Neural Network changes in V9

jimmy_d shared another spectacular analysis of the NN on v9. His first post analyses the NN called AKNET_V9. Here are some details but you should go and read the original post on TMC:

  • One unified camera network handles all 8 cameras vs. a sepate network per camera on previous versions
  • Same weight file being used for all cameras (this has pretty interesting implications and previously v8 main / narrow seems to have had separate weights for each camera)
  • Full resolution for the 3 front cameras and back camera (1280x960) and 12 the resolution for pillar and repeater cameras (640x480)
  • All cameras analyze 2 frames at the same time (most likely so each camera can see motion)
  • The size of the network makes jimmy_d wonder the amount of training data that Tesla is using in their backend and if they are manually tagging all the images since it seems a ton of manual labor, on his own words «there aren’t enough humans to label this much data»
  • I really like his closing statement As a neural network dork I couldn’t be more pleased.»

In a later post jimmy_d mentions that AKNET_V9 might not be the network that’s currently driving the car since he thinks it’s too big to run on HW2 or HW2.5. His best guess is that it can only run at 3 fps and that doesn’t seem fast enough to be usable. However, it seems posible that this is the network that FSD is using since in HW3 it could run at 30 fps. The current firmware includes a number of different NN and it doesn’t seem easy to understand what is use and what is not, a bunch of the NN that are there are at evolution of what we got in 8.1 but AKNET_V9 seems a completely different beast.

As always, it is delightful to read you jimmy_d, keep up the good work!

Free Android app that lets you share navigation from your phone to your car from multiple sites. Didn’t V9 include this feature? Yes. Did this feature work on most apps other than Google Maps? Unfortunately not, so this is a great alternative!

See app in Google Play


Software update process from the app in V9

Explained by beastpilot: «You get a normal notification, then in the app you can trigger it. Once you trigger it, you get ‘cancel update’ for 2 minutes, as well as a notification that a SW update is about to start. Once it starts the ‘cancel update’ goes away, and then you get a notification it finished once done.»

3 simultaneous apps on V9, woot?!

It clearly seems like an unintended feature (A.K.A. bug) because it goes away if you then start the navigation, of if you don’t have the camera up and start backing up. But one can only dream that Tesla would bring something like that to the Model S and Model X, this would be superior to the previous «split screen» if they let people re-arrange them.


What the acronym?

As Tesla fan, I find myself sometimes having to remember what are all those acronyms, here is a list of the ones you can find in this issue.

  • FSD - Full Self-Driving
  • HW3 - Hardware 3
  • NN - Neural Network
  • V9 - Version 9
  • M3 - Model 3
  • SW - Software
  • TPMS - Tire Pressure Monitoring System
