Hi,
my application frequently requires to take logarithms of zero, i.e.
import numarray numarray.log(0.0)
Warning: Encountered divide by zero(s) in log -inf
Now, while the result of -inf works just fine, any direct application of numarray.log produces tons of warnings. Right now I'm masking the input arrays to avoid the warnings, which is rather inefficient.
So, the question is whether there is some kind of verbosity control I could use to deactivate these warnings. If there is no such functionality, I would like to suggest looking into the build-in Python logging package for that purpose.
Best, Benjamin

Yes, look at section 6.2 of the numarray manual.
