@berak: It appears that in this case, your comments about Anaconda were warranted. I resisted unloading it, since Anac

Thanks for getting back, Supra. Tensorflow 2.0 GPU version was already installed (via Anaconda). That doesn't seem to

Uh-oh... I was hoping that was not the case. It has been permanently removed from my cmake-gui menus. I've tried builds

Awesome that you knew this. I have no idea how you found enough info to make that connection, but it makes sense. I tru

@berak: Did you ever figure out what caused the BUILD_opencv_python3 option to reappear? It never came back for me.

Fast math flags: ENABLE_FAST_MATH, and CUDA_FAST_MATH I've seen examples of cmake files that set flags ENABLE_FAST_MATH,

Median filtering could help to make the areas more uniform. You'll need to work at optimizing parameters, and maybe eve

Oh geez, It's OpenCV's random installation generator at work again. I've seen that before too. Can you tell what diffe

@berak: Is the exact purpose and function of that flag defined somwhere? Also, do you know if it would be affected by u

PS: I wish there was some definitive doc on all the OpenCV cmake build flags. The most agonizing build process ever.

The build folder was completely clear at the start. Fresh install. I just got as far as the 'configure' process, so I d

What does cmake/make do with Python folders designated during build I'd like to get a better idea of what cmake is doing

Still thinking about going this route, given that virtual envs are the thing these days. If I build OpenCV with a refer

Understandable. I could have been more clear. Your comments about ldconfig are still helpful, as I don't always get fi

I'd still like to know: This is a duplicate of -which- question?

If this is closed as a duplicate, isn't it normal practice to add a link to the original post that answers the question?
