Flask-API needed
Hi, I am trying this great app. But when I followed the guide, I got an error:
→ python2 web.py
Traceback (most recent call last):
File "web.py", line 1, in <module>
from flask.ext.api import FlaskAPI
File "/Users/chet/anaconda/envs/crec/lib/python2.7/site-packages/flask/exthook.py", line 87, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.api
I find a solution from http://www.flaskapi.org/. It seems it depends on Flask-API which only can be installed through pip.
pip install Flask-API
Then, I try again.
→ python web.py

But the link shows:

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
So, is it right way to build the web?
Thank you

Error of redis zadd()
Hi,
Thanks for sharing such useful content based recommendation engine.
When testing your example i get below error
File "sklearn_tfidf.py", line 74, in _train self._r.zadd(self.SIMKEY % row['id'], *flattened) TypeError: zadd() takes from 3 to 7 positional arguments but 198 were given
Can you please guide me what is going wrong ?
I have latest redis version installed and i am using python3
Error while running web.py
