@Stefan Br���ns: I've got an update ready for OpenBLAS to 3.20 with a number of fixes on top to hopefully address the conflicts between it and netlib lapack. It's been a tedious task as there were two issues in OpenBLAS upstream that required addressing. I'm still in conversations with the OpenBLAS project. I'll submit it these days. This will hopefully make switching between OpenBLAS's implementation and netlib more easy. The issue that led to the rejection of Numpy is home-made. For my HPC packages I try everything to avoid this.
