Trouble Installing OpenFace in Python

Question

I am new to deeplearning and face recognition. After searching, I found this python package about deeplearning applied to face recognition called OpenFace. From its documentation, I think it is build on top of Torch for the neural nets computation.

I want to install the package in a virtual environment, so basically these are steps I made:

1. brew install the necessary system requirements: bash,coreutils,curl,findutils,opencv, python and boost-python
2. Make a virtual environment and install dlib, numpy, scipy, pandas, scikit-learn, scikit-image
3. Cloned the openface github repository

4. Install Torch

   curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash git clone https://github.com/torch/distro.git torch --recursive cd torch ./install.sh source install/bin/torch-activate luarocks install csvigo luarocks install dpnn luarocks install nn

5. cd to cloned openface repo and run python setup.py install

However when I run python:

>>>import openface

I get:

Segmentation Fault: 11

How do I fix this? Also, are there any other tutorials for using openface? How to properly install OpenFace?

Answer 1

As I posted in the comments, this segfault was caused by compiling dlib with one Python version and running it with another. This was resolved by manually installing dlib rather than using their pip package.
