How to Install OpenCV in Python

Tutorial

While OpenCV is imported with the import cv2 line of code, the official OpenCV Python package is called opencv-python .

To install the Python OpenCV package, run:


pip install opencv-python

Next Steps

OpenCV can be used with the open source supervision Python package.

supervision provides an extensive range of functionalities for working with computer vision models. With supervision, you can:

1. Process and filter detections and segmentation masks from a range of popular models (YOLOv5, Ultralytics YOLOv8, MMDetection, and more).
2. Process and filter classifications.
3. Compute confusion matrices.

And more! To learn about the full range of functionality in supervision, check out the supervision documentation.
