I want to know if and where LAPACK, BLAS, ATLAS packages are installed. I have been reading that these libraries speed up data crunching with numpy(python).
How can it find the location of these packages (if they are installed) and turn them off?
on linux you can do this
apt-cache policy liblapack3
apt-cache policy libblas3
apt-cache policy libatlas-base-dev
and for the lapack, you will get
liblapack3:
