. This folder contains cv2.pyd and that's all.
My PATH variable: Path=%OPENCV_DIR%\bin;... This folder contains 39 DLL files such as opencv_core246d.dll.
OPENCV_DIR has this value: OPENCV_DIR=C:\lib\opencv\build\x64\vc11.
The solution at Error "ImportError: DLL load failed: %1 is not a valid Win32 application" says to add "the new opencv binaries path (C:\opencv\build\bin\Release) to the Windows PATH environment variable". But as shown above, I already have the OpenCV binaries folder (C:\lib\opencv\build\x64\vc11\bin) in my PATH. And my OpenCV installation doesn't have any Release folders (except for an empty one under build/java).
What's going wrong? Can I tell Python to verbosely trace the loading process? Exactly what DLL files is it looking for?
I noticed that, according to http://www.dependencywalker.com/, the cv2.pyd in C:\lib\opencv\build\python\2.7 is 32-bit, whereas the machine and the Python I'm running are 64-bit. Could that be the problem? And if so, where can I find a 64-bit version of cv2.pyd?
Unofficial Windows Binaries for Python Extension Packages
You can find any Python libraries from here.
Please check if the Python version you are using is also 64 bit. If not then that could be the issue. You would be using a 32-bit Python version and would have installed a 64 bit binaries for the OpenCV library.
Wow, I found yet another case for this problem. None of the above worked. Eventually I used python's ability to introspect what was being loaded. For Python 2.7, this means:
import imp
imp.find_module("cv2")
This turned up a completely unexpected "cv2.pyd" file in an Anaconda DLL directory that wasn't touched by multiple uninstall/install attempts. Python was looking there first and not finding my good installation. I deleted that cv2.pyd file and tried imp.find_module("cv2") again and python immediately found the right file and cv2 started working.
So if none of the other solutions work for you, make sure you use Python introspection to see what file Python is trying to load.
In my case, I have 64-bit Python, and it was lxml that was the wrong version--I should have been using the x64 version of that as well. I solved this by downloading the 64-bit version of lxml here:
https://pypi.python.org/pypi/lxml/3.4.1
lxml-3.4.1.win-amd64-py2.7.exe
This was the simplest answer to a frustrating issue.
I just had this problem. It turns out it was just because I was using an 64-bit version of the OpenCV file. I tried the x86 and it worked.
I had the same problem. Here's what I did:
I downloaded the pywin32 wheel file from here, then
I uninstalled the pywin32 module. To uninstall, execute the following command in a command prompt.
pip uninstall pywin32
Then, I reinstalled pywin32. To install it, open the command prompt in the same directory where the pywin32 wheel file lies. Then execute the following command.
pip install <Name of the wheel file with extension>
Wheel file will be like: piwin32-XXX-cpXX-none-win32.whl
It solves the problem for me.
I copied cv2.pyd file from /opencv/build/python/2.7/x86 folder instead of from /x64 folder to C:/Python27/Lib/site-packeges. I followed rest of the instructions provided here.
Added by someone else, not verified: I also copy file cv2.pyd to folder C:/Python27/Lib/site-packages/cv2. It works.
For me the problem was that I was using different versions of Python in the same Eclipse project. My setup was not consistent with the Project Properties and the Run Configuration Python versions.
In menu Project → Properties → PyDev, I had the Interpreter set to Python 2.7.11.
In Run Configurations → Interpreter, I was using the Default Interpreter. Changing it to Python 2.7.11 fixed the problem.
If your build system (CMake in my case) copies the file from <name>.dll to <name>.pyd, you will get this error if the original file wasn't actually a DLL file. In my case, building shared libraries got switched off, so the underlying file was actually a *.lib.
I discovered this error by loading the pyd file in Dependency Walker and finding that it wasn't valid.
Update NumPy.
pip install numpy --upgrade
It works for me!
This one worked for me:
pip install -- pywin32==227
I faced the same issue when I uninstalled and reinstalled a different version of 2.7.x of Python on my system using a 32-bit Windows Installer. I got the same error on most of my import statements.
I uninstalled the newly installed Python, downloaded a 64-bit Windows installer, reinstalled Python again, and it worked.
So I had problems installing vtk under Windows (as I use Python 3.7, there isn't any binary available so far. Just for older Python versions pip install vtk is not working)
I did wrote Python in my cmd:
Python 3.7.3 on win32
So I now know I have Python 3.7.3 running on a 32 bit.
I then downloaded the correct wheel at VTK‑8.2.0‑cp37‑cp37m‑win32.whl
Next I installed that wheel:
pip install VTK-8.2.0-cp37-cp37m-win32.whl
Then I tested it and it worked:
python
import vtk
I experienced the same problem while trying to write code concerning speech-to-text.
The solution was very simple. Uninstall the previous pywin32 using the pip method:
pip uninstall pywin32
The above will remove the existing one which is by default for 32 bit computers. And install it again using
pip install pywin32
This will install the one for the 64 bit computer which you are using.
I had a similar issue while trying to run uvicorn,
Creating a new virtual environment and reinstalling the python packages worked
You can install opencv from official or unofficial sites.
Refer to this question and this issue if you are using Anaconda.
It has a very simple solution.
After installing opencv
place
cv2.pyd from C:\opencv\build\python\2.7\ **x64** to C:\Python27\Lib\site-packages
instead of, place cv2.pyd from C:\opencv\build\python\2.7\ **x86** to C:\Python27\Lib\site-packages
I got this error when trying to import MySQLdb.
What worked for me was to uninstall Python and then reinstall it.
I got the error after installing npm (https://www.npmjs.com/get-npm). One thing it did was install Python even though I already had it.
First I copied cv2.pyd from /opencv/build/python/2.7/x86 to C:/Python27/Lib/site-packeges. The error was
"RuntimeError: module compiled against API version 9 but this version of numpy is 7"
Then I installed numpy-1.8.0-win32-superpack-python2.7.exe and OpenCV works fine.
>>> import cv2
>>> print cv2.__version__
2.4.13
Please make sure that you have installed a Python 2.7.12 or below version. Otherwise you will definitely get this error.
Make sure the Oracle client is 64 bit installed if the OS is 64 bit.
Make sure the Microsoft Visual C++ compiler for Python 2.7 is 64 for bit for a 64 bit OS or 32 bit for 32 bit.
Note: If your OS is 64 bit, install all packages of 64 bit or if the OS is 32 bit, install the 32-bit package.
This has worked for me. I have tried different methods, but this was my best solution.
Open a command prompt and type the following;
pip install opencv-python
(Make sure your Internet connection is on.)
After that, try importing it again.
It could also be that your Anaconda version is 32 bit when it should be 64 bit.
If you are using pycharm I go to settings -> python interpretation and click the + button and search for the name on the list of python packages there

I found the solution. Maybe you can try to use the cmd window rather than the Anaconda prompt window to start your first Scrapy test.
My server has python older version(2.6~), so I have created a separate dir for installing latest python. I have installed from binary .
Now, got error that 'bz2 module is not available'
got this problem when installing django-celery.
it is actually working from system level python like this:
/usr/bin/python:
python shell opens......
then, import bz2; works !!!
python (means, locally installed python, after source /venv/bin/activate)
in python shell, import bz2; says that it is not available. Can you please make it work for my local version( not global one).
Resources I found and tried from :
ImportError: No module named bz2 for Python 2.7.2
Python's bz2 module not compiled by default
A very similar question describes the same problem but for zlib. In short, you'll need libbz2.so and its headers in some location where Python can find them. You might need to download the bzip2 source code and compile/install that in your homedir as well.
