Open3d availability in Python 3.9 pip

[jackjansen]

Now that #3611 has been merged I get the impression that open3d could finally be available for Python 3.9 installation through pip.

Is there an expected time for when this will be available?

Python 3.9 release wheels will be available on PyPI for the next release 0.14 onward. In the mean time, you can use the devel wheels:

Ok, I think I'll wait for 0.14, and hope it comes soon. I don't want to contemplate teaching my cicd jobs how to do this for all three of osx/win/linux:-(

For CI/CD, I would recommend downloading a fixed commit development wheel for each platform and using that for repeatability. We do something similar with many 3rd party packages (C++ source code) in Open3D. We store the 3rd party packages as a github release in the open3d_downloads repo. This has a fixed URL that can be used by tools such as CMake (C++) and pip install (Python).
