When I use python main.py in terminal, the above is unfolded there. I think there is an mismatch for PySide2 library maybe. The following is shown in my terminal.

>>> import PySide2
>>> print(PySide2.__version__)
2.0.0~alpha0

Hi @bryanibit thank you for reporting the issue. I haven't used the GUI in a while but I'll check if I get the same error.

Please note that the GUI is not really functional yet unfortunately. At the moment, you are better off using the frenet.ipynb notebook, where the transformation is used too.

However, I am planning to re-implement the GUI allowing one to create trajectories from frenet polynomials.

@bryanibit I used a conda environment with python3. I'll add the environment.yml file. After you've activated the environment which should install the required dependencies you can execute frenet.sh which will compile the ui design file with uic and run main.py for you.

These are the dependencies that are needed to run the GUI.

But as I mentioned, it is not functional yet. Only pressing the Set lateral button will draw a line, nothing more.
