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 ATLAS version 3.8.3 built by mockbuild on Wed Jul 28 02:12:34 UTC 2010: UNAME : Linux x86-15.phx2.fedoraproject.org 2.6.32-44.el6.x86_64 #1 SMP Wed Jul 7 15:47:50 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux INSTFLG : -1 0 -a 1 ARCHDEFS : -DATL_OS_Linux -DATL_ARCH_Corei7 -DATL_CPUMHZ=1596 -DATL_SSE3 -DATL_SSE2 -DATL_SSE1 -DATL_USE64BITS -DATL_GAS_x8664 F2CDEFS : -DAdd_ -DF77_INTEGER=int -DStringSunStyle CACHEEDGE: 524288 F77 : gfortran, version GNU Fortran (GCC) 4.5.0 20100716 (Red Hat 4.5.0-3) F77FLAGS : -O -g -Wa,--noexecstack -fPIC -m64 SMC : gcc, version gcc (GCC) 4.5.0 20100716 (Red Hat 4.5.0-3) SMCFLAGS : -fomit-frame-pointer -mfpmath=sse -msse3 -O2 -fno-schedule-insns2 -g -Wa,--noexecstack -fPIC -m64 SKC : gcc, version gcc (GCC) 4.5.0 20100716 (Red Hat 4.5.0-3) SKCFLAGS : -fomit-frame-pointer -mfpmath=sse -msse3 -O2 -fno-schedule-insns2 -g -Wa,--noexecstack -fPIC -m64 -L/opt/lisa/os_v2/canopy/appdata/canopy-1.1.0.1371.rh5-x86_64/../../appdata/canopy-1.1.0.1371.rh5-x86_64/lib -lptf77blas -lptcblas -latlas 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
