Suppress spurious compiler warnings on first import of omas #289
Description
On first import of omas, the compilation of the cython extensions will dump a ton of warnings.
See e.g.:
And this continues for O(100) lines. IMHO this is quite confusing for new users.
It would be nice if there was a way to suppress these or even better build extensions as part of the packaging to in addition to avoiding these warnings, one also avoids the slowdown on the first import.
