I want to use pykaldi with python 3.12 . Unfortunately, there is no precompiled wheel, so I have to build it myself.
Problems:

1. tools/install_kaldi.sh don't work because it requires python 2.7
   Solution: in kaldi/tools/extras/check_dependencies.sh , line 93:

 pythonok=true
if ! have python2.7; then
  echo "$0: python2.7 is not installed"
  add_packages python27 python2.7
  pythonok=false
fi

I remove everything except line pythonok=true . After that, it installs without any problems.

2. python setup.py test fails because with errors on of old testing infrastructure, line tests_requre=['pytest'] in setup.py, etc.
   Solution: Fresh setuptools package deprecate something used here. I downgrade it with:
   pip install --upgrade 'setuptools<72'

3. Some tests with python setup.py test are failing with errors in numpy. It's because of numpy>=2.
   Solution: Looks like it's easy to update code to numpy>=2, but I decide to not take this risk:) So I just downgrade numpy to 1.x:
   pip install --upgrade 'numpy<2'
