I just attempted this and it works properly. Can you confirm that you followed all the previous steps without skipping any?

If so, I would recommend removing the repository and starting from the beginning again.

Hi,

thanks for your answer, but I solved it. In the guide document, after running the simulation, it is necessary to source the instal/setup.py again.

my best,
