Description

Description

Reference: https://github.com/conda-forge/mkl-service-feedstock/pull/38

Context: MKL dropped OSX support from the 2024.0 release. In the pytensor conda-forge package, we depend on the mkl-service package for BLAS with Windows and non-ARM Linux/OSX. Is there a better modern alternative these days for Intel OSX? Would it be feasible to switch to OpenBLAS?

Research direction

Start by reading the referenced mkl-service-feedstock pull request and inspecting the pytensor conda-forge package metadata for its current BLAS dependencies. Investigate modern BLAS options for Intel macOS, including whether OpenBLAS is feasible. Done means documenting a supported alternative and establishing whether the package dependency can be changed without losing required functionality.
