Pydrake has issue with python 3 point 9

Is Python3.9 supported?

I got this error with Python3.9:

  File "/home/drake/drake/drake-build/install/lib/python3.6/site-packages/pydrake/common/__init__.py", line 8, in <module>     from ._module_py import * ModuleNotFoundError: No module named 'pydrake.common._module_py'

There is no "python3.9" folder in .../install/lib.

I am running Ubuntu 18, and I am building Drake from source with latest github commit in master.

EDIT: Can someone explain how exactly Drake sets up pydrake?

It seems it detects the default Python installation somewhere automatically. I tried with a new installation, the default python was 3.8, and I also install:

apt install -y python3.10

Then I followed Drake python setup instructions.

git clone https://github.com/RobotLocomotion/drake.git
mkdir drake-build
cd drake-build
cmake ../drake
make -j

Pydrake only became available in 3.8. How to make it available for 3.10?

The current version of Pydrake (1.11.0) is officially supported on Ubuntu 20.04 with Python 3.8 and Ubuntu 22.04 with Python 3.10 when building from source. However, we recommend that most users use a binary release, and don't try to rebuild Drake from scratch themselves.

There are precompiled wheels at https://pypi.org/project/drake/ aka pip install drake; helpful installation details are at https://drake.mit.edu/pip.html. The wheels when run on Ubuntu support Python versions 3.8, 3.9, 3.10, or 3.11.

For example:

python3 -m venv env
env/bin/pip install --upgrade pip
env/bin/pip install drake
source env/bin/activate

For additional details, see https://drake.mit.edu/installation.html for full instructions and supported versions.

The last version of Pydrake to support Ubuntu 18.04 was v1.1.0 (released in March of 2022). If you need a newer version of Pydrake, you'll need to use a newer version of Ubuntu.
