QuickVision example fails with SIGABRT

It's hard to duplicate this, but...

I killed the webserver process and it seems to work, so it might be that it's running out of memory.

FWIW memory:

The quickvision robot program is 109m. If I import numpy then vsz goes from 13M to 50M. Importing cscore goes from 50M to 75M. Not 100% sure how that affects actual memory pressure.

Anyone running into this should try to disable the NI webserver:

python -m robotpy installer niweb disable

You mostly only need it to set the IP address of your robot. If there is ever a time you need to enable it again:

python -m robotpy installer niweb enable
