@ideafold We no longer maintain the Amlogic nn api repository, please use other APIs

I just use image_classify_224x224 to test whether NPU works.
Actually in my app it just only use Tengine lite.

#5

I have told you many times that this api is no longer maintained, and you can’t use it on the latest NPU, so you can’t use it to test whether the NPU works

#6

In last post, I just want to highlight that “in my app it just only use Tengine lite”.

ok.
I wil switch to use aml_npu_demo_binaries.
Thanks.
