DLib {#dlib} #

DLib is a modern, C++-based toolkit which provides several machine learning algorithms.

Compiling without AVX support {#compiling-without-avx-support} #

Especially older CPUs don't support AVX (Advanced Vector Extensions) instructions that are used by DLib to optimize their algorithms.

On the affected hardware errors like Illegal instruction will occur. In those cases AVX support needs to be disabled:

self: super: { dlib = super.dlib.override { avxSupport = false; }; }
