error during compilation

[rohithkodali]

hi,

i'm trying to follow the installation procedure but when i try "make" it is throwing some errors like

/home/rohit/speech/development/speaker_verification/PLDA/src/kaldi-utils.hpp:101:26: error: 'PyArrayObject' has no member named 'dimensions'

/home/rohit/speech/development/speaker_verification/PLDA/src/kaldi-utils.hpp:101:26: error: 'PyArrayObject' has no member named 'desc'

etc, there are some other issues like this, i don't think these are because of ATLAS, is there anyway to solve it and my numpy is of updated version

Can you provide the whole output of your make? I'm pretty certain it's numpy/ scipy.

here is the complete make log log.txt

Alright, you dont run the script in an venv, do you? Otherwise could you check for ndarraytypes.h just run something like locate ndarraytypes.h | head -n 1 | xargs cat | grep "dimensions"

That should find the dimensions attribute in the pyarrayobject. If that doesn't please check if you still have multiple installations of numpy. Lastly make sure its python 2.7 youre compiling with

i use a ubuntu desktop not a virtual env and i use python 2.7

the output for above command is

• There are several places in the code where an array of dimensions
• The array creation itself could have arbitrary dimensions but all /* The number of dimensions, also called 'ndim' / npy_intp dimensions;
• I.e. dimensions for which ndarray.shape[dimension] == 1 are /* Require that the dimension match the iterator dimensions exactly _/ int ndm1; / number of dimensions - 1 _/ npy_intp dims_m1[NPYMAXDIMS]; / ao->dimensions - 1 _/ npy_intp dimensions[NPYMAXDIMS]; / dimensions _/ npy_intp dimensions[NPYMAXDIMS]; / dimensions _/ int ndm1; / number of dimensions - 1 _/ npy_intp dims_m1[NPYMAXDIMS]; / ao->dimensions - 1 _/ npy_intp dimensions[NPY_MAXDIMS]; return ((PyArrayObject_fields )arr)->dimensions; return ((PyArrayObject_fields )arr)->dimensions[idim];

  define PyArray_DIMS(obj) (((PyArrayObject_fields *)(obj))->dimensions)

  return ((PyArrayObjectfields *)arr)->dimensions; int nd; / number of dimensions */

I'm pretty sure its your numpy installation. Try to either pip remoev and install or use apt-get for that. If that is failing try to build it using cmake -LAH and check the PYTHON_EXECUTABLE and NUMPY_INCLUDE_DIRS variables. Lastly try to set the NUMPY_INCLUDE_DIRS manually by export NUMPY_INCLUDE_DIRS=YOURPATHTO/INCLUDE/DIRS I'm sorry, I'm unfamiliar with the find Numpy/ Python cmakes that are provided by Cmake itself.

it worked with reinstalling numpy and scipy, thanks a lot.

is there any complete script to use this with kaldi available now?

[RicherMans]

Well partially, I wrote a script used for some of my tasks, which is just pushed to the repository. You can find it in the scoring/ directory. That gives a quick introduction to the PLDA.

Btw since there is not a big documentation about Numpy arrays in C++, please always use uint labels and float data vectors, otherwise the script will malfunction.
