Different inference performance on Mac and Windows #101

Closed lukashubl closed 5 years ago

lukashubl commented 5 years ago

I am trying to test my model on the simulator for mac. I use the first track and the car always crashes in the first corner in front of the bridge. The strange thing is that the same model drives perfectly on the windows simulator. Any suggestions?

Do you have a GPU on your Windows computer? That would be the most likely cause of the difference, otherwise it could just be general CPU performance differences between the two (for instance, the Mac may not be performing inference fast enough to keep up with the images coming in).
