Newest version of py-kaldi-asr (0.5.0) fails on missing README.md file:
File "/tmp/pip-build-gatbmr8h/py-kaldi-asr/setup.py", line 112, in
long_description = open('README.md').read()
W/o it pip install fails all the time
ImportError: libkaldi-decoder.so: cannot open shared object file: No such file or directory.
Can you share simple steps to do on ubuntu 16.04 && g++ 5.4.0 to run the basic demo?
When running your nnet3_online.py example, I get the following error:
Traceback (most recent call last):
File "py-kaldi-test.py", line 21, in <module>
kaldi_model = KaldiNNet3OnlineModel (MODELDIR, model)
File "kaldiasr/nnet3.pyx", line 52, in kaldiasr.nnet3.KaldiNNet3OnlineModel.__cinit__
File "stringsource", line 15, in string.from_py.__pyx_convert_string_from_py_std__in_string
TypeError: expected bytes, str found```
The file setup.py imports numpy
at the top, but this will fail if numpy
isn't installed on the system yet. So a simple pip install py-kaldi-asr
is not possible on a newly set up Python environment. But adding numpy
to install_requires
won't help either, because pip
runs setup.py
to find out the package's requirements.
There seem to be solutions, but they're not clean (see How to Bootstrap numpy installation in setup.py
).
Maybe you can mark this issue as low priority.
Hi,
when passing a long wave or stream to the decoder, how to detect multiple sentences inside of the audio signal?
hi guys
when I trying to decode the chain model, there is a error and how fix it ?
ERROR ([5.4.155~1399-fdd8]:DecodableNnetLoopedOnlineBase():decodable-online-looped.cc:45) Input feature dimension mismatch: got 40 but network expects 43
Hi,
I tried to run your code. I succeed to get nnet3.so file. Then, I tried to run examples/nnet3_online.py but I get the following error:
Traceback (most recent call last):
File "examples/nnet3_online.py", line 32, in
from kaldisimple.nnet3 import KaldiNNet3OnlineDecoder
ImportError: No module named kaldisimple.nnet3
Do you have any idea about this?
Hi,
Im running ubuntu 18.04, with python2.7.17 and have setup Kaldi as per the installation instruction available in their website. When I try to run your example application, python kaldi_decode_wav.py -v demo?.wav
, I'm getting the below error. Kindly help to resolve this.
Traceback (most recent call last):
File "kaldi_decode_wav.py", line 36, in <module>

It's very convenient to be able to install py-kaldi-asr
with pip install py-kaldi-asr
. But how can I get the source code for a specific version of py-kaldi-asr
? It would be nice if there'd be releases under https://github.com/gooofy/py-kaldi-asr/releases so that the version numbers correspond to the versions on PyPi.
If you don't want to release on GitHub, it would be nice if you'd create tags with the corresponding version numbers as names.
Hello!
I successfully installed py-kaldi-asr. But when I run "examples/nnet3_online.py", I get the following error:

Could you help me with it?
Hi,
I'm installing py-kaldi-asr via pip on condaenv, but I'm getting this error:

I had encountered a similar issue with the .pc file for Atlas, but managed a workaround(as the file was in a different dir) but I'm completely lost at this, mostly because I just got swamped with some other work.
System:
Ubuntu 18.04 on Oracle Virtualbox (Host Windows 8)
Python 2.7 (Anaconda) (but I'm using "pip" for this and not "conda")
Thanks!(This is my first git issue ever)
unnecessary comment: What's the deal with pkg-config anyway?
I have followed all the rules and successfully did make without any error but i got a few warnings

If this is an issue please do tell me where I am going wrong, because when I run an example file line chain_online.py I get this,

Hi,
I would like adding a new word, but this word doesn't exist in CMU pronounce dictionary. So I used logios lexicon tool to generate a new pronunciation dictionary. I would like to know how to add this new dictionary to the existing model? Thank you so much.
Guenter,
Thanks for your work, I successfully compiled and tested your code. And also I can do decoding using your pre-trained model (kaldi-generic-en-tdnn_f-r20190609) now. Great work!
Meanwhile, I am learning Kaldi, and almost finished my first model building using one of Mandarin recipes (aishell). And I just want to know whether it is possible to run decoding task using your code with my own model?
My model is a chain model which was built following the standard recipe (kaldi/egs/aishell/s5/local/chain/run_tdnn.sh)
One possible difficulty I realized is how to collect all the needed data files into model directory, please advice if there is a instruction document on which files are needed and the corresponding source directory of kaldi. By reading your code, seems just collect all the files mentioned in the following code:
****cdef unicode mfcc_config = u'%s/conf/mfcc_hires.conf' % self.modeldir
cdef unicode word_symbol_table = u'%s/%s/graph/words.txt' % (self.modeldir, self.model)
cdef unicode model_in_filename = u'%s/%s/final.mdl' % (self.modeldir, self.model)
cdef unicode splice_conf_filename = u'%s/ivectors_test_hires/conf/splice.conf' % self.modeldir
cdef unicode fst_in_str = u'%s/%s/graph/HCLG.fst' % (self.modeldir, self.model)
cdef unicode align_lex_filename = u'%s/%s/graph/phones/align_lexicon.int' % (self.modeldir, self.model)**
**self.ie_conf_f.write((u"--cmvn-config=%s/conf/online_cmvn.conf\n" % self.modeldir).encode('utf8'))**
self.ie_conf_f.write((u"--ivector-period=%d\n" % online_ivector_period).encode('utf8'))
**self.ie_conf_f.write((u"--splice-config=%s\n" % splice_conf_filename).encode('utf8'))**

self.ie_conf_f.write((u"--global-cmvn-stats=%s/extractor/global_cmvn.stats\n" % self.modeldir).encode('utf8'))
self.ie_conf_f.write((u"--diag-ubm=%s/extractor/final.dubm\n" % self.modeldir).encode('utf8'))**
**self.ie_conf_f.write((u"--ivector-extractor=%s/extractor/final.ie\n" % self.modeldir).encode('utf8'))**
self.ie_conf_f.write((u"--num-gselect=%d\n" % num_gselect).encode('utf8'))
self.ie_conf_f.write((u"--min-post=%f\n" % min_post).encode('utf8'))
self.ie_conf_f.write((u"--posterior-scale=%f\n" % posterior_scale).encode('utf8'))
self.ie_conf_f.write((u"--max-remembered-frames=1000\n").encode('utf8'))
self.ie_conf_f.write((u"--max-count=%d\n" % max_count).encode('utf8'))
self.ie_conf_f.flush()**
Could you kindly elaborate a little about the source directory of those needed files?
Thanks!
Kelvin

There are no kaldi-*.so files in kaldi root. How to complie. Who can help me!
Is it possible to enable CUDA acceleration for decoding a wav file with KaldiNNet3OnlineDecoder?
The reason for asking is that the metric of lattice oracle accuracy (i.e. best accuracy achieved by any path in the lattice) is for some use cases much more useful than word error rate (WER) or sentence error rate (SER). Such use cases are: rescoring lattice with dialog history, rescoring lattice with parsing results etc.
the setup.py document I can not function and I find the package kaldi-arc.pc that it is unrelated to the nnet3.cpp

Why is it so strange to compile "nnet3.c"?
What is a quick way to get atlas installed on Max OSX?
I cloned the repo and encountered the "can't find atlas package" error while making.
I realized that apt install command doesn't work on OSX and couldn't find an equivalent package as libatlas-dev on homebrew, which leads to me following a tutorial to install ATLAS package on my MacBook.
It took me a whole day(around 8 hours) to build ATLAS, yet for some reasons it still lacks the ".so" files (e.g libatlas.so.3). I couldn't find out where I did wrong during build, and really don't want to waste another whole day building/installing atlas...
If there's any quick and clean way to get the atlas package needed to make this repo, please let me know!! Thanks so much
new to this python binding, but i followed the instructions and nnet3.so compiled successfully with kaldi 5.0.
However, when testing, import kaldisimple.nnet3, it shows import error, undefined symbol _ZTVN3fst11SymbolTableE, i already put the tools/openfst/lib into the LD_LIBRARY_PATH, but the issue is still there? anything i am missing? many thanks

Line 199 in a4e5b1e
When using kaldi directly I've been able to pass --frame-shift=0.03
for a chained model to get the correct timestamps for word alignment. Right now it looks like calling get_word_alignment
returns arrays of integers which can just be divided by 100 to get the same value as I would get from calling nbest-to-ctm
directly. I'm not seeing how I can pass in frame shift value though.
Any thoughts?

What must it be? Everything has been installed properly. Could you please specify what is going wrong with the package?
I find that I can not use the setup.py
there are some errors in config-pkg
Similar issue as with the model (#36).
decoder n files in a list with

finally:

try:

finally:
del decoder

del decoder
is used. Deleting the model has not effect, since it leaving much bigger leak in the memory (see #36)hi,
i have experienced the atlas issue also.
It is similar to Setup error:cannot find -lsatlas #23
and I think the readme must be updated.
Option 1
add pkg-config
for atlas
- most probably for various systems (in my case I use Ubuntu)
Option 2
skip the atlas
in requirements in pkg-config
for kaldi-asr.pc
thx,

Is it copied from kaldi-asr/src

I have discovered, that memory is leaking by using the model/decoder.
Load model, use it, unload -> the memory is released partially.
