Illegal Instruction.

• face_recognition version: 0.1.9
• Python version: 2.7
• Operating System: Linux Mint

Description

Hey, first of all Thank you so much for this library. Its Amazing.
When i run the script line by line, i get an error "Illegal Instruction" at the following line
"my_face_encoding = face_recognition.face_encodings(picture_of_me)[0]"
The python terminal exits after this. Please let me know if i am doing something wrong.

What I Did

I am using Linux Mint and i pip installed face_recognition (got all libraries including dlib installed)

The issue is most likely that dlib was compiled with support for AVX and/or SSE4 instructions, but your cpu is too old to support them (pre-2011, I think).

The easiest solution is to download dlib and compile it yourself. But when you do that, you need to make one change.

Before compiling dlib, edit dlib's tools/python/CMakeLists.txt file from:

set(USE_SSE4_INSTRUCTIONS ON CACHE BOOL "Use SSE4 instructions")

to:

set(USE_SSE2_INSTRUCTIONS ON CACHE BOOL "Use SSE2 instructions")

And then compile and install dlib and the dlib python extensions. Hopefully that should fix it.

Correct. My Laptop is from 2008. The solution you suggested has fixed my issue. The script is able to recognize faces. Thank you.

face_recognition version:0.1.0
Python version:2.7.6
Operating System:ubantu 14.04
I encountered the same problem，When i run the code,
I get an error "Illegal Instruction" at the following line
gnss523@gnss523:~/Desktop/face_recognition-master/examples$ python find_faces_in_picture.py
Illegal instruction (core dumped)

[ageitgey]

Did you follow the instructions above?

I try this method

i have got this error ...how to solve it??

` >>>import face_recognition

[ageitgey]

AttributeError: 'module' object has no attribute 'face_recognition_model_v1 means that the version of dlib you are using is too old. You need to use dlib 19.4 or newer.

Hi ageitgeym
Thanks for putting this togheter.
I've got error Process finished with exit code 132 (interrupted by signal 4: SIGILL)
when I run the examples, I also cheked if my processor was SSE4 capable (Intel® Xeon® Processor W3680) so before downloading dlib and compiling I wanted to know if there's something else I should do.

thanks for reading and your vmmachine

[ageitgey]

@Forsskieken The Intel Xeon W3680 (released 2010) doesn't support AVX instructions (released 2011). So that's why it's failing. Sorry! Your only option is to compile dlib without AVX enabled.

Hi There the compilation succeeded but when I want to install it I get following error:

deeplearning@deep-learning-virtual-machine:~/Downloads/dlib-19.4$ python setup.py install
Traceback (most recent call last):
  File "setup.py", line 36, in <module>
    from setuptools.command.bdist_egg import bdist_egg as _bdist_egg
ImportError: No module named setuptools.command.bdist_egg

python3-setuptools is already the newest version (20.7.0-1).

I then did:

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
sudo python3 setup.py install

But how do I make sure pycharms uses this newly compiled version
Ok it seems "sudo python3 setup install" instead of "sudo python setup.." did the trick

Thanks and kind Regards

[ageitgey]

@Forsskieken The problem was python setup.py runs Python 2, which is totally separate and doesn't have access to any libraries you installed for Python 3. So running python3 setup.py instead is the key.

You can choose when version of Python you are using in Pycharm by going to your project settings and changing the interpreter it's using. Just make sure you choose Python 3 for any new projects you create.

I am getting error like this..

from .api import load_image_file, face_locations, face_landmarks, face_encodings, compare_faces, face_distance

[ageitgey]

@PreethiRe Please don't post on closed issues with new unrelated problems. In any case, the answer to your question is here in the README. You need to upgrade to a newer version of dlib.
