I am running a large
from module import *
[u'Brewer and Shipley']
While blowing to find out who blew is excellent suggestion by @FMc, Here is another trick I use
print 'X imported'
print 'Y imported'
print 'Z imported'
This will also help you narrow down module with a problem. :)
You can optimize this by doing binary search by printing middle points, but I guess that's over-engg.
