Yeah, sorry … something changed on my end. I have tested this and forgot:

It _seems_ that scipy doesn't actually call CBLAS API, as opposed to
numpy. Observe:

$ find /data/pkg/lib/python3.11/site-packages/scipy/ -name '*.so' | xargs -L 1 nm -g |grep cblas_
$ find /data/pkg/lib/python3.11/site-packages/numpy/ -name '*.so' | xargs -L 1 nm -g |grep cblas_
                 U cblas_caxpy
                 U cblas_cdotc_sub
                 U cblas_cdotu_sub
                 U cblas_cgemm
                 U cblas_cgemv
                 U cblas_csyrk
                 U cblas_daxpy
                 U cblas_ddot
                 U cblas_dgemm
                 U cblas_dgemv
                 U cblas_dsyrk
                 U cblas_saxpy
                 U cblas_sdot
                 U cblas_sgemm
                 U cblas_sgemv
                 U cblas_ssyrk
                 U cblas_zaxpy
                 U cblas_zdotc_sub
                 U cblas_zdotu_sub
                 U cblas_zgemm
                 U cblas_zgemv
                 U cblas_zsyrk

So the above could be a hotfix for the current version of scipy.

The wip/hmmlearn package will have to be fixed then, but has time for
after the branching.


Alrighty then,

Thomas
