--Updated 11/29/2017
The problem is solved by using older kaldi toolkit (the version committed on 9/9/2017).

--Original
First sorry for my poor English.
I'm trying to install kaldi-python, but I received compiling errors(see below) when making. I don't know whether it is because I'm using the wrong boost library, which I installed with sudo apt-get libboost-dev-all.
And the GCC version I'm using is 5.4.0(on Ubuntu 16.04).

Sincerely.

The errors are like:

Hi,

I am trying to use kaldi-python for python3.6. I am able to compile and import kaldi_io, but when I try to use it, there's some error:

--> import kaldi_io
--> ali_reader = kaldi_io.SequentialInt32VectorReader(align_scp)
Boost.Python.ArgumentError: Python argument types in
SequentialInt32VectorReader.init(SequentialInt32VectorReader, str)
did not match C++ signature:
init(_object*, std::__cxx11::basic_string<char, std::char_traits, std::allocator >)

Would you please tell me how to solve this? Thanks a lot!!!

Hello Jan

Thanks for sharing your valuable code.

Recently, I was trying to port your code into python 3.4 because I want to work in Keras. In order to work in 3.4, I changed library setup in Makefile in kaldi_io directory as follows:

...
PYLIB = $(shell python3-config --libs)
PYINC = $(shell python3-config --includes)
NPINC = -I$(shell python3 -c 'import numpy; print(numpy.get_include())')
...

after python3 setup.py install, I confirmed packages are successfully installed in python3.4 dist-packages directory. However, when I import kaldi_io package in python3, it showed following errors:

Python 3.4.3 (default, Nov 17 2016, 01:08:31) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import kaldi_io
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.4/dist-packages/kaldi_io/__init__.py", line 243, in <module>
    from kaldi_io_internal import *
ImportError: /data/userdata/jaey1.kim/tools/jaey_dev/kaldi-python/kaldi_io/kaldi_io_internal.so: undefined symbol: _ZNK5boost6python7objects21py_function_impl_base9max_arityEv

I used nm to find the unknown symbol and it turns out to be:
U boost::python::objects::py_function_impl_base::max_arity() const
and I'm stuck. I guess it is related to boost library. I installed latest boost library but still it happened.

Could you give me any advice to port it into python 3.4? I would be really appreciating it.

Thanks

Hi,
ubuntu 14.04.
use thi command(.setup.py install) to setup kaldi-pthon, I have set $KALDI_ROOT already
the errors are as follows:

thse errors seem to happen in creating kaldi_io_internal.so, if I don't use these .a file $(KALDI_SRC)/matrix/kaldi-matrix.a $(KALDI_SRC)/util/kaldi-util.a $(KALDI_SRC)/base/kaldi-base.a ,
kaldi_io_internal.so can create(of course this file can't be used)
I try to install this package kaldi-python on ubuntu,Centos, but failed.......

I am sure that I installed the newest kaldi, could that be the cause of the this problem? Does kaldi-python requires older verison of kaldi?
Best

Many thanks

Dear Jan,

I am working on acoustic modeling using python.
Recently I came across kaldi ASR toolkit and your modules to read kaldi ark files into python.
I am trying to install kaldi-python, but it gives the following error:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [kaldi_io_internal.so] Error 1
make: *** [all] Error 2

I am using Mac OS X Yosemite 10.10.3.
However, I am able to install kaldi (trunk, without python) and run the /egs scripts successfully, but do not know how to read/write the features (ark, scp) with my python codes.

Sincerely,
-Vipul

A vector such as [[ 1. 0. 0.]] gets coded into kaldi matrix as [0 -inf -inf ]

Why? and how do i fix it?

import kaldi_io
Traceback (most recent call last):
File "", line 1, in
File "kaldi_io/init.py", line 243, in
from kaldi_io_internal import *
ImportError: kaldi_io/kaldi_io_internal.so: undefined symbol: _ZN5kaldi9SemaphoreD1Ev
when I import kaldi_io, I encountered the problem. Could you help me solve it, thank you very much.
I rebuilt the kaldi with configure --share, and I also add the kaldi_io_internal.so to /anaconda3/lib/python3.5/site-packages/
