Lots of things.

(1) Check the spelling. Python is case-sensitive, so SOMFactory is not 
the same as SomFactory or SOMfactory or somfactory.

(2) Do you have your own file called "sompy.py" somewhere? If so, that 
will block access to the real one.

(3) Are you sure that sompy supports Python 3.5?

(4) Are you sure that SOMFactory actually exists? I don't see it in any 
of the five notebooks here:

https://github.com/sevamoo/SOMPY

although maybe I've missed something.


It might help if you can copy and paste the FULL traceback showing 
exactly what line of code failed and the precise sequence of calls. 
Please COPY and PASTE (don't retype from memory, or summarise, and 
especially don't take a screenshot) the entire traceback, starting with 
the line 

Traceback (most recent call last):

all the way to the end. Then we will have a better idea of what is going 
on.
