Labelsbug

What Operating System(s) are you seeing this problem on?

Linux (x86-64)

dlib version

19.24.2

Python version

3.11.3

Compiler

boost-1.81.0-6 cmake-3.26.4-1 gcc-13.1.1-1 archlinux

Expected Behavior

Can be installed successfully and be able to use CUDA acceleration

Current Behavior

Unable to install a Dlib instance that can be accelerated by Cuda

Steps to Reproduce

Download the release archive, unzip it
Install Dlib supported by Cuda Run the command python setup.py install --set USE_AVX_INSTRUCTIONS=1 --set DLIB_USE_CUDA=1
Error

Anything else?

python setup.py install --set USE_AVX_INSTRUCTIONS=1 --set DLIB_USE_CUDA=1
