Can't use face_recognition cli

• face_recognition version:
• Python version:
• Operating System: Fedora 28

Description

I've just installed face_recognition and dlib. When I run this command below, I get that output.

face_recognition ~/people_i_know/ ./unknown_people/

What I Did

I tried to install dlib 19.7. I downloaded it from sourceforge.net and tried to compile according to this:

Start by reproducing the face_recognition command on Fedora 28 and inspect the reported Python 2.7 package environment. Check the installation path and dependency metadata for face_recognition and dlib; done means the CLI starts and processes the supplied image directories without the DistributionNotFound error.
