Python doesn't recognize the Decoder from pocketsphinx

Question

I have installed the latest versions of pocketsphinx and sphinxbase (0.8). I try to import pocketsphinx into python code (version 3.4.2 of Python) and to use the "Decoder" like this:

try:
    import sphinxbase
    import pocketsphinx as ps

except:
    print ("Pocket sphinx and sphixbase is not installed in your system.
Please install it with package manager.")

speechRec = ps.Decoder(hmm = hmmd, lm = lmdir, dict = dictp, beam = '1e-80')
wavFile = file(wavfile,'rb')
wavFile.seek(44)
speechRec.decode_raw(wavFile)

However, I get the following error:

AttributeError: 'module' object has no attribute 'Decoder'

Does somebody know what's wrong?

Have you named your file `pocketsphinx.py` or any other file in the pwd as `pocketsphinx.py` — Bhargav Rao, Jan 08 '15 at 18:56

As Bhargav has already mentioned, you have named your file pocketsphinx.py or have a pocketsphinx.py in your path so you need to rename the file and make sure to delete the pocketsphinx.pyc file also. You are trying to import from that file not the pocketsphinx module.

I didn't name any file like that in the path. But maybe I'm missing something: pocketsphinx.pyx & pocketsphinx.pxd are equivalent to pocketsphinx.py? – AdiKatz12 Jan 09 '15 at 15:57
do you have ipython installed? – Padraic Cunningham Jan 09 '15 at 16:03
also what does `import pocketsphinx; pocketsphinx.__file__` output? – Padraic Cunningham Jan 09 '15 at 16:25
/usr/local/lib/python2.7/dist-packages/pocketsphinx-0.0.4-py2.7-linux-x86_64.egg/pocketsphinx/__init__.pyc – Arti Apr 12 '15 at 19:19
Ok but you say in your question you are using python3 but it shows yiou have it installed for python2? – Padraic Cunningham Apr 12 '15 at 19:39

I ran into that same issue again and could solve it for me. Just for anyone who has this problem in the future, too:

First, I installed a pocketsphinx release from http://downloads.sourceforge.net/cmusphinx/pocketsphinx-5prealpha.tar.gz. The corresponding swig/python/__init__.py which gets installed to /usr/lib/python<ver>/site-packages/pocketsphinx/__init__.py contains the following:

from pocketsphinx import *

When I install pocketsphinx from https://pypi.org/project/pocketsphinx/, the corresponding __init__.py contains:

from .pocketsphinx import *

It seems that the tiny dot makes the difference if an import statement like from pocketsphinx import * works or if you have to use from pocketsphinx.pocketsphinx import *
