I encounter the following error on importing pocketsphinx python module

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "sphinxbase.pxd", line 138, in init pocketsphinx (pocketsphinx.c:6695)
ValueError: PyCapsule_GetPointer called with invalid PyCapsule object

But when I import pocketsphinx module once again in the same instance of Python interpreter, it works.

    I am getting a similar problem

    This error occured for me when running python 2.7.3
    I installed python 2.6.8, recompiled sphinx base 0.7 and pocketsphinx 0.7 (make clean first) and ./configure --with-python=/path/to/python2.6/bin/python
    This seems to have fixed the problem for the time being.

    This is unlikely a pocketsphinx problem. Something got broken on python or cython. If you want to help go to cython developers and ask them what is going on.

    The C source files emitted by Cython need to be regenerated and then sphinxbase and pocketsphinx need to be rebuilt to correct the exception on import.

    Delete 'python/sphinxbase.c' from the sphinxbase source directory and delete 'python/pocketsphinx.c' from the pocketsphinx source directory. Make sure Cython is installed so these files can be regenerated.

    Next, just ./configure, make clean all, and make install as outlined in each README. Your version of Cython will be invoked to regenerate the files you deleted.

    Thanks, Anonymous. I was experiencing this issue and your solution worked for me! :)

    Also don't forget that if you ran

    python setup.py install
    

    prior to removing the files as stated above, you will have to run that again after recompiling.

    I encountered a similar problem (Windows 7 64-bit, Python 2.7.3 32-bit).

    Following the steps proposed by Anonymous, import ok now.

    However, just like
    https://sourceforge.net/p/cmusphinx/discussion/help/thread/ddb855bc/#ed45
    when trying to decode_raw(), Python crashed without any info.

    What could be the possible reason?

    BTW, this is the first time I compile a python package from source. Are there pre-compiled binaries for the python binding of pocketsphinx in Windows?

    Thanks for any information.

    Sphinxbase and Pocketsphinx are now using SWIG instead of Cython. So this bug is not relevant anymore.

    @Anonymous
    I am having the same PyCapsule error when importing pocketsphinx on windows. I have Python 2.7.3, Windows 7 32 Bit and I have installed sphinxbase 0.8 and pocketsphinx 0.8 using Visual Studio 2010 and there were no errors during the compilation of the source.
    Regarding the regeneration of C source using Cython, how am I supposed to that on Windows?

    Hello, I tried what Anonymous described in https://sourceforge.net/p/cmusphinx/bugs/284/#b6ea
    But I am still getting the same error. I am using Mac OSX 10.9.2

    import pocketsphinx
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "build/bdist.macosx-10.9-x86_64/egg/pocketsphinx.py", line 7, in <module>

    File "sphinxbase.pxd", line 150, in init pocketsphinx (pocketsphinx.c:7935)
    ValueError: PyCapsule_GetPointer called with invalid PyCapsule object

      Hello William

      The fix will be available in the next release. If you want to access it now, you need to checkout development version from subversion or download a snapshot from github:
