But this output many stuff to the output. I can silence part of it by

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.
Looks like the problem is in numpy/distutils/exec_command.py and numpy/distutils/log.py. In particular, it looks like a logging problem and I'd guess it may be connected to the debug logs. Also, looks like numpy.distutils.log inherits from distutils.log, which may be obsolete. You might get some control of the log with an environment variable, but the function itself looks largely undocumented. That said, it should probably be printing to stderror when run from the command line.

In numpy/distutils/__init__.py line 886  try changing log.set_verbosity(-2) to log.set_verbosity(2)
