TLDR

Fast and easy, that's how we roll! Install OpenCV with Conda using the magic spell:

conda install -c conda-forge opencv

The wonderful world of conda-forge ensures you receive a polished and up-to-date OpenCV version for your Conda environment.

Pre-install: Compatibility is key

Like pancakes and maple syrup, OpenCV and your environment need to be compatible. Use the following command to make sure of that:

conda search opencv

Doing so is like asking "Hey Conda, got some OpenCV for my environment here?". If Conda nods, you're good to go.

When there's an issue: Alternate channels

On gray days when conda-forge doesn't serve, try other channels like menpo:

# Because new friends might be different, better, weirder conda install -c menpo opencv

And before you question, yes, add the channel to Conda's list like this:

# Hey Conda, meet menpo conda config --add channels menpo

Remember, Anaconda by default keeps an eye on the weather, stay updated for smooth sailing! 🌩🦆

Plan C: Manual installation

When all else fails, manually download OpenCV from its official site, remember old-school mail? Pretty similar, deliver cv2.pyd directly to Anaconda's site-packages directory. But bother Conda only as the last resort. 🏪📫

Getting your hands dirty (Tips & Troubleshooting)

Environment setup: Create your own world

When you have too many toys and want a fresh playground, create a new Conda environment:

# Because a new playground is everyone's childhood dream conda create --name opencv-env

Remember to activate it with conda activate opencv-env before setting up base (Installing OpenCV).

Installation success: Seeing is believing

To make sure your new toy OpenCV was delivered without errors, ask Python:

import cv2 print(cv2.__version__)

If Python's happy, you're on track for a fun ride! 🚂

IDE setup: Housekeeping rules

For folks using an IDE, like Spyder, ensure IDE finds Conda's house and the packages installed inside. Oh, be extra careful when inviting other guests like FFMPEG for OpenCV powered video processing.
