Autonomous Vehicles DRIVE AGX Orin DRIVE AGX Orin General
1

Software Version
DRIVE OS 6.0.6

Target Operating System
Linux

Hardware Platform
DRIVE AGX Orin Developer Kit (not sure its number)

I try to run the HelloWorldNode sample of CGF base on the cgf_demo_sample(Compute Graph Framework SDK Reference: Demo Pipeline Introduction)

it shows the error message bellow:

the key error is here:


terminate called after throwing an instance of 'std::runtime_error'

what(): Clone Manager: Unable to instantiate state machine: helloworld_process0

the “helloworld_process0” is the name of HelloWorldNode I use in the app.json, and now I don’t where can I find the state machine of this porcess

Dear @TomFord,
Could you share the followed steps to run hello world node?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Is this still an issue to support? Any result can be shared? Thanks
