Re: [Kaldi-developers] Problems in installing Kaldi

[Arnab G. <ar...@gm...>]

Kaldi needs some kind of linear algebra library. ATLAS is easily
obtained. Otherwise if your system has MKL, you could use that as
well. Check to see what messages install_atlas.sh generated (btw, you
are using an older version, since the install_atlas.sh has now moved
to tools/extras). The most common problem is that CPU throttling needs
to be disabled for installing ATLAS, but that requires root access. It
may be best to consult with your admin about ATLAS/MKL and to install
one if none is present.
