Some build errors in centos7

[v-yunbin]

I need to install ATLAS？

[svenha]

Yes, see https://github.com/gooofy/py-kaldi-asr#atlas

[v-yunbin]

@svenha I install atlas but met follows errors:

python setup.py build_ext --inplace
looking for atlas library, trying pkg-config first...
Package blas-atlas was not found in the pkg-config search path.
Perhaps you should add the directory containing `blas-atlas.pc'
to the PKG_CONFIG_PATH environment variable
No package 'blas-atlas' found
looking for atlas library, pkg-config found it

Maybe your Linux distribution has a usable version of atlas including a .pc file. E.g. Ubuntu has it in package libatlas-base-dev.

If you must rely on your own atlas installation, you must create a blas-atlas.pc file or similar, which is referenced from kaldi-asr.pc (https://github.com/gooofy/py-kaldi-asr#source) BTW: I had to change the Requires line as follows because of Ubuntu's file structure:

Requires: blas-atlas

OK, so I misunderstood the problem you reported and you should investigate the python error message. Your python must by python2.

i go to python2 env, and get some errors as follows:

python setup.py build_ext --inplace

how to set the blas-atlas.pc ? do you have sample?

[v-yunbin]

my atlas.pc:

prefix=/usr
libdir=${prefix}/lib
includedir=${prefix}/include/atlas


Name: atlas
Description: atlas tool
Version: 3.10
Libs: -Wl,-rpath,/usr/lib -L${libdir} -latlas
Cflags: -I${includedir}  -DHAVE_IMMEDIATE_STRUCTURES=1

maybe it have some relation with linux type? No matter i use python3 or python2 , it always raise errors:TypeError: __init__() keywords must be strings

[svenha]

Maybe your kaldi-asr.pc is broken?

[v-yunbin]

but i met another error:
Loading model from model_dir/ ... INTEL MKL ERROR: /home/ybZhang/miniconda2/lib/libmkl_vml_avx512.so.1: cannot open shared object file: No such file or directory. Intel MKL FATAL ERROR: cannot load libmkl_vml_avx512.so.1 or libmkl_vml_def.so.1

I remove the find_dependencies() in Extension， maybe it has same problem in centos：

@svenha rescore is not suppoted? rescore has better performance.
