# Python SDK - Troubleshooting ¶

Here are a few error message you could get, and a possible solution.

## Import error ¶



ImportError: No module named naoqi



You must have something wrong with your  PYTHONPATH  environnement variable. You can check this by typing:



import sys
print "\n".join(sys.path)



You should see  /path/to/python-sdk/lib/python2.7/site-packages  at the beginning of the list.



ImportError: ./_inaoqi.so: wrong ELF class: ELFCLASS32



You are using a 64 bits version of python.



ImportError: libpython2.6.so.1.0: cannot open shared object file: No such file or directory



You are using a Python2.7 with the python2.6 version of the Python SDK.

## Version mismatch ¶



Version mismatch



Your version of Python does not match the one with which the Python SDK was made.

On Mac , make sure  VERSIONER_PYTHON_PREFER_32_BITS  is not set. (While 1.10 needed this parameter ON, release 1.12 needs this parameter to be OFF)

You are using a version of Python that is not binary compatible with the one used to compile the Python bindings.

Make sure you are using Python coming from  Python.org  . (It usually is in  /usr/local/bin/python  )

## Errors with ALProxy ¶



RuntimeError:         ALBrokerProxy::getBrokerInfo
can not get broker info. Endpoint : http://nao.local:9559



Make sure NAOqi is running and the IP you used in  ALProxy  constructor is correct



RuntimeError:         ALNetwork::getModuleByName
failed to get module MyModule http://nao.local:9559



Make sure you spelt the name of the module correctly.



File "naoqi.py", line 246, in method_missing
raise e
RuntimeError:         ALTextToSpeech::sa
ALBroker::methodCall: method: sa, params: ["hello"]
ALTextToSpeech::sa
Function sa does not exist in module ALTextToSpeech



Make sure you spelt the name of the function correctly.

To check the complete list of modules and method names, see section NAOqi APIs

## Weird float errors ¶

If you notice that floats are trucated when they are the result of the call of a bound methods, make sure that your locale is in english.

You can set LC_NUMERIC=’C’ for this



import locale
locale.setlocale(locale.LC_NUMERIC, 'C')
