Dlib: Running dlib with cuda support.

[patrickacole]

How do I enable dlib with cuda support? I installed dlib through pip. Thank you!

Try installing the latest dlib from github. It should print out more detailed messages about CUDA usage than the copy of dlib in pip. That will help you get it working with CUDA.

I tried installing dlib with cuda support but encountering OpenMP missing error while installing:

I fixed this exact error by running
brew install llvm

Apparently OpenMP is installed alongside llvm.

@smitshilu ,
Help!
First, thank you for your post.
I looked all over for the install with CUDA command

I got the build files written.
I ran 'make'
I ran 'sudo make install'
But I'm not sure my application using dlib is running on the GPU. Actually, mostly sure it's not.
When I run 'nvidia-smi' while my process is running it displays that the GPU is NOT being used by the process.

Are there other steps to take after the steps I took that I am missing?

If you are waiting for a response but haven't received one it's likely your question is somehow inappropriate. E.g. you didn't follow the issue submission instructions, or your question is easily answerable by reading the FAQ, dlib's documentation, or a Google search.
