I got an error when connecting to Ubuntu training using FinalShell on my MAC

Can you tell me how to solve the problem, I reproduce the P2B code is successful

Sorry I haven't tested our code on the Mac. Regarding the qt-related errors you mentioned, I can only guess that it is probably related to the visual code.

Please check the installation of pyqt, mayavi, vtk and if there are calls like import mayavi and mayavi_show in the code you are running?

Thanks, I have replicated successfully, I now use the window system, demo_tracking.py run failed, can you take an example, the parameters are not clear what it means

Please give the specific error message so that I can check the code error.

PS： In fact, demo_tracking.py is used to debug when you change the network architecture. Hence, you don't need to run demo_tracking.py, just follow the README to train and test.
