Failed to instantiate plugin 'ProcessPlanningInputTaskFactory'

I've installed tesseract_python using the instructions in the readme. I am using Ubuntu 20.04 (via WSL2 on Windows 11).

Once I start the listed example tesseract_planning_example_composer I received the following error:

You can set logging level with TRAJOPT_LOG_THRESH. Valid values: FATAL ERROR WARN INFO DEBUG TRACE. Defaulting to ERROR

The other examples seem to run fine. Both tesseract_collision_example, and tesseract_kinematics_example run without errors and provide output to the terminal. tesseract_planning_example_no_composer also runs as expected and provides output to the terminal. Furthermore, on localhost:8000 this example also produces a visual of a robot moving along a trajectory.

Did I miss any installation instructions or am I doing something wrong?

The plugins should automatically configure when using the Python packages from pip. I have not tested on WSL so I do not know if there are some weird behaviors that differ from normal Linux environments.

I ran the example again with:

tesseract_common.setLogLevel(tesseract_common.CONSOLE_BRIDGE_LOG_DEBUG)

This did result in some more log messages regarding a Bad file descriptor:

Are there any checks I could do?

dave992 commented

I also tested it on Windows 11 directly (so not using WSL2) and I am getting the exact same error. The only difference is some of the paths.

It looks like there were changes to the newer version of tesseract_planning. The configuration files are for the newer plugin system that hasn't been updated in the Python wrappers yet.

In tesseract_planning, run:

git checkout 0.18.5

This will check out a version that is compatible.

dave992 commented

Thanks. it does not crash anymore after using the 0.18.5 version. I do not get the visual on http://localhost:8000 yet, but I first need to have a look at why that might be.
