same dlib python version get different performance
I installed dlib 19.16.0(pip install dlib==19.16.0 in python 2.7.12), but I found the correlation_track performance downgrade(30 FPS->20FPS), then I checked another machine which I installed couple days ago, that one is good!
I run 'pip freeze', both of them are dlib 19.16.0, but with different file size:
the slower one: 10940368
the faster one: 11660480
after I replace the slower one(which is in lib/python2.7/site-packages/dlib.so), the performance back to 30fps, so looks the problem is in dlib
I also tried to download latest dlib.tar.gz(19.16.0) from dlib.net, then run 'python setup.py install', however this doesn't help (http://dlib.net/compile.html)
both machine's hardware spec are same, but with different gcc:
slower one:
4.15.0-39-generic #42~16.04.1-Ubuntu SMP Wed Oct 24 17:09:54 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
gcc version 4.9.3 (Ubuntu 4.9.3-13ubuntu2)
faster one:
4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
is it compile issue?
python gcc dlib
