I guess this is relevant: https://github.com/aleju/imgaug/issues/473
Thanks~ Could you please provide the steps for reproducing the conflicts? We would like to check and fix.
This is clearly stated on OpenCV's PyPI page:
There are four different packages (see options 1, 2, 3 and 4 below) and you should SELECT ONLY ONE OF THEM. Do not install multiple different packages in the same environment. There is no plugin architecture: all the packages use the same namespace (cv2). If you installed multiple different packages in the same environment, uninstall them all with pip uninstall and reinstall only one package. a. Packages for standard desktop environments (Windows, macOS, almost any GNU/Linux distribution) Option 1 - Main modules package: pip install opencv-python Option 2 - Full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python (check contrib/extra modules listing from OpenCV documentation)
I don't believe there should be any need to install both and as mentioned, it causes issues.
We're currently seeing: AttributeError: module 'cv2.ximgproc' has no attribute 'niBlackThreshold'
. Going to try to change versions to fix for now.

You're absolutely right! Having both
opencv-python
andopencv-contrib-python
listed in therequirements.txt
of the PaddleOCR GitHub repository can indeed lead to conflicts. Here's why:opencv-contrib-python
is essentially an extension ofopencv-python
, containing additional modules and algorithms. Installing both packages installs many of the same files, potentially causing version clashes and unexpected behavior.opencv-python
andopencv-contrib-python
differ, pip might not be able to resolve the conflict, leading to installation errors or missing functionalities.opencv-python
oropencv-contrib-python
. Having both listed could lead to unexpected dependency conflicts for those libraries.Solutions:
There are a couple of ways to address this redundancy and potential conflict:
opencv-contrib-python
only: Since it includes all functionalities ofopencv-python
, using onlyopencv-contrib-python
is sufficient. This simplifies the dependency list and avoids potential conflicts.requirements.txt
using version specifiers (e.g.,opencv-python==4.5.5
,opencv-contrib-python==4.5.5
).opencv-python
andopencv-contrib-python
.It's generally recommended to avoid having both packages listed unless absolutely necessary. Choosing the appropriate approach depends on your specific requirements and the functionalities you need in your project.
I hope this explanation clarifies the potential conflict and provides helpful solutions!
