In summary, the conversation discusses the installation of OpenCV, a library for image processing, using the Python Anaconda distribution. The necessary command to install OpenCV is "conda install -c conda-forge opencv". The "-c" option specifies the channel for loading the library from, in this case, conda-forge. The purpose of this option is to specify where to load the library from. The keyword "forge" refers to a channel where the library is uploaded.

TL;DR Summary
Installing OpenCV, python
Hello Everyone,

I am trying to install OpenCV, which is a library for image processing. I am downloading the Python Anaconda distribution where to use OpenCV. I read that the following commands are needed at the prompt:

conda install -c conda-forge opencv

install means install the library. conda is the installation manager for Anaconda (when using regular Python, i.e. without downloading any distributions, we can install libraries without any extra command like conda, correct?)

What about the -c part? What does it mean?

And what does the keyword forge mean and do in the context of uploading the library?

Thank you!
