Hi all, We have never had a working Windows build on conda-forge for SciPy. This is a bit painful, since it means that pretty much all SciPy/PyData users on Windows can't go "all conda-forge", and mixing the defaults and conda-forge channels is fairly fragile. The solution is now a lot closer, since rather than a Fortran compiler project it's now a devops project: Intel provided permission and a license to use the Intel Fortran compiler, which is the best way to build SciPy on Windows. So "all" that's needed is set that up on a VM somewhere and connect it to conda-forge. This is still nontrivial, it requires some good devops skills. Marius van Niekerk, one of the conda-forge core team members, provided details on status and next steps at https://github.com/conda-forge/scipy-feedstock/issues/80. He could really use a hand. If there's anyone here with the interest and skills to help out here, this would be a really high-impact contribution! Cheers, Ralf
