tensorflow didn't work on 3.7 for a solid 8 months because some people at google very unwisely decided that `async` and `await` were great choices for variable names, despite PEP492 landing in 2015.
that's because tensorflow is advertisement for Google and while it's technically open-source, it doesn't stand for any kind of community-project, it's all there to show off (and ingrain in its users) the way Google wants things to Go (just look at the byzantine Bazel-build-processes - tensorflow taking hours to build and pytorch about 10minutes...).
