PyPi has open3d 0.12 only for Python 3.8 and earlier, not for 3.9

[jackjansen]

The entry for Open3D in pypi states it is compatible with Python 3.8 and earlier.

So if you use pip install open3d in Python 3.9 you get an error Could not find a version that satisfies the requirement open3d.

Is the current version of open3d really incompatible with Python 3.9? If so: any estimate when this could be fixed?

Or possibly this is just an oversight, and someone just forgot to update setup.py when Python 3.9 came out...

(Note that downgrading Python to 3.8 is less and less an option, now that Python 3.9 has been out for 4 months. For example, if you use brew on MacOS and you use other packages like libpcl then the brew formulas have already tied those packages to Python 3.9).

Python 3.9 support is planned soon. This is one blocker:
tensorflow/tensorflow#44485

Any updates on this yet?

[ssheorey]

Tensorflow is planning to support Python 3.9 by the end of April. Open3D should be able to support Python 3.9 after that (i.e. after release 0.13).
In the mean time, please use pyenv or conda with pip to install and run Python 3.8 and other Python packages with Open3D.

@ssheorey wonderful!

(note that for me at least the issue isn't with open3d per se, but with dependency on multiple packages. So now I have a dependency on open3d, which means I have to use Python <= 3.8 and a dependency on another package which requires python 3.9 (for the most recent version, of which I need a specific feature). I'm hoping the Python stable API efforts will come to fruition soon, that should fix most of this.)

So as of today, although their website doesn't officially say they support Python 3.9, I've just tried installing it on my Python 3.9.5 and it worked. (Windows.) Given this, is Open3D able to support Python 3.9 now?

[ssheorey]

We would prefer to wait for the official support, since this likely means they are ironing out the last few bugs. We would encourage you to try building Open3D + Tensorflow with Python 3.9 and let us know if there are any issues. Please use Python 3.9.1 or later due to this undefined behavior issue with Pybind11:
python/cpython#22670

It seems Python 3.9 is now officially supported for TensorFlow 2.5+.

Hi, I'm wondering what is the current status of open3d for Python 3.9.x?

Ubuntu is pushing the upgrade as of Aug 2021 to 21; this comes with Python 3.9. open3d still does not install with pip...
any plans to release it?
