I don’t see mkl and mkl-service in 5.9.1. Those are relevant for high-performance linear algebra (assuming you’re on an intel processor).

Can you try running `conda install "libblas=*=*mkl"` in your 5.9.1 env? This helped another user [here](https://discourse.pymc.io/t/importing-pymc-and-sampling-are-slow-on-macbook-i-get-blas-warning/12648/7),
