Hi,
I'm trying to get multiprocessing to working consistently with my
script. I keep getting random tracebacks with no helpful
information. Sometimes it works, sometimes it doesn't.
Traceback (most recent call last):
File "scraper.py", line 144, in <module>
print pool.map(scrape, range(10))
File "/usr/lib/python2.6/multiprocessing/pool.py", line 148, in map
return self.map_async(func, iterable, chunksize).get()
File "/usr/lib/python2.6/multiprocessing/pool.py", line 422, in get
raise self._value
TypeError: expected string or buffer
It's not always the same traceback, but they are always short like
this. I'm running Python 2.6.2 on Ubuntu 9.04.
Any idea how I can debug this?
Thanks!
Erik
