How does one load data into the local Development Server using Python?

I know this is covered amply in the GAE help site. It's not working out for me. I'm a little green on Python. But I also know how imports work. The entities module is right there in the same folder with the loader. So what are the GAE scripts doing?

Here's my loader:

from google.appengine.ext import db
from google.appengine.tools import bulkloader
import entities

class CardLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Card',
            [('english', str),
            ('translation', str)
            ])

loaders = [CardLoader]

Here is what is in a file called entities.py

from google.appengine.ext import db

class Card(db.Model):
    english = db.StringProperty(required=True)
    translation = db.StringProperty(required=True)

Here's a snip of what's in the .csv

"cardId","english","translation"
"3994","face","la cara"
"4027","art","el arte"

My version of Python:

Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

Here's my command (on Windows):

python "c:\Program Files\Google\google_appengine\appcfg.py" upload_data --config_file=card_loader.py --url http://localhost:8080/remote_api --filename=card_data.csv --kind=Card

Here's the output:

ImportError: No module named entities

The traceback describes a ImportError: the module entities wasn't found. Is that where your models are? If so, you must be sure it can be found (add its directory to sys.path if needed).
