Update __init__.py

Got a fatal exception on this line, which prevented the generation of the documentation.

The problem is that some variable is initialized in a try bloc but still used out of it afterwards.
If the getattr fails line 682 - which was my problem - then the variable is used without being initialized, which lead to fatal error.
