Hello DeepVariant team, thanks for great tool.

After we tried to upgrade our deepvariant installation to the latest release we encountered a problem with numpy installation, which I described here. The problem is caused by wheel - not by numpy itself, but this error raised several questions for me:

• For now looks like installing deepvariant with https://github.com/google/deepvariant/blob/r1.1/build-prereq.sh will fail on non Ubuntu 16.04 due to numpy problem. This problem won't be fixed in older versions of numpy I think - only wheel can fix it now. Or you can switch numpy 1.18.5 for 1.19.3+?

• Part of this problem origins from using Python 3.6 if I understand correctly this, maybe you should update version of Python installing by script?

• I've just tested your installation script with one change: I added Ubuntu 18.04 to this check - looks like all good. If a problem was in Ubuntu 14.04 - maybe wide this check a bit? Even Ubuntu 20.04 is released half a year ago.
