What I Did
workon test (or mkvirtualenv test before)
pip install face_recognition
dlib (19.16.0) md5sum : 96ff1db547ab5d289d049e58f823ae46
Temporary solution
Install dlib version 19.15.0
pip install dlib=19.15.0
dlib (19.15.0) md5sum : e0ea6c4c6e7c1f445a11fae2733cb9b6
Additional comments
A word about Archlinux, if you do yay -S python-face_recognition
, it will work, but it won't be in a virtualenv. Please do not close this issue if we can't do pip install face_recognition
normally to his latest version. Thanks.
I encountered the same problem on antergos with dlib 19.17.0. The solution for me was installing cblas via pacman
I had a similar problem. Solved it by installing openblas. On arch just: pacman -S openblas And then, reinstalling dlib.
pacman -S openblas
thank you for recipe. I tried that but had another experience:
pacman -S cblas
# and reinstalling dlib
(pip) -- successfully fixed the issue (but with a regular blas
, not openblas
).
but just changing blas
with openblas
(without a cblas
) -- did not helped
I have the same problem on arch and ended up installing dlib 19.15.0 as mentioned previously.
pip install dlib==19.15.0
work
As suggested by @antonov-impulsm with https://github.com/ageitgey/face_recognition/issues/731#issuecomment-775988894 I just solved installing both openblas
and cblas
and then reinstalling dlib
using pip
.
Thanks man
