kaldi failed: MKL libraries could not be found

[Sray Chen]

Hi all,

After I run ./extras/install_mkl.sh, I accidentally delete the /opt/intel/ directory.

And now, even I got message: ./extras/install_mkl.sh: MKL package intel-mkl-64bit-2019.2-057 was successfully installed, the ./extras/check_dependencies.sh will still give message:  Intel MKL is not installed

Anyone knows how to fix it?

The installation log for mkl is:
'''

I'd remove and then add the package, e.g.

apt-get remove  intel-mkl-64bit-2019.2-057 

apt-get install intel-mkl-64bit-2019.2-057 

(not sure if it's delete or remove).

Hi,

The apt-get remove intel-mkl-64bit-2019.2-057 didn't work.
The install_mkl.sh should create a directory /opt/intel/. But after following steps:
1. apt-get remove intel-mkl-64bit-2019.2-057

2. removing kaldi

3. git clone kaldi 

The ./extras/install_mkl.sh still can't create /opt/intel/ and give the message "MKL package intel-mkl-64bit-2019.2-057 was successfully installed", which will cause ./extras/check_dependencies.sh still think MKL is not installed.

I don't know, you may have messed up the system in such a way that it confused Intel's installation script.  Kaldi's own script doesn't do anything more than call the system installer and check its output.

I can't help much more.
