Face_recognition: Installing error

[paulaceccon]

• Python version: 3.6
• Operating sytem: Win 10

Description

I'm trying to install face_recognition. I've already have dlib in my machine, but face_recognition tries to reinstall it and I don't know why or if I can prevent this.

What I Did

It first give me errors with cmake, which I installed. Then, with boost, which I have also installed. I have also set the environment variables which doesn't seem to change the output at all:

CMakeLists.txt:6 (include)
-- Could NOT find Boost
-- Could NOT find Boost
-- Found PythonLibs: C:/Users/paula.ceccon.ribeiro/AppData/Local/Continuum/Anaconda3/libs/python36.lib (found suitable version "3.6.1", minimum required is "3.4")

I wonder if I can somehow "tell" face_recognition that I have dlib in my machine already.

Please see #89. This is the same issue.

The issue is that the Windows conda package for dlib doesn't register itself in a way that pip can see, so it tries to re-install another copy of dlib since it thinks it is missing.

You can work around this by installing face_recognition without automatically installing it's dependencies:

pip install --no-dependencies face_recognition face_recognition_models

But keep in mind that no dependencies at all are installed this way. So if you run into any errors about any missing libraries besides dlib, you might need to manually install those libraries with pip install library_name as well.

after executing the above mentioned command I'm getting this error

import face_recognition
....
ModuleNotFoundError: No module named 'dlib'

I'm also having the same problem ("ModuleNotFoundError: No module named 'dlib'"), tried to install dlib on many different ways, but couldn't make it work

Were you guys able to figure out how to get rid of the "No module named 'dlib'" issue?

For me, I had to remove Anaconda first then do pip install --no-dependencies face_recognition face_recognition_models.
