When running XLA_PYTHON_CLIENT_MEM_FRACTION=0.3 ros2 launch car_ros2 car_sim.launch.py
I get this traceback. I have ensured both ROS is installed and sourced, as well as the colcon ws.

I am in the process of troubleshooting this, but it seems like the car_dynamics module has not been installed in my environment. I have followed the instructions in README.md

I have verified it shows up in pip list

➜  anycar git:(main) ✗ pip list | grep car_dynamics
car-dynamics                         0.0.0            /home/vinny/code/github.com/LeCAR-Lab/anycar/install/car_dynamics/lib/python3.10/site-packages

Hi,

It seems the issue arises because ROS2 is not recognizing the Python interpreter path, which prevents it from locating the necessary car_dynamics module. Here’s a solution to explicitly add the Python interpreter path for ROS2:

  1. Identify the Python executable path:

    which python

  2. Get the path to Python packages:

    python -c "import site; print(site.getsitepackages()[0])"

  3. Set the environment variables:

    Replace PATH-OF-PYTHON and PATH-OF-PYTHON-SITE-PACKAGES with the paths obtained in the steps above:

    export PYTHON_EXECUTABLE=PATH-OF-PYTHON
export PYTHONPATH=PATH-OF-PYTHON-SITE-PACKAGES:$PYTHONPATH

These steps will help ROS2 locate the necessary Python modules. We’ve also updated our README to reflect these setup instructions.

I tried the above, but it didn't help on my environment. It seems like colcon / ros / setup.py is not installing the car_dynamics library internally properly.

On my machine

Notice how site-packages is empty.

However, I was able to go past the error by doing this.

export PYTHONPATH=$PYTHONPATH:/home/vinny/code/github.com/LeCAR-Lab/anycar/car_dynamics

I encountered the same issue, and neither of the above methods could resolve it. My Install folder is also empty.

Could you try installing colcon in the anycar mamba environment

pip install -U colcon-common-extensions

I tried this command, but it seems it didn't solve the problem.

A solution please

@alexbuyval
Copy link

To solve this issue I have added in the car_dynamics/setup.py the following sub-directories in packages list:

    packages=['car_dynamics', 'car_dynamics/controllers_jax', 'car_dynamics/controllers_torch', 'car_dynamics/analysis', 
              'car_dynamics/envs', 'car_dynamics/models_jax', 'car_dynamics/models_torch', 'car_dynamics/modules'],

And then run colcon build again

However, I have another error now:

I have checked that nvidia-cudnn-cu12 is installed in anycar env.
Any ideas?

I tried to install all packages by conda, but I encontered with another error

AttributeError: module 'jax.interpreters.pxla' has no attribute 'ShardedDeviceArray'

Looks like ShardedDeviceArray attribute is deprecated and it is needed downgrade jax version.

@WENLIXIAO-CS could you, please, output the list of all python packages and its versions from your environment?
