# 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)

## Fatal Python error: PyThreadState_Get: no current thread

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')
