Thanks! Interesting, I wonder if that is also what has caused tensorflow to not 
go up to 3.12 for now. From what I read somewhere (I think on an archived 
tensorflow mailing list or something) the linux builds are up, but not the 
MacO$ and Windoze builds. Both of which, if I had my way, should never have 
been allowed even indirectly into any professional environment.
