I would like to import the Tokenizer class located in tokenizer.py script into generate_vocab.py script. Here's my tree view:
 - bin
   - tokenizer
     - tokenizer.py
   - tools
     - generate_vocab.py
What I would like to do is to call something like: from ../tokenizer import tokenizer.py.
Do I need to use a __init__.py script to make my bin/tokenizer directory a module and then call from ... import tokenizer ?
