Hi @GSKun1,

Which ROS, Ubuntu, and Python version are you using? This error may happen because you are trying to use a version of Python that is not the same as the version that ROS uses (more info in the answers to this question. In some cases, running pip install rospkg may solve the issue.

ROS melodic,ubuntu 18.04,python 3.11.7

Hi,
Thank you for your answer.
After I run pip install rospkg, the error is reduced but still exists as shown below

Ok, we made some progress. The error from _tf2 import dynamic module does not define module export function now seems to happen because tf2 is compiled using Python 2.7, while you are using Python 3. Some options I'd try:

• Try creating a Python 2.7 virtual environment and run MADER from it (see the answer to this question)

• Try compiling tf2 for Python 3 (see the answer to this question)

• Try changing these shebang lines to #!/usr/bin/env python2.7

Thank you.
I'll try again.

I successfully solved the problem when I tried the third solution, thanks!
