Error Matlab Compiler SDK Python

I've followed the tutorial on mathworks website on starting with the Compiler SDK for Python. I've already compiled the makesqr function that I want to call from Python but I have this error :

>>> makesqr.initialize()

Undefined function or variable 'setInitialWorkingFolder'.

Error in matlabrc (line 197)

Traceback (most recent call last): File "<stdin>", line 1, in module

File "/usr/local/lib/python3.4/site-packages/translator/__init__.py", line 301, in initialize

    return _pir.initialize_package()

File "/usr/local/lib/python3.4/site-packages/translator/__init__.py", line 249, in initialize_package

    package_handle.initialize()

If someone can give me some help i'll be really grateful.
