3 weeks ago With @hhslepicka we released a new lapack95 that specifies openblas as the variant for MacOS (PR link).
No luck still:
$ conda create -n bmad-test bmad=20240922 libblas=*=*openblas

Is it worth having multiple bmad builds with libopenblas versions?
Should we run_constrain libopenblas to <=0.3.27?
Or even... is this something that should be reported to libblas/libopenblas?
Edit: OK, this is pending upstream in blas-feedstock (https://github.com/conda-forge/blas-feedstock/pull/121)
I'm not sure what the right approach here is.
Solution to issue cannot be found in the documentation.
Issue
The symbol in question comes from lapack95: https://github.com/conda-forge/lapack95-feedstock/issues/7
pytao and any other libraries which use
libtao.dylibwill fail with the following message whenlibblas=*=accelerateis installed:Our previous workaround was to use libblas instead (
conda install "libblas=*=*_openblas"), however it appears that this downgrades bmad. It's no longer installable with openblas:Installed packages
