  • NOTE: the platform (based on buildroot) is now a bit ahead of the host (assuming Ubuntu 17.04). Some of the differences will likely disappear with future Ubuntu releases, but in the meantime be aware that:
Software Platform Ubuntu 17.04
gcc / g++ 7.2 6.3
python 3.6 3.5
boost 1.64 1.62

For most, this should make no difference. Because g++ 7.2 is a bit more strict than 6.3, you may get a few additional warnings when compiling your code for platform compared to host. You should fix them anyway as the host setup will move to g++7 soon.

  • Updated tiny-dnn to latest version from GitHub (there has not been any release lately). This changes the API a bit, see updated ObjectRecognition components in jevoisbase.
  • Small improvements on jevois-flash-card to avoid mistakenly erasing large hard disks.
  • This releases changes the platform operating system (buildroot). You need to get the new JeVois Debian packages from https://jevois.usc.edu
  • Recommended upgrade workflow: see http://jevois.org/tutorials/ProgrammerSetup.html under Upgrading.
  • Added new help2 command-line interface command to show a more compact help message about the current vision module only.
  • Added profiling to darknet, which will allow one to easily find out which deep neural network layers take a lot of time to compute.
