No module named ‘cv2.cv2’

I am a beginner at computers. I use Anaconda python 3.6 in windows 10. I have already installed OpenCV using this command:

But when I try to import cv2 using this:

this error shows up:

How can I install openCV for python?

6 Answers 6

Step 1: Uninstall the opencv first if you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g. cv2 module in the root of Python’s site-packages)):

Step 2: Install the package afresh

Hope that works!

Create Virtual Environment

Activate the environment

Install OpenCV and other important packages

Test your installation

In my case, using Python 3.8 on Windows 10 and Pycharm (or VS Code as well), I have this same issue.

Finally I noticed that the Antivirus (Nod32) deletes the cv2.cp38-win32.pyd file that should be in the cv2 folder. I simply paused the protection, installed opencv with pip install opencv-python command and it worked just fine.

I hope it helps someone.

I had this exact same problem on Windows 10. Uninstalling via pip and then reinstalling in my virtual environment fixed everything up for me.

Try reinstalling openCV — it worked for me.

To uninstall:

To reinstall:

I used the answer provided here and it worked.

By running pip install opencv_python-3.4.5-cp36-cp36m-win_amd64.whl

Bug/Issue Description:
G:\PySceneDetect-0.5>scenedetect -i «G:\I2\I.mp4» detect-content list-scenes split-video —copy
Traceback (most recent call last):

Computing Environment:

• OS: Windows 10 Pro
• Python Version: 3.7.0 32bit
• OpenCV Version: Don’t know, don’t install this.

Additional Information:
I downloaded source code zip file, after extracting I run setup file. I don’t install opencv cause I don’t have any issue with previous issue as I did same way.

You need to install the opencv-python module via:

Also note you can install PySceneDetect the same way via:

If the above methods fail, you can also download the cv2 module from:

For 32-bit Python 3.7, you want the file opencv_python‑3.4.3‑cp37‑cp37m‑win32.whl, and install it via pip (e.g. pip install [file] ). Also note that you can install PySceneDetect via pip now (e.g. pip install scenedetect ).

I’ll try to have a more descriptive error message in the program in the next release, thanks for bringing this up. Let me know if you have any issues getting OpenCV installed.

Edit: I didn’t add OpenCV as a dependency to the setup.py file because the opencv-python package used to not include static libraries, but it seems to now. The next release of PySceneDetect (v0.6) will include this fix, so it installs cleanly when you run:

raj6996 commented Sep 2, 2018

After installing with «pip install opencv-python» command, I got this:

Error: Invalid value for split-video: mkvmerge is required for split-video -c/—copy.
Install the above tool to enable video splitting support.

Then I recalled you told to use MKVmerge.exe on scenedetect folder, so I used portable and copy MKVmerge.exe and it works flawlessly.
by the way, how to use ffmpeg with scenedetect. kindly reply me step by step for being total noob on programing field. thanks.

Breakthrough commented Sep 2, 2018 •

Likewise, you do the same thing (just drop ffmpeg.exe where scenedetect.exe is). I’ll try to make the download link a little bit more apparent, and when I finalize the Windows release (portable/installer), it should include both programs for you as well.

If you have 32-bit Windows, you can find download links for ffmpeg/mkvmerge from:
https://pyscenedetect.readthedocs.io/en/latest/examples/video-splitting/

Let me know if this solves it, thanks again for your help in testing the software!!

You need to pip install opencv-python as above again.

Python — ModuleNotFoundError: No module named

I’m new in Python and I’m having the following error with this simple example:

This is my project structure:

And this is the error when I execute the src/main.py file:

If I move the main.py file to the root and then I execute this file again, works. but is not working inside src/ directory

This is my main.py :

Note: When I execute the same code from Pycharm is working fine, but not from my terminal.

Your PYTHONPATH is set to the current directory from the program you execute. So if you’re executing something inside a directory src , it will never be able to find the directory lib because it’s outside the path. There’s a few choices;

• Just move lib/ into src/ if it belongs to your code. If it’s an external package, it should be pip installed as Henrique Branco mentioned.
• Have a top-level script outside of src/ that imports and runs src.main . This will add the top-level directory to python path.
• In src/main.py modify sys.path to include the top-level directory. This is usually frowned upon.
• Invoke src/main.py as a module with python -m src.main which will add the top-level directory to the python path. Kind of annoying to type, plus you’ll need to change all your imports.

If I may add to MarkM’s answer, if you wanted to keep your current directory structure and still make it work, you could add a setup.py in your root dir, where you can use setuptools to create a package you could install.

If your file had something along the lines of:

And then you do pip install [—user] -e path/to/directory you’ll get an «editable package» which will effectively a symlink to the package in your development directory, so any changes you make will not require a reinstall (unless of course you rejig package structure or add/remove/edit entry points).

This does assume your src/main.py has a main function.

You’ll also need __init__.py files in your «package» directories, even in Python3, as otherwise Python assumes these are namespace packages (Won’t go into detail) and the find_packages() call won’t find them.

This will also allow your relative imports to work. Absolute imports will only work when invoking the script from your entry point but not when calling the script directly in your development directory.
