Dear community,

I want to find the location of the openblas library that Numpy calls.

Hi, I suspect you're tied to Python 3.6 due to some HPC cluster or similar, but in case you can upgrade to Python 3.8 or newer, NumPy 1.24 introduced show_runtime() that contains this information: https://numpy.org/doc/stable//reference/generated/numpy.show_runtime.html . It's possible that installing `threadpoolctl` and running `python -m threadpoolctl -i numpy` works on older Python/NumPy as well to tell you the same information, I don't know. András

Then I did the following:

[root@computer02 ~]# python3 Python 3.6.8 (default, Nov 16 2020, 16:55:22) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux Type "help", "copyright", "credits" or "license" for more information.

import numpy numpy.show_config() blas_mkl_info: NOT AVAILABLE blis_info: NOT AVAILABLE openblas_info: libraries = ['openblas', 'openblas'] library_dirs = ['/usr/local/lib'] language = c define_macros = [('HAVE_CBLAS', None)] blas_opt_info: libraries = ['openblas', 'openblas'] library_dirs = ['/usr/local/lib'] language = c define_macros = [('HAVE_CBLAS', None)] lapack_mkl_info: NOT AVAILABLE openblas_lapack_info: libraries = ['openblas', 'openblas'] library_dirs = ['/usr/local/lib'] language = c define_macros = [('HAVE_CBLAS', None)] lapack_opt_info: libraries = ['openblas', 'openblas'] library_dirs = ['/usr/local/lib'] language = c define_macros = [('HAVE_CBLAS', None)]

However, the ls /usr/local/lib folder is empty and I would like to know how to see where openblas used by numpy is?
