iMX8M Plus: TensorFlow Lite Video classification example is aborted on NPU.

Hi all,

I have the 8MPLUSLPD4-EVK Evaluation Kit and I am trying TensorFlow Lite Video classification example according to following URL.

https://tfhub.dev/tensorflow/lite-model/movinet/a0/stream/kinetics-600/classification/tflite/int8/1

Running the attached python program will cause an abort.

1. Download .tflite file and rename.

root@imx8mp-lpddr4-evk:~# wget https://tfhub.dev/tensorflow/lite-model/movinet/a0/stream/kinetics-600/classification/tflite/int8/1?lite-format=tflite
root@imx8mp-lpddr4-evk:~# mv 1\?lite-format\=tflite movinet_a0_stream_k600_int8.tflite

2. Run the attached program.

root@imx8mp-lpddr4-evk:~# python3 classifier.py

 Result:

Vx delegate: allowed_cache_mode set to 0.
Vx delegate: allowed_builtin_code set to 0.
Vx delegate: error_during_init set to 0.
Vx delegate: error_during_prepare set to 0.
Vx delegate: error_during_invoke set to 0.

i.MX Yocto Project(kirkstone-5.15.32-2.0.0) is running on EVK.

How can I solve this problem?
