In contrast to a comment in one of the older versions of meta.yaml that suggested that "Numpy version is not constrained, thanks to pybind11 magic", I found that you
need numpy at build time, and
it only works at the moment as one of the dependent packages has numpy as a dependency.
The build will then be numpy API specific.
with this fix, you'll need to specify the numpy version with --numpy=1.xx in conda build.
