Object Detector App not loading (libhdfs.so error)

Greetings. I’ve been using the Object Detector app without issues until now. When I go to load the app it shows below error message and then defaults to the Birdfeeder app. Not sure what I did to the camera to get to this point other than I was following the ‘train your own images tutorial’ when the system started to malfunction. I’m currently running Vizy version 0.2.131. Any insight or solutions to this issue is most appreciated. Other than this issue the camera is fantastic. Rex H.

Sorry for the problems, but many thanks for the console excerpt! It looks like the most recent project is in a weird state. Try going into the console and running these commands:

cd ~/vizy/etc
mv object_detector.json object_detector.json.bak

then restart Object Detector. This will force Object Detector to load the default project instead of the (possibly) defunct project. Let me know what you find.


Worked like a charm. Thanks for your quick response and solution. Rex

Thanks! We’ll have someone contact you by email to see if we can identify what went wrong.
