I have CUDA 9.0 and CUDNN 7.1 installed on Ubuntu 18.04(Linux mint 19). Tensorflow-gpu works fine on GPU(GTX 1080ti).
Now i am trying to build dlib with CUDA support:
sudo python3 setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA --clean
Got the error:
user@user-pc:~/Downloads/dlib$ sudo python3 setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA --clean
