numpy.disutils.system_info.NotFoundError: no lapack/blas resources found
Solution 1
It's possible that you have unmet dependencies. When I had this error, I was able to fix it by installing two packages:
sudo apt-get install libblas-dev liblapack-dev
Solution 2
Install following libraries (Ubuntu 20.04):
sudo apt-get install libatlas-base-dev libblas3 liblapack3 liblapack-dev libblas-dev gfortran
and then install python packages using pip.
Solution 3
If anyone has a similar issue with Scipy installation on FreeBSD - it can be fixed quite simply by installing necessary packages on the system itself using pkg
command:
pkg install blas
pkg install lapack

Problem: Linking numpy to correct Linear Algebra libraries. Process is so complicated that I might be looking for the solution 6th time and I have no idea whats going wrong. I am on Ubuntu 12.04.5. I reinstalled blas and lapack and then reinstalled numpy using pip. I did that in system environment and then also tried in virtualenv environment. None of the things seem to be working.
Here is my
numpy.__config__.show()
:lapack_info: NOT AVAILABLE lapack_opt_info: NOT AVAILABLE openblas_lapack_info: NOT AVAILABLE blas_info: NOT AVAILABLE atlas_3_10_blas_threads_info: NOT AVAILABLE atlas_threads_info: NOT AVAILABLE blas_src_info: NOT AVAILABLE atlas_3_10_threads_info: NOT AVAILABLE atlas_blas_info: NOT AVAILABLE atlas_3_10_blas_info: NOT AVAILABLE lapack_src_info: NOT AVAILABLE atlas_blas_threads_info: NOT AVAILABLE openblas_info: NOT AVAILABLE blas_mkl_info: NOT AVAILABLE blas_opt_info: NOT AVAILABLE atlas_info: NOT AVAILABLE atlas_3_10_info: NOT AVAILABLE lapack_mkl_info: NOT AVAILABLE mkl_info: NOT AVAILABLE
This is a very common error and has lots of solution depending on the user's environment and history. I recently went through the whole process of installing BLAS and LAPACK as instructed here: https://stackoverflow.com/a/9173550/3413239. I was able to successfully install both.
However, I initially had these libraries: (
ls /usr/lib | grep blas
)libopenblas.so.0 openblas-base/ libblas.so.3gf libblas.3
How should I link my numpy to linear algebra libraries. Is it mandatory to have all the linaear algebra libraries? i.e. lapack, blas, atlas?
I am assuming once the numpy is linked all other modules like scipy and Orange will work.
