Hi,
I am having a problem with some python code which runs perfectly in
straight python, bout fails inside sage, with the following error
message:
Traceback (click to the left for traceback)
...
TypeError: array cannot be safely cast to required type
Traceback (most recent call last):

the code snippet is:
from BIP.Bayes import lhs
d = lhs.lhs(stats.randint,(0,15),(10,10))
BIP is a package which is in PyPI and can be easy_installed. for this
test I installed it manually inside sage by copying the package
directory to sage's site-packages directory.
I running this code with preparser turned off: preparser(False)
