Problem with running the swarm in the HotGym example on windows

After installing Nupic on my Windows OS i tried to follow the HotGym example but i am running into problems when running swarm.py

this is the output i get when i run swarm.py:

D:\a\nupic hot gym>python swarm.py
This script runs a swarm on the input data (rec-center-hourly.csv) and
creates a model parameters file in the `model_params` directory containing
the best model found by the swarm. Dumps a bunch of crud to stdout because
that is just what swarming does at this point. You really don't need to
pay any attention to it.

= Swarming on rec-center-every-15m-large data...
= Medium swarm. Sit back and relax, this could take awhile.

one thing i noticed is that in the error message where it tells me the path of the file its trying to read the filename has // instead of the regular /

has somebody here run into similar problems before and could help me figure it out?

*edit: removed &#65279 i added manually because of formatting issues

This file path looks wrong.

okay in the swarm.py file i speficied the path like such: INPUT_FILE = “D:\a\nupic hot gym\rec-center-every-15m-large.csv”

now the error i get looks like this: IOError: [Errno 2] No such file or directory: u’D:\ \a\ \nupic hot gym\ \ter-every-15m-large.csv’

i had to add spaces between the \ or the css formatting of this reply form makes them dissapear

i have no idea where the double \ and the u’ are coming from

It seems you new to python, right? I suggest you look up how to read and write files in python and practice with some local files to make sure you can do it. I think is still just a simple file path error.

I forgot to specify the file path in swarm_description.py, it is working now.
My bad sorry for wasting your time on such a simple error.
Yes i am new to python i am learning it because i want to play around with nupic.

The same problem is happening on my MAC system as I am being unable to have the access of the iTunes because the swarm on the MAC is not supporting and it is getting iTunes error 9

@tommyshelby Hi and welcome to HTM Forum! Thanks for your question. I have never seen that error before. Can you tell me the exactly command you ran that cause the error?
