undefined symbol: sgemv_thread_n (solved (?))
Hi, I removed openblas: goran at M6800:~$ sudo dpkg --purge libopenblas-dev and goran at M6800:~$ sudo dpkg --purge libopenblas-base which left me with goran at M6800:~$ dpkg -l | grep blas pi libblas-dev:amd64 3.7.1-3ubuntu2 amd64 Basic Linear Algebra Subroutines 3, static library ii libblas3:amd64 3.7.1-3ubuntu2 amd64 Basic Linear Algebra Reference implementations, shared library And now everything just works.
