[Numpy-discussion] Silencing NumPy output

[Frédéric Bastien]

Hi,

NumPy 1.8 removed the private NumPy interface
numpy.distutils.__config__. So a Theano user make a PR to make Theano
use the official interface:

numpy.distutils.system_info.get_info("blas_opt")

But this output many stuff to the output. I can silence part of it by
silencing warnings, but I'm not able to silence this output:

Found executable /usr/bin/gfortran

I tried to redirect the stdout and stderr, but it don't work. I looked
into NumPy code and I don't see a way to change that from a library
that use NumPy.

Is there a way to access to silence that output?

Is there a new place of the old interface: numpy.distutils.__config__
that I can reuse? It don't need to be a public interface.

thanks

Frédéric
