The first thing I would do is try to figure out if it's happening in the
join() or the open(). Try refactoring this as:
> temp = os.path.join(root, file)
> with open(temp, 'r') as f:
and see which line generates the exception. I'm guessing it's the
join(), but it helps to make sure (so you don't go down some rabbit
hole). Next, I would try to construct a minimal test case. Keep
hacking away code until you get down to the smallest thing which is
produce the problem. I'm guessing something like:
> for root, dirs, files in os.walk('./'):
> for file in files:
> os.path.join(root, file)
might do it. Hopefully that will narrow things down a bit.
