IMX8MP error running TensorFlow Lite case

[ace12]

When you run the IMX8MP TensorFlow Lite example, adding the argument -a 1 will print the warning message WARN: NNAPI delegate execution provider isn't linked or NNAPI delegate isn't supported on the platform!
Currently it can only run on cpus, not Npus

Could you tell me how to solve this

Refer this guide:https://www.nxp.com/docs/en/user-guide/IMX-MACHINE-LEARNING-UG.pdf

Ok, thanks. I just saw in the bb file that NNAPI is not open

[Zhiming_Liu]

NNAPI is not recommended.

[ace12]

So which one is recommended to open

[Zhiming_Liu]

You don't need modify bb file.

But I don't have a libvx_delegate.so file
